Adult Indications and Dosage

FDA-Labeled Indications and Dosage (Adult)

How to Use Etonogestrel and Ethinyl Estradiol Vaginal Ring
  • To achieve maximum contraceptive effectiveness, etonogestrel and ethinyl estradiol vaginal ring must be used as directed . One etonogestrel and ethinyl estradiol vaginal ring is inserted in the vagina. The ring is to remain in place continuously for three weeks. It is removed for a one-week break, during which a withdrawal bleed usually occurs. A new ring is inserted one week after the last ring was removed.
  • The user can choose the insertion position that is most comfortable to her, for example, standing with one leg up, squatting, or lying down. The ring is to be compressed and inserted into the vagina. The exact position of etonogestrel and ethinyl estradiol vaginal ring inside the vagina is not critical for its function. The vaginal ring must be inserted on the appropriate day and left in place for three consecutive weeks. This means that the ring should be removed three weeks later on the same day of the week as it was inserted and at about the same time.
  • Etonogestrel and ethinyl estradiol vaginal ring can be removed by hooking the index finger under the forward rim or by grasping the rim between the index and middle finger and pulling it out. The used ring should be placed in the sachet (foil pouch) and discarded in a waste receptacle out of the reach of children and pets (do not flush in toilet).
  • After a one-week break, during which a withdrawal bleed usually occurs, a new ring is inserted on the same day of the week as it was inserted in the previous cycle. The withdrawal bleed usually starts on Day 2-3 after removal of the ring and may not have finished before the next ring is inserted. In order to maintain contraceptive effectiveness, the new ring must be inserted exactly one week after the previous one was removed even if menstrual bleeding has not finished.
How to Start Using Etonogestrel and Ethinyl Estradiol vaginal ring

Consider the possibility of ovulation and conception prior to the first use of etonogestrel and ethinyl estradiol vaginal ring.

  • No Hormonal Contraceptive Use in the Preceding Cycle: The woman should insert etonogestrel and ethinyl estradiol vaginal ring on the first day of her menstrual bleeding. etonogestrel and ethinyl estradiol vaginal ring may also be started on Days 2-5 of the woman's cycle, but in this case a barrier method, such as male condoms with spermicide, should be used for the first seven days of etonogestrel and ethinyl estradiol vaginal ring use in the first cycle.
  • Changing From a Combined Hormonal Contraception (CHC): The woman may switch from her previous CHC on any day, but at the latest on the day following the usual hormone-free interval, if she has been using her hormonal method consistently and correctly, or if it is reasonably certain that she is not pregnant.
  • Changing From a Progestin-Only Method (progestin-only pill [POP], Implant, or Injection or a Progestin-Releasing Intrauterine System [IUS]): The woman may switch from the POP on any day; instruct her to start using etonogestrel and ethinyl estradiol vaginal ring on the day after she took her last POP. She should switch from an implant or the IUS on the day of its removal, and from an injectable on the day when the next injection would be due. In all of these cases, the woman should use an additional barrier method such as a male condom with spermicide, for the first seven days.
  • Use after Abortion or Miscarriage: The woman may start using etonogestrel and ethinyl estradiol vaginal ring within the first five days following a complete first trimester abortion or miscarriage, and she does not need to use an additional method of contraception. If use of etonogestrel and ethinyl estradiol vaginal ring is not started within five days following a first trimester abortion or miscarriage, the woman should follow the instructions for "No Hormonal Contraceptive Use in the Preceding Cycle". In the meantime, she should be advised to use a non-hormonal contraceptive method.
  • Following Childbirth: The use of etonogestrel and ethinyl estradiol vaginal ring may be initiated no sooner than four weeks postpartum in women who elect not to breastfeed, due to the increased risk of thromboembolism in the postpartum period.
Deviations from the Recommended Regimen
  • To prevent loss of contraceptive efficacy, advise women not to deviate from the recommended regimen. Etonogestrel and ethinyl estradiol vaginal ring should be left in the vagina for a continuous period of three weeks.
  • Inadvertent Removal or Expulsion: Etonogestrel and ethinyl estradiol vaginal ring can be accidentally expelled, for example, while removing a tampon, during intercourse, or with straining during a bowel movement. Etonogestrel and ethinyl estradiol vaginal ring should be left in the vagina for a continuous period of three weeks. If the ring is accidentally expelled and is left outside of the vagina for less than three hours, contraceptive efficacy is not reduced. Etonogestrel and ethinyl estradiol vaginal ring can be rinsed with cool to lukewarm (not hot) water and reinserted as soon as possible, but at the latest within three hours. If etonogestrel and ethinyl estradiol vaginal ring is lost, a new vaginal ring should be inserted and the regimen should be continued without alteration.
  • If etonogestrel and ethinyl estradiol vaginal ring is out of the vagina for more than three continuous hours:
  • During Weeks 1 and 2: Contraceptive efficacy may be reduced. The woman should reinsert the ring as soon as she remembers. A barrier method such as condoms with spermicides must be used until the ring has been used continuously for seven days.
  • During Week 3: The woman should discard that ring. One of the following two options should be chosen:
  1. Insert a new ring immediately. Inserting a new ring will start the next three-week use period. The woman may not experience a withdrawal bleed from her previous cycle. However, breakthrough spotting or bleeding may occur.
  2. Insert a new ring no later than seven days from the time the previous ring was removed or expelled, during which time she may have a withdrawal bleed. This option should only be chosen if the ring was used continuously for at least seven days prior to inadvertent removal/expulsion.
  • In either case, a barrier method such as condoms with spermicides must be used until the new ring has been used continuously for seven days.
  • Prolonged Ring-Free Interval: If the ring-free interval has been extended beyond one week, consider the possibility of pregnancy, and an additional method of contraception, such as male condoms with spermicide, MUST be used until etonogestrel and ethinyl estradiol vaginal ring has been used continuously for seven days.
  • Prolonged Use of Etonogestrel and Ethinyl Estradiol Vaginal Ring : If etonogestrel and ethinyl estradiol vaginal ring has been left in place for up to one extra week (i.e., up to four weeks total), the woman will remain protected. Etonogestrel and ethinyl estradiol vaginal ring should be removed and the woman should insert a new ring after a one-week ring-free interval.
  • If etonogestrel and ethinyl estradiol vaginal ring has been left in place for longer than four weeks, instruct the woman to remove the ring, and rule out pregnancy. If pregnancy is ruled out, etonogestrel and ethinyl estradiol vaginal ring may be restarted, and an additional method of contraception, such as male condoms with spermicide, must be used until a new etonogestrel and ethinyl estradiol vaginal ring has been used continuously for seven days.
  • Ring Breakage: There have been reported cases of etonogestrel and ethinyl estradiol vaginal ring disconnecting at the weld joint. This is not expected to affect the contraceptive effectiveness of etonogestrel and ethinyl estradiol vaginal ring. In the event of a disconnected ring, vaginal discomfort or expulsion (slipping out) is more likely to occur. If a woman discovers that her etonogestrel and ethinyl estradiol vaginal ring has disconnected, she should discard the ring and replace it with a new ring.
In the Event of a Missed Menstrual Period
  1. If the woman has not adhered to the prescribed regimen (etonogestrel and ethinyl estradiol vaginal ring has been out of the vagina for more than three hours or the preceding ring-free interval was extended beyond one week), consider the possibility of pregnancy at the time of the first missed period and discontinue etonogestrel and ethinyl estradiol vaginal ring use if pregnancy is confirmed.
  2. If the woman has adhered to the prescribed regimen and misses two consecutive periods, rule out pregnancy.
  3. If the woman has retained one etonogestrel and ethinyl estradiol vaginal ring for longer than four weeks, rule out pregnancy.

Warnings

WARNING: CIGARETTE SMOKING AND SERIOUS CARDIOVASCULAR EVENTS
See full prescribing information for complete Boxed Warning.
CIGARETTE SMOKING AND SERIOUS CARDIOVASCULAR EVENTS: Cigarette smoking increases the risk of serious cardiovascular events from combination hormonal contraceptive (CHC) use. This risk increases with age, particularly in women over 35 years of age, and with the number of cigarettes smoked. For this reason, CHCs, including NuvaRing, should not be used by women who are over 35 years of age and smoke.
Thromboembolic Disorders and Other Vascular Problems
  • Stop etonogestrel and ethinyl estradiol vaginal ring use if an arterial thrombotic or venous thromboembolic event (VTE) occurs. Stop etonogestrel and ethinyl estradiol vaginal ring use if there is unexplained loss of vision, proptosis, diplopia, papilledema, or retinal vascular lesions. Evaluate for retinal vein thrombosis immediately.
  • If feasible, stop etonogestrel and ethinyl estradiol vaginal ring at least four weeks before and through two weeks after major surgery or other surgeries known to have an elevated risk of thromboembolism, and during and following prolonged immobilization.
  • Start etonogestrel and ethinyl estradiol vaginal ring no earlier than 4 weeks after delivery, in women who are not breastfeeding. The risk of postpartum thromboembolism decreases after the third postpartum week, whereas the risk of ovulation increases after the third postpartum week.
  • The use of CHCs increases the risk of VTE. Known risk factors for VTE include smoking, obesity, and family history of VTE, in addition to other factors that contraindicate use of CHCs.
  • Two epidemiologic studies1, 2, 3 that assessed the risk of VTE associated with the use of etonogestrel and ethinyl estradiol vaginal ring are described below.
  • In these studies, which were required or sponsored by regulatory agencies, etonogestrel and ethinyl estradiol vaginal ring users had a risk of VTE similar to COC users (see table below for adjusted hazard ratios). A large prospective, observational study, the Transatlantic Active Surveillance on Cardiovascular Safety of etonogestrel and ethinyl estradiol vaginal ring (TASC), investigated the risk of VTE for new users, and women who were switching to or restarting etonogestrel and ethinyl estradiol vaginal ring or COCs in a population that is representative of routine clinical users. The women were followed for 24 to 48 months. The results showed a similar risk of VTE among etonogestrel and ethinyl estradiol vaginal ring users (VTE incidence 8.3 per 10,000 WY) and women using COCs (VTE incidence 9.2 per 10,000 WY). For women using COCs that did not contain the progestins desogestrel (DSG) or gestodene (GSD), VTE incidence was 8.9 per 10,000 WY.
  • A retrospective cohort study using data from 4 health plans in the US (FDA-funded Study in Kaiser Permanente and Medicaid databases) showed the VTE incidence for new users of etonogestrel and ethinyl estradiol vaginal ring to be 11.4 events per 10,000 WY, for new users of a levonorgestrel (LNG)-containing COC 9.2 events per 10,000 WY, and for users of other COCs available during the course of the study1 8.2 events per 10,000 WY.

  • An increased risk of thromboembolic and thrombotic disease associated with the use of CHCs is well-established. Although the absolute VTE rates are increased for users of CHCs compared to non-users, the rates associated with pregnancy are even greater, especially during the post-partum period (see figure below).
  • The frequency of VTE in women using CHCs has been estimated to be 3 to 12 cases per 10,000 women-years.
  • The risk of VTE is highest during the first year of CHC use and after restarting a CHC following a break of at least four weeks. The risk of VTE due to CHCs gradually disappears after use is discontinued.
  • Figure 1 shows the risk of developing a VTE for women who are not pregnant and do not use CHCs, for women who use CHCs, for pregnant women, and for women in the postpartum period. To put the risk of developing a VTE into perspective: If 10,000 women who are not pregnant and do not use CHCs are followed for one year, between 1 and 5 of these women will develop a VTE.

1Includes low-dose COCs containing the following progestins: norgestimate, norethindrone, or levonorgestrel.

Toxic Shock Syndrome (TSS)
Liver Disease
Impaired Liver Function
Liver Tumors
High Blood Pressure
Vaginal Use
  • Etonogestrel and ethinyl estradiol vaginal ring may not be suitable for women with conditions that make the vagina more susceptible to vaginal irritation or ulceration. Vaginal/cervical erosion or ulceration in women using etonogestrel and ethinyl estradiol vaginal ring has been reported. In some cases, the ring adhered to vaginal tissue, necessitating removal by a healthcare provider.
  • Some women are aware of the ring on occasion during the 21 days of use or during intercourse, and sexual partners may feel etonogestrel and ethinyl estradiol vaginal ring in the vagina.
Gallbladder Disease
  • Studies suggest a small increased relative risk of developing gallbladder disease among CHC users. Use of CHCs may also worsen existing gallbladder disease.
  • A past history of CHC-related cholestasis predicts an increased risk with subsequent CHC use. Women with a history of pregnancy-related cholestasis may be at an increased risk for CHC-related cholestasis.
Carbohydrate and Lipid Metabolic Effects
  • Carefully monitor prediabetic and diabetic women who are using etonogestrel and ethinyl estradiol vaginal ring. CHCs may decrease glucose tolerance.
  • Consider alternative contraception for women with uncontrolled dyslipidemia. Some women will have adverse lipid changes while on CHCs.
  • Women with hypertriglyceridemia, or a family history thereof, may be at an increased risk of pancreatitis when using CHCs.
Headache
Bleeding Irregularities and Amenorrhea
Unscheduled Bleeding and Spotting
  • Unscheduled bleeding (breakthrough or intracyclic) bleeding and spotting sometimes occur in women using CHCs, especially during the first three months of use. If bleeding persists or occurs after previously regular cycles, check for causes such as pregnancy or malignancy. If pathology and pregnancy are excluded, bleeding irregularities may resolve over time or with a change to a different CHC.
  • Bleeding patterns were evaluated in three large clinical studies. In the North American study (US and Canada, N=1,177), the percentages of subjects with breakthrough bleeding/spotting ranged from 7.2% to 11.7% during cycles 1-13. In the two non-US studies, the percentages of subjects with breakthrough bleeding/spotting ranged from 2.6% to 6.4% (Europe, N=1,145) and from 2.0% to 8.7% (Europe, Brazil, Chile, N=512).
Amenorrhea and Oligomenorrhea
  • If scheduled (withdrawal) bleeding does not occur, consider the possibility of pregnancy. If the patient has not adhered to the prescribed dosing schedule, consider the possibility of pregnancy at the time of the first missed period and take appropriate diagnostic measures.
  • Occasional missed periods may occur with the appropriate use of etonogestrel and ethinyl estradiol vaginal ring. In the clinical studies, the percent of women who did not have withdrawal bleeding in a given cycle ranged from 0.3% to 3.8%.
  • If the patient has adhered to the prescribed regimen and misses two consecutive periods, rule out pregnancy.
  • Some women may experience amenorrhea or oligomenorrhea after discontinuing CHC use, especially when such a condition was pre-existent.
Inadvertent Urinary Bladder Insertion

There have been reports of inadvertent insertions of etonogestrel and ethinyl estradiol vaginal ring into the urinary bladder, which required cystoscopic removal. Assess for ring insertion into the urinary bladder in etonogestrel and ethinyl estradiol vaginal ring users who present with persistent urinary symptoms and are unable to locate the ring.

CHC Use Before or During Early Pregnancy
  • Extensive epidemiological studies have revealed no increased risk of birth defects in women who have used oral contraceptives prior to pregnancy. Studies also do not suggest a teratogenic effect, particularly in so far as cardiac anomalies and limb reduction defects are concerned, when taken inadvertently during early pregnancy. Discontinue etonogestrel and ethinyl estradiol vaginal ring if pregnancy is confirmed.
Depression
  • Carefully observe women with a history of depression and discontinue etonogestrel and ethinyl estradiol vaginal ring use if depression recurs to a serious degree.
Carcinoma of the Breasts and Cervix
  • Etonogestrel and ethinyl estradiol vaginal ring is contraindicated in women who currently have or have had breast cancer because breast cancer is a hormonally-sensitive tumor.
  • There is substantial evidence that CHCs do not increase the incidence of breast cancer. Although some past studies have suggested that CHCs might increase the incidence of breast cancer, more recent studies have not confirmed such findings.
  • Some studies suggest that CHCs are associated with an increase in the risk of cervical cancer or intraepithelial neoplasia. However, there is controversy about the extent to which these findings may be due to differences in sexual behavior and other factors.
Effect on Binding Globulins
  • The estrogen component of CHCs may raise the serum concentrations of thyroxine-binding globulin, sex hormone-binding globulin, and cortisol-binding globulin. The dose of replacement thyroid hormones or cortisol therapy may need to be increased.
Monitoring
  • A woman who is using etonogestrel and ethinyl estradiol vaginal ring should have a yearly visit with her healthcare provider for a blood pressure check and for other indicated healthcare.
Hereditary Angioedema
Chloasma

Adverse Reactions

Clinical Trials Experience

The following serious adverse reactions with the use of CHCs are discussed elsewhere.

  • Serious cardiovascular events and stroke.

Postmarketing Experience

The following adverse reactions have been identified during post-approval use of etonogestrel and ethinyl estradiol vaginal ring. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Drug Interactions

Consult the labeling of all concurrently-used drugs to obtain further information about interactions with hormonal contraceptives or the potential for enzyme alterations.

Effects of Other Drugs on CHCs
Effects of CHCs on Other Drugs
Interference with Laboratory Tests
  • The use of contraceptive steroids may influence the results of certain laboratory tests, such as coagulation factors, lipids, glucose tolerance, and binding proteins.

Use in Specific Populations

Pregnancy

Pregnancy Category (FDA):

  • There is little or no increased risk of birth defects in women who inadvertently use CHCs during early pregnancy. Epidemiologic studies and meta-analyses have not found an increased risk of genital or non-genital birth defects (including cardiac anomalies and limb-reduction defects) following exposure to low dose CHCs prior to conception or during early pregnancy.
  • The administration of CHCs to induce withdrawal bleeding should not be used as a test for pregnancy. CHCs should not be used during pregnancy to treat threatened or habitual abortion.


Pregnancy Category (AUS): There is no Australian Drug Evaluation Committee (ADEC) guidance on usage of Etonogestrel and Ethinyl Estradiol Vaginal Ring in women who are pregnant.

Labor and Delivery

There is no FDA guidance on use of Etonogestrel and Ethinyl Estradiol Vaginal Ring during labor and delivery.

Nursing Mothers

The effects of etonorgestrel and ethinyl estradiol vaginal ring in nursing mothers have not been evaluated and are unknown. When possible, advise the nursing mother to use other forms of contraception until she has completely weaned her child. CHCs can reduce milk production in breastfeeding mothers. This is less likely to occur once breastfeeding is well-established; however, it can occur at any time in some women. Small amounts of contraceptive steroids and/or metabolites are present in breast milk.

Pediatric Use

Safety and efficacy of etonorgestrel and ethinyl estradiol vaginal ring have been established in women of reproductive age. Efficacy is expected to be the same for postpubertal adolescents under the age of 18 and for users 18 years and older. Use of this product before menarche is not indicated.

Geriatic Use

Etonorgestrel and ethinyl estradiol vaginal ringhas not been studied in postmenopausal women and is not indicated in this population.

Gender

There is no FDA guidance on the use of Etonogestrel and Ethinyl Estradiol Vaginal Ring with respect to specific gender populations.

Race

There is no FDA guidance on the use of Etonogestrel and Ethinyl Estradiol Vaginal Ring with respect to specific racial populations.

Renal Impairment

The effect of renal impairment on the pharmacokinetics of etonorgestrel and ethinyl estradiol vaginal ring has not been studied.

Hepatic Impairment

The effect of hepatic impairment on the pharmacokinetics of etonorgestrel and ethinyl estradiol vaginal ring has not been studied. Steroid hormones may be poorly metabolized in patients with impaired liver function. Acute or chronic disturbances of liver function may necessitate the discontinuation of CHC use until markers of liver function return to normal.

Females of Reproductive Potential and Males

There is no FDA guidance on the use of Etonogestrel and Ethinyl Estradiol Vaginal Ring in women of reproductive potentials and males.

Immunocompromised Patients

There is no FDA guidance one the use of Etonogestrel and Ethinyl Estradiol Vaginal Ring in patients who are immunocompromised.

Mechanism of Action

Combination hormonal contraceptives act by suppression of gonadotropins.

Structure

NuvaRing (etonogestrel/ethinyl estradiol vaginal ring) is a non-biodegradable, flexible, transparent, colorless to almost colorless, combination contraceptive vaginal ring containing two active components, a progestin, etonogestrel (13-ethyl-17-hydroxy-11-methylene-18,19-dinor-17α-pregn-4-en-20-yn-3-one) and an estrogen, ethinyl estradiol (19-nor-17α-pregna-1,3,5(10)-trien-20-yne-3,17-diol). When placed in the vagina, each ring releases on average 0.120 mg/day of etonogestrel and 0.015 mg/day of ethinyl estradiol over a three-week period of use. NuvaRing is made of ethylene vinylacetate copolymers (28% and 9% vinylacetate) and magnesium stearate and contains 11.7 mg etonogestrel and 2.7 mg ethinyl estradiol. NuvaRing is not made with natural rubber latex. NuvaRing has an outer diameter of 54 mm and a cross-sectional diameter of 4 mm. The molecular weights for etonogestrel and ethinyl estradiol are 324.46 and 296.40, respectively. The structural formulas are as follows:

Pharmacodynamics

Although the primary effect of this action is inhibition of ovulation, other alterations include changes in the cervical mucus (which increase the difficulty of sperm entry into the uterus) and the endometrium (which reduce the likelihood of implantation).

Pharmacokinetics

  • Absorption:
This image is provided by the National Library of Medicine.
This image is provided by the National Library of Medicine.
This image is provided by the National Library of Medicine.
  • Prolonged use of etonogestrel and ethinyl estradiol vaginal ring: The mean serum etonogestrel concentration at the end of the fourth week of continuous use of etonogestrel and ethinyl estradiol vaginal ring was 1272 ± 311 pg/mL compared to a mean concentration range of 1578 ± 408 to 1374 ± 328 pg/mL at the end of weeks one to three. The mean serum ethinyl estradiol concentration at the end of the fourth week of continuous use of etonogestrel and ethinyl estradiol vaginal ring was 16.8 ± 4.6 pg/mL compared to a mean concentration range of 19.1 ± 4.5 to 17.6 ± 4.3 pg/mL at the end of weeks one to three.
  • Distribution:
  • Etonogestrel: Etonogestrel is approximately 32% bound to sex hormone-binding globulin (SHBG) and approximately 66% bound to albumin in blood.
  • Ethinyl estradiol: Ethinyl estradiol is highly but not specifically bound to serum albumin (98.5%) and induces an increase in the serum concentrations of SHBG.
  • Metabolism: In vitro data shows that both etonogestrel and ethinyl estradiol are metabolized in liver microsomes by the cytochrome P450 3A4 isoenzyme. Ethinyl estradiol is primarily metabolized by aromatic hydroxylation, but a wide variety of hydroxylated and methylated metabolites are formed. These are present as free metabolites and as sulfate and glucuronide conjugates. The hydroxylated ethinyl estradiol metabolites have weak estrogenic activity. The biological activity of etonogestrel metabolites is unknown.
  • Excretion: Etonogestrel and ethinyl estradiol are primarily eliminated in urine, bile and feces.
  • Drug Interactions:

Nonclinical Toxicology

In a 24-month carcinogenicity study in rats with subdermal implants releasing 10 and 20 mcg etonogestrel per day, (approximately 0.3 and 0.6 times the systemic steady-state exposure of women using etonogestrel and ethinyl estradiol vaginal ring), no drug-related carcinogenic potential was observed.Etonogestrel was not genotoxic in the in vitro Ames/Salmonella reverse mutation assay, the chromosomal aberration assay in Chinese hamster ovary cells or in the in vivo mouse micronucleus test. Fertility returned in rats after withdrawal from treatment.

Clinical Studies

  • In three large one-year clinical trials enrolling 2,834 women aged 18-40 years, in North America, Europe, Brazil, and Chile, the racial distribution was 93% Caucasian, 5.0% Black, 0.8% Asian, and 1.2% Other. Women with BMI ≥ 30 kg/m2 were excluded from these studies.
  • Based on pooled data from the three trials, 2,356 women aged < 35 years completed 23,515 evaluable cycles of etonogestrel and ethinyl estradiol vaginal ring use (cycles in which no back-up contraception was used). The pooled pregnancy rate (Pearl Index) was 1.28 (95% CI [0.8, 1.9]) per 100 women-years of etonogestrel and ethinyl estradiol vaginal ring use. In the US study, the Pearl Index was 2.02 (95% CI [1.1, 3.4]) per 100 women-years of etonogestrel and ethinyl estradiol vaginal ring use.

Patient Counseling Information

See FDA-approved patient labeling (Patient Information and Instructions for Use). Counsel patients regarding the following:

  • Cigarette smoking increases the risk of serious cardiovascular events from use of NuvaRing, and women who are over 35 years old and smoke should not use NuvaRing.
  • The increased risk of VTE compared to non-users of CHCs is greatest after initially starting a CHC or restarting (following a 4-week or greater CHC-free interval) the same or a different CHC.
  • Etonogestrel and ethinyl estradiol vaginal ring does not protect against HIV infection (AIDS) and other sexually transmitted infections.
  • The Warnings and Precautions associated with etonogestrel and ethinyl estradiol vaginal ring.
  • Etonogestrel and ethinyl estradiol vaginal ring is not to be used during pregnancy. If pregnancy is planned or occurs during treatment with etonogestrel and ethinyl estradiol vaginal ring, instruct the patient to discontinue etonogestrel and ethinyl estradiol vaginal ring use.
  • The proper usage of etonogestrel and ethinyl estradiol vaginal ring and what to do if she does not comply with the labeled timing of insertion and removal.
  • The need to use a barrier method of contraception when the ring is out for more than three continuous hours until etonogestrel and ethinyl estradiol vaginal ring has been used continuously for at least seven days.
  • The proper disposal of a used etonogestrel and ethinyl estradiol vaginal ring.
  • Use a back-up or alternative method of contraception when enzyme inducers are used with etonogestrel and ethinyl estradiol vaginal ring.
  • CHCs may reduce breast milk production. This is less likely to occur if breastfeeding is well established.
  • Women who start etonogestrel and ethinyl estradiol vaginal ring postpartum and have not yet had a normal period should use an additional non-hormonal method of contraception for the first seven days.
  • Amenorrhea may occur. Rule out pregnancy in the event of amenorrhea if etonogestrel and ethinyl estradiol vaginal ring has been out of the vagina for more than three consecutive hours, if the ring-free interval was extended beyond one week, if the woman has missed a period for two or more consecutive cycles, and if the ring has been retained for longer than four weeks.

Patient Information

What is the most important information I should know about NuvaRing?

Do not use NuvaRing if you smoke cigarettes and are over 35 years old. Smoking increases your risk of serious cardiovascular side effects (heart and blood vessel problems) from combination hormonal contraceptives (CHCs), including death from heart attack, blood clots or stroke. This risk increases with age and the number of cigarettes you smoke.

Hormonal birth control methods help to lower the chances of becoming pregnant. They do not protect against HIV infection (AIDS) and other sexually transmitted infections.

What is NuvaRing?

NuvaRing (NEW-vah-ring) is a flexible birth control vaginal ring used to prevent pregnancy. NuvaRing contains a combination of a progestin and estrogen, 2 kinds of female hormones. Birth control methods that contain both an estrogen and a progestin are called combination hormonal contraceptives (CHCs).

How well does NuvaRing work?

Your chance of getting pregnant depends on how well you follow the directions for using NuvaRing. The better you follow the directions, the less chance you have of getting pregnant. Based on the results of a US clinical study, approximately 1 to 3 women out of 100 women may get pregnant during the first year they use NuvaRing. The following chart shows the chance of getting pregnant for women who use different methods of birth control. Each box on the chart contains a list of birth control methods that are similar in effectiveness. The most effective methods are at the top of the chart. The box on the bottom of the chart shows the chance of getting pregnant for women who do not use birth control and are trying to get pregnant.

Who should not use NuvaRing?

Do not use NuvaRing if you:

  • Smoke and are over 35 years old
  • Have or have had blood clots in your arms, legs, eyes or lungs
  • Have an inherited problem with your blood that makes it clot more than normal
  • Have had a stroke
  • Have had a heart attack
  • Have certain heart valve problems or heart rhythm problems that can cause blood clots to form in the heart
  • Have high blood pressure that medicine can't control
  • Have diabetes with kidney, eye, nerve, or blood vessel damage
  • Have certain kinds of severe migraine headaches with aura, numbness, weakness, or changes in vision, or have any migraine headaches if you are over age 35
  • Have liver disease, including liver tumors
  • Have unexplained vaginal bleeding
  • Are pregnant or think you may be pregnant. NuvaRing is not for pregnant women.
  • Have or have had breast cancer or any cancer that is sensitive to female hormones
  • Are allergic to etonogestrel, ethinyl estradiol or any of the ingredients in NuvaRing. See the list of ingredients in NuvaRing at the end of this leaflet.

Hormonal birth control methods may not be a good choice for you if you have ever had jaundice (yellowing of the skin or eyes) caused by pregnancy or related to previous use of hormonal birth control.

Tell your healthcare provider if you have ever had any of the conditions listed above. Your healthcare provider can suggest another method of birth control.

What should I tell my healthcare provider before using NuvaRing?

Before you use NuvaRing tell your healthcare provider if you:

  • Have any medical conditions
  • Smoke
  • Are pregnant or think you are pregnant
  • Recently had a baby
  • Recently had a miscarriage or abortion
  • Have a family history of breast cancer
  • Have or have had breast nodules, fibrocystic disease, an abnormal breast x-ray, or abnormal mammogram
  • Use tampons and have a history of toxic shock syndrome
  • Have been diagnosed with depression
  • Have had liver problems including jaundice during pregnancy
  • Have or have had elevated cholesterol or triglycerides
  • Have or have had gallbladder, liver, heart, or kidney disease
  • Have diabetes
  • Have a history of jaundice (yellowing of the skin or eyes) caused by pregnancy (also called cholestasis of pregnancy)
  • Have a history of scanty or irregular menstrual periods
  • Have any condition that makes the vagina become irritated easily
  • Have or have had high blood pressure
  • Have or have had migraines or other headaches or seizures
  • Are scheduled for surgery. NuvaRing may increase your risk of blood clots after surgery. You should stop using NuvaRing at least 4 weeks before you have surgery and not restart it until at least 2 weeks after your surgery.
  • Are scheduled for any laboratory tests. Certain blood tests may be affected by hormonal birth control methods.
  • Are breastfeeding or plan to breastfeed. Hormonal birth control methods that contain estrogen, like NuvaRing, may decrease the amount of milk you make. A small amount of hormones from NuvaRing may pass into your breast milk. Consider another non-hormonal method of birth control until you are ready to stop breastfeeding.
Tell your healthcare provider about all medicines and herbal products you take, including prescription and over-the-counter medicines, vitamins and herbal supplements

Some medicines and herbal products may make hormonal birth control less effective, including, but not limited to:

  • Certain anti-seizure medicines (such as barbiturates, carbamazepine, felbamate, oxcarbazepine, phenytoin, rufinamide, topiramate)
  • Medicine to treat fungal infections (griseofulvin)
  • Certain combinations of HIV medicines, (such as nelfinavir, ritonavir, darunavir/ritonavir, (fos)amprenavir/ritonavir, lopinavir/ritonavir, and tipranavir/ritonavir)
  • Certain hepatitis C (HCV) medicines (such as boceprevir, telaprevir)
  • Non-nucleoside reverse transcriptase inhibitors (such as nevirapine)
  • Medicine to treat tuberculosis (such as rifampicin and rifabutin)
  • Medicine to treat high blood pressure in the vessels of the lung (bosentan)
  • Medicine to treat chemotherapy-induced nausea and vomiting (aprepitant)
  • St John's wort

Use an additional birth control method (such as a male condom with spermicide) when you take medicines that may make NuvaRing less effective. Continue back-up birth control for 28 days after stopping the medicine to help prevent you from becoming pregnant.

Some medicines and grapefruit juice may increase the level of ethinyl estradiol in your blood if used together, including:

  • The pain reliever acetaminophen
  • Ascorbic acid (vitamin C)
  • Medicines that affect how your liver breaks down other medicines (such as itraconazole, ketoconazole, voriconazole, and fluconazole)
  • Certain HIV medicines (atazanavir/ritonavir, indinavir)
  • Non-nucleoside reverse transcriptase inhibitors (such as etravirine)
  • Medicines to lower cholesterol such as atorvastatin and rosuvastatin

Hormonal birth control methods may interact with lamotrigine, a medicine used for seizures. This may increase the risk of seizures, so your healthcare provider may need to adjust your dose of lamotrigine.

Women on thyroid replacement therapy may need increased doses of thyroid hormone.

Ask your healthcare provider if you are not sure if you take any of the medicines listed above. Know the medicines you take. Keep a list of them to show your doctor and pharmacist when you get a new medicine.

  • How should I use NuvaRing?
  • Read the Instructions for Use at the end of this Patient Information that comes with your NuvaRing for information about the right way to use NuvaRing.
  • Use NuvaRing exactly as your healthcare provider tells you to use it.
  • NuvaRing is used in a 4 week cycle.
  • Insert 1 NuvaRing in the vagina and keep it in place for 3 weeks (21 days).
  • Remove the NuvaRing for a 1 week break (7 days). During the 1-week break (7 days), you will usually have your menstrual period.
Note: Insert and remove NuvaRing on the same day of the week and at the same time:
  • For example, if you insert your NuvaRing on a Monday at 8:00 am, you should remove it on the Monday 3 weeks later at 8:00 am.
  • After your 1 week (7 days) break, you should insert a new NuvaRing on the next Monday at 8:00 am.
  • While using NuvaRing, you should not use a vaginal diaphragm as your back-up method of birth control because NuvaRing may interfere with the correct placement and position of a diaphragm.
  • Use of spermicides or vaginal yeast products will not make NuvaRing less effective at preventing pregnancy.
  • Use of tampons will not make NuvaRing less effective or stop NuvaRing from working.
  • If NuvaRing has been left inside your vagina for more than 4 weeks (28 days), you may not be protected from pregnancy and you should see your healthcare provider to be sure you are not pregnant. Until you know the results of your pregnancy test, you should use an extra method of birth control, such as male condoms with spermicide, until the new NuvaRing has been in place for 7 days in a row.
  • Do not use more than 1 NuvaRing at a time. Too much hormonal birth control medicine in your body may cause nausea, vomiting, or vaginal bleeding.

Your healthcare provider should examine you at least 1 time a year to see if you have any signs of side effects from using NuvaRing.

What are the possible side effects of using NuvaRing?
NuvaRing may cause serious side effects, including
  • Blood clots: Like pregnancy, combination hormonal birth control methods increase the risk of serious blood clots (see following graph), especially in women who have other risk factors, such as smoking, obesity, or age greater than 35. This increased risk is highest when you first start using a combination hormonal birth control method or when you restart the same or different combination hormonal birth control method after not using it for a month or more. Talk with your healthcare provider about your risk of getting a blood clot before using NuvaRing or before deciding which type of birth control is right for you.
  • In some studies of women who used NuvaRing, the risk of getting a blood clot was similar to the risk in women who used combination birth control pills.
  • Other studies have reported that the risk of blood clots was higher for women who use combination birth control pills containing desogestrel (a progestin similar to the progestin in NuvaRing) than for women who use combination birth control pills that do not contain desogestrel.
  • It is possible to die or be permanently disabled from a problem caused by a blood clot, such as heart attack or stroke. Some examples of serious blood clots are blood clots in the:
  • Legs (deep vein thrombosis)
  • Lungs (pulmonary embolus)
  • Eyes (loss of eyesight)
  • Heart (heart attack)
  • Brain (stroke)

To put the risk of developing a blood clot into perspective: If 10,000 women who are not pregnant and do not use hormonal birth control are followed for one year, between 1 and 5 of these women will develop a blood clot. The figure below shows the likelihood of developing a serious blood clot for women who are not pregnant and do not use hormonal birth control, for women who use hormonal birth control, for pregnant women, and for women in the first 12 weeks after delivering a baby.

General information about the safe and effective use of NuvaRing

Medicines are sometimes prescribed for purposes other than those listed in the Patient Information. Do not use NuvaRing for a condition for which it was not prescribed. Do not give NuvaRing to other people. It may harm them.

This leaflet summarizes the most important information about NuvaRing. If you would like more information, talk with your healthcare provider. You can ask your pharmacist or healthcare provider for information about NuvaRing that is written for health professionals.

For more information, go to www.nuvaring.com or call 1-877-NUVARING (1-877-688-2746).

What are the ingredients in NuvaRing?
  • Active ingredients: etonogestrel and ethinyl estradiol
  • Inactive ingredients: ethylene vinylacetate copolymers (28% and 9% vinylacetate) and magnesium stearate.

NuvaRing is not made with natural rubber latex.

Do Hormonal Birth Control Methods Cause Cancer?

Hormonal birth control methods do not seem to cause breast cancer. However, if you have breast cancer now or have had it in the past, do not use hormonal birth control, including NuvaRing, because some breast cancers are sensitive to hormones.

Women who use hormonal birth control methods may have a slightly higher chance of getting cervical cancer. However, this may be due to other reasons such as having more sexual partners.

What should I know about my period when using NuvaRing?

When you use NuvaRing you may have bleeding and spotting between periods, called unplanned bleeding. Unplanned bleeding may vary from slight staining between menstrual periods to breakthrough bleeding, which is a flow much like a regular period. Unplanned bleeding occurs most often during the first few months of NuvaRing use, but may also occur after you have been using NuvaRing for some time. Such bleeding may be temporary and usually does not indicate any serious problems. It is important to continue using the ring on schedule. If the unplanned bleeding or spotting is heavy or lasts for more than a few days, you should discuss this with your healthcare provider.

What if I miss my regular scheduled period when using NuvaRing?

Some women miss periods on hormonal birth control, even when they are not pregnant. Consider the possibility that you may be pregnant if:

  1. you miss a period and NuvaRing was out of the vagina for more than 3 hours during the 3 weeks (21 days) of ring use
  2. you miss a period and waited longer than 1 week to insert a new ring
  3. you have followed the instructions and you miss 2 periods in a row
  4. you have left NuvaRing in place for longer than 4 weeks (28 days)
What if I want to become pregnant?

You may stop using NuvaRing whenever you wish. Consider a visit with your healthcare provider for a pre-pregnancy checkup before you stop using NuvaRing.

Instructions for Use

Etonogestrel/ethinyl estradiol vaginal ring

Read these Instructions for Use before you start using NuvaRing and each time you get a refill. There may be new information. This information does not take the place of talking to your healthcare provider about your treatment.

How should I start using NuvaRing?

If you are not currently using hormonal birth control, you have 2 ways to start using NuvaRing. Choose the best way for you:

  • First Day Start: Insert NuvaRing on the first day of your menstrual period. You will not need to use another birth control method since you are using NuvaRing on the first day of your menstrual period.
  • Day 2 to Day 5 Cycle Start: You may choose to start NuvaRing on days 2 to 5 of your menstrual period. Make sure you also use an extra method of birth control (barrier method), such as male condoms with spermicide for the first 7 days of NuvaRing use in the first cycle.
If you are changing from a birth control pill or patch to NuvaRing

If you have been using your birth control method correctly and are certain that you are not pregnant, you can change to NuvaRing any day. Do not start NuvaRing any later than the day you would start your next birth control pill or apply your patch.

If you are changing from a progestin-only birth control method, such as a minipill, implant or injection or from an intrauterine system (IUS)
  • You may switch from a minipill on any day. Start using NuvaRing on the day that you would have taken your next minipill.
  • You should switch from an implant or the IUS and start using NuvaRing on the day that you remove the implant or IUS
  • You should switch from an injectable and start using NuvaRing on the day when your next injection would be due.

If you are changing from a minipill, implant or injection or from an intrauterine system (IUS), you should use an extra method of birth control, such as a male condom with spermicide during the first 7 days of using NuvaRing.

If you start using NuvaRing after an abortion or miscarriage
  • Following a first trimester abortion or miscarriage: You may start NuvaRing within 5 days following a first trimester abortion or miscarriage (the first 12 weeks of pregnancy). You do not need to use an additional birth control method.
  • If you do not start NuvaRing within 5 days after a first trimester abortion or miscarriage, use a non-hormonal birth control method, such as male condoms and spermicide, while you wait for your period to start. Begin NuvaRing at the time of your next menstrual period. Count the first day of your menstrual period as "Day 1" and start NuvaRing one of the following 2 ways below.
  • First Day Start: Insert NuvaRing on the first day of your menstrual period. You will not need to use another birth control method since you are using NuvaRing on the first day of your menstrual period.
  • Day 2 to Day 5 Cycle Start: You may choose to start NuvaRing on Days 2 to 5 of your menstrual period. Make sure you also use an extra method of birth control (barrier method), such as male condoms with spermicide for the first 7 days of NuvaRing use in the first cycle.
  • Following a second trimester abortion or miscarriage: You may start using NuvaRing no sooner than 4 weeks (28 days) after a second trimester abortion (after the first 12 weeks of pregnancy).
If you are starting NuvaRing after childbirth
  • You may start using NuvaRing no sooner than 4 weeks (28 days) after having a baby if you are not breastfeeding.
  • If you have not gotten your menstrual period after childbirth, you should talk to your healthcare provider. You may need a pregnancy test to make sure you are not pregnant before you start using NuvaRing.
  • Use another birth control method such as male condoms with spermicide for the first 7 days in addition to NuvaRing.

If you are breastfeeding you should not use NuvaRing. Use other birth control methods until you are no longer breastfeeding

Step 1. Choose a position for insertion of NuvaRing

Choose the position that is comfortable for you. For example, lying down, squatting, or standing with 1 leg up

Step 2. Open the pouch to remove your NuvaRing
  • Each NuvaRing comes in a re-sealable foil pouch.
  • Wash and dry your hands before removing NuvaRing from the foil pouch.
  • Open the foil pouch at either notch near the top.
  • Keep the foil pouch so you can place your used NuvaRing in it before you throw it away in your household trash.
Step 3. Prepare NuvaRing for insertion
  • Hold NuvaRing between your thumb and index finger and press the sides of the ring together
This image is provided by the National Library of Medicine.
Step 4. Insert NuvaRing into your vagina
  • Insert the folded NuvaRing into your vagina and gently push it further up into your vagina using your index finger (See Figure F and G).
  • When you insert NuvaRing it may be in different positions in your vagina, but NuvaRing does not have to be in an exact position for it to work (See Figure H and I).
  • NuvaRing may move around slightly within your vagina. This is normal. Although some women may be aware of NuvaRing in the vagina, most women do not feel it when it is in place.
This image is provided by the National Library of Medicine.

Inserting NuvaRing (Figure F, Figure G) and positioning NuvaRing (Figure H, Figure I) Note:

  • If the NuvaRing feels uncomfortable, you may not have pushed the ring into your vagina far enough. Use your finger to gently push the NuvaRing as far as you can into your vagina. There is no danger of NuvaRing being pushed too far up in the vagina or getting lost (See Figure G).
  • Some women have accidently inserted NuvaRing into their bladder. If you have pain during or after insertion and you cannot find NuvaRing in your vagina, call your healthcare provider right away.
Step 5. How do I remove NuvaRing?

Wash and dry your hands. Choose the position that is most comfortable for you (See Figures A, B, and C). Put your index finger into your vagina and hook it through the NuvaRing. Gently pull downward and forward to remove the NuvaRing and pull it out (See Figure J).

This image is provided by the National Library of Medicine.
Step 6. Throw away the used NuvaRing

Place the used NuvaRing in the re-sealable foil pouch and put it in a trash can out of the reach of children and pets. Do not throw NuvaRing in the toilet.

What else should I know about using NuvaRing?
What If I leave NuvaRing in too long?
  • If you leave NuvaRing in your vagina for up to 4 weeks (28 days) you will still be getting pregnancy protection. Remove your old NuvaRing for 1 week (7 days) and insert a new NuvaRing 1 week (7 days) later (See Steps 1 through 4).
  • If you leave NuvaRing in your vagina longer than 4 weeks (28 days), remove the ring and check to make sure you are not pregnant.
  • If you are not pregnant, insert a new NuvaRing (See Steps 1 through 4). You must use another birth control method, such as male condoms with spermicide, until the new NuvaRing has been used for 7 days in a row.
What should I do if my NuvaRing comes out of my vagina?

NuvaRing can slip or accidentally come out (expelled) of your vagina during sexual intercourse, bowel movements, use of tampons, or if it breaks.

  • NuvaRing may break causing the ring to lose its shape. If the ring stays in your vagina this should not lower NuvaRing's effectiveness at preventing pregnancy.
  • If NuvaRing breaks and slips out of your vagina, throw the broken ring in your household trash out of the reach of children and pets.
  • Insert a new NuvaRing (See Steps 1 through 4).
  • You should pay attention when removing a tampon to be sure that your NuvaRing is not accidentally pulled out.
  • Be sure to insert NuvaRing before inserting a tampon.
  • If you accidentally pull out your NuvaRing while using tampons, rinse your NuvaRing in cool to lukewarm (not hot) water and insert it again right away.
  • NuvaRing can be pushed out of (expelled from) your vagina during sexual intercourse or during a bowel movement.
  • If the expelled ring has been left out of your vagina for less than 3 hours, rinse the expelled NuvaRing in cool to lukewarm (not hot) water and insert it again right away.
  • If the expelled NuvaRing has been out of your vagina for more than 3 hours, insert a new NuvaRing as soon as you remember (See Step 1 thru Step 4).
  • During Weeks 1 and 2 after you have inserted your new NuvaRing, you may not be protected from pregnancy. You should use another birth control method, such as male condoms with spermicide, until the ring has been in place for 7 days in a row.
  • At the end of Week 3: you should remove the NuvaRing and throw it away in your household trash away from children and pets and follow one of the two options below:
  • Option 1: Insert a new ring right away to start your 21 Day NuvaRing use cycle. You may not have your regular period but you may have spotting or vaginal bleeding.
  • Option 2: Insert a new ring no later than 7 days, from the time the previous ring was removed or expelled. During this time, you may have your period.
Note: You should only choose to do option 2 if you used NuvaRing for 7 days in a row, prior to the day that your previous NuvaRing was accidently removed or expelled.
With either option 1 or 2, you should use another birth control method such as male condoms with spermicides until the new NuvaRing has been used for 7 days in a row.

This Patient Information and Instructions for Use have been approved by the U.S. Food and Drug Administration.
