Use in Specific Populations

Pregnancy

Pregnancy Category (FDA): B

• Teratology and peri- and post-natal studies have been conducted with emedastine difumarate in rats and rabbits. At 15,000 times the maximum recommended ocular human use level, emedastine difumarate was shown not to be teratogenic in rats and rabbits and no effects on peri/post-natal development were observed in rats. However, at 70,000 times the maximum recommended ocular human use level, emedastine difumarate was shown to increase the incidence of external, visceral and skeletal anomalies in rats. There are, however, no adequate and well controlled studies in pregnant women. Because animal studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.

Pregnancy Category (AUS):

• Australian Drug Evaluation Committee (ADEC) Pregnancy Category

There is no Australian Drug Evaluation Committee (ADEC) guidance on usage of Emedastine Difumarate in women who are pregnant.

Labor and Delivery

There is no FDA guidance on use of Emedastine Difumarate during labor and delivery.

Nursing Mothers

Emedastine has been identified in breast milk in rats following oral administration. It is not known whether topical ocular administration could result in sufficient systemic absorption to produce detectable quantities in breast milk. Nevertheless, caution should be exercised when EMADINE® (emedastine difumarate ophthalmic solution) 0.05% is administered to a nursing mother.

Pediatric Use

Safety and effectiveness in pediatric patients below the age of 3 years have not been established.

Geriatic Use

No overall differences in safety or effectiveness have been observed between elderly and younger patients.

Gender

There is no FDA guidance on the use of Emedastine Difumarate with respect to specific gender populations.

Race

There is no FDA guidance on the use of Emedastine Difumarate with respect to specific racial populations.

Renal Impairment

There is no FDA guidance on the use of Emedastine Difumarate in patients with renal impairment.

Hepatic Impairment

There is no FDA guidance on the use of Emedastine Difumarate in patients with hepatic impairment.

Females of Reproductive Potential and Males

There is no FDA guidance on the use of Emedastine Difumarate in women of reproductive potentials and males.

Immunocompromised Patients

There is no FDA guidance one the use of Emedastine Difumarate in patients who are immunocompromised.

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, Impairment of Fertility: Emedastine difumarate demonstrated no carcinogenicity effects in lifetime studies in mice and rats at dietary doses more than 80,000 times and more than 26,000 times the maximum recommended ocular human use level of 0.002 mg/kg/day for a 50 kg adult, respectively. Higher dose levels were not tested. Emedastine difumarate was determined to be nonmutagenic in an in vitro bacterial reverse mutation (Ames) test, an in vitro modification of the Ames test, an in vitro mammalian chromosome aberration test, an in vitro mammalian forward mutation test, an in vitro mammalian DNA repair synthesis test, an in vivo mammalian sister chromatid exchange test and an in vivo mouse micronucleus test. There was no evidence of impaired fertility or reproductive capacity in rats at 15,000 times the maximum recommended ocular human use level.
