Overview
Penicillin G, administered parenterally, is the preferred drug for treating all stages of syphilis. If allergic, then tetracycline or doxycycline may also be used. During pregnancy, parenteral penicillin G is the only therapy with documented efficacy for syphilis.
Medical Therapy
- Penicillin G, administered parenterally, is the preferred drug for treating all stages of syphilis.
- The preparation used (i.e., benzathine, aqueous procaine, or aqueous crystalline), the dosage, and the length of treatment depend on the stage and clinical manifestations of the disease.
- Selection of the appropriate penicillin preparation is important, because T. pallidum can reside in sequestered sites (e.g., the CNS and aqueous humor) that are poorly accessed by some forms of penicillin.
- Combinations of benzathine penicillin, procaine penicillin, and oral penicillin preparations are not considered appropriate for the treatment of syphilis.
- During pregnancy, parenteral penicillin G is the only therapy with documented efficacy for syphilis. Pregnant women with syphilis in any stage who report penicillin allergy should be desensitized and treated with penicillin
- The Jarisch-Herxheimer reaction is an acute febrile reaction
- Patients should be informed about this possible adverse reaction.
- The Jarisch-Herxheimer reaction occurs most frequently among patients who have early syphilis, presumably because bacterial burdens are higher during these stages.
- Antipyretics can be used to manage symptoms, but they have not been proven to prevent this reaction.
- The Jarisch-Herxheimer reaction might induce early labor or cause fetal distress in pregnant women, but this should not prevent or delay therapy.

When possible, a full 10-day course of penicillin is preferred, even if ampicillin was initially provided for possible sepsis.

- Note: If the mother has untreated early syphilis at delivery, 10 days of parenteral therapy can be considered
- 4.3 condition3: Infants who have a normal physical examination and a serum quantitative nontreponemal serologic titer the same or less than fourfold the maternal titer and the (1) mother was treated during pregnancy, treatment was appropriate for the stage of infection, and treatment was administered >4 weeks before delivery and (2) mother has no evidence of reinfection or relapse.
