Overview
Parenteral penicillin G has been an effective regimen to achieve clinical resolution and to prevent late sequelae of syphilis.
Management for Primary and Secondary Syphilis
- Penicillin G is effectively used to achieve clinical resolution and to prevent late sequeale.[1]
- Additional doses of benzathine penicillin G, amoxicillin, or other antibiotics are not known to enhance efficacy of the recommended regimen in the management of primary and secondary, regardless of HIV status.

Other Management Considerations
HIV Infection
- All persons who have syphilis should be tested for HIV infection.
- In geographic areas in which the prevalence of HIV is high, persons who have primary syphilis should be retested for HIV after 3 months if the first HIV test result was negative.
Neurosyphilis
- Patients who have syphilis and symptoms or signs suggesting neurologic disease (e.g., meningitis and hearing loss) or signs of ocular syphilis (e.g., uveitis, iritis, neuroretinitis, and optic neuritis) should have an evaluation that includes CSF analysis, thorough cranial nerve examination, ocular slit-lamp and ophthalmologic examination. Treatment should be guided by the results of this evaluation.
- Invasion of CSF by T. pallidum accompanied by CSF laboratory abnormalities is common among adults who have primary or secondary syphilis.[3] Therefore, in the absence of clinical neurologic findings, no evidence exists to support variation from the recommended treatment regimen for early syphilis.
- Symptomatic neurosyphilis develops in only a limited number of persons after treatment with the penicillin regimens recommended for primary and secondary syphilis. Therefore, unless clinical signs or symptoms of neurologic or ophthalmic involvement are present or treatment failure is documented, routine CSF analysis is not recommended for persons who have primary or secondary syphilis.
Special Considerations
Penicillin Allergy: Alternative Regimen
- Data to support the use of alternatives to penicillin in the treatment of early syphilis are limited. However, several therapies may be effective in non-pregnant, penicillin-allergic patients who have primary or secondary syphilis.
- Doxycycline 100 mg orally twice daily for 14 days[4][5] and tetracycline (500 mg four times daily for 14 days) are regimens that have been used for many years.
- Compliance is likely to be better with doxycycline than tetracycline, because tetracycline can cause gastrointestinal side effects.
- Clinical studies, though limited, along with biologic and pharmacologic evidence suggest that ceftriaxone (1 g daily either IM or IV for 10-14 days) is effective for treating early syphilis; the optimal dose and duration of ceftriaxone therapy have not been defined.[6]
- Azithromycin as a single 2-g oral dose is effective for treating early syphilis.[7][8][9] However, T. pallidum chromosomal mutations associated with azithromycin resistance and treatment failures have been documented in several geographical areas in the United States.[10][11] As such, the use of azithromycin should be used with caution only when treatment with penicillin or doxycycline is not feasible. Azithromycin should not be used in MSM or pregnant women.
- Close follow-up of persons receiving any alternative therapies is essential.
- Persons with a penicillin allergy whose compliance with therapy or follow-up cannot be ensured should be desensitized and treated with benzathine penicillin.
- Skin testing for penicillin allergy may be useful in some circumstances in which the reagents and expertise are available to perform the test adequately.
Pregnancy
Pregnant patients who are allergic to penicillin should be desensitized and treated with penicillin.
Follow-Up
- Treatment failure can occur with any regimen. However, assessing response to treatment frequently is difficult, and definitive criteria for cure or failure have not been established.
- Nontreponemal test titers may decline more slowly for persons who previously had syphilis.[12][13]
- Patients who have signs or symptoms that persist or recur or who have a sustained fourfold increase in nontreponemal test titer (i.e. compared with the maximum or baseline titer at the time of treatment) probably failed treatment or were reinfected. These patients should be retreated and reevaluated for HIV infection.
- Because treatment failure usually cannot be reliably distinguished from reinfection with T. pallidum, a CSF analysis also should be performed.
- Failure of nontreponemal test titers to decline fourfold within 6-12 months after therapy for primary or secondary syphilis may be indicative of treatment failure.
- Clinical trial data have demonstrated that greater than 15% of patients with early syphilis treated with the recommended therapy will not achieve the two dilution decline in nontreponemal titer used to define response at 1 year after treatment.[14]
- Persons whose titers do not decline should be reevaluated for HIV infection.
- Optimal management of such patients is unclear.
- If additional follow-up cannot be ensured, retreatment is recommended.
- Because treatment failure may be the result of unrecognized CNS infection, CSF examination can be considered in such situations.
- For retreatment, weekly injections of benzathine penicillin G 2.4 million units IM for 3 weeks is recommended, unless CSF examination indicates that neurosyphilis is present.
- In rare instances, serologic titers do not decline despite a negative CSF examination and a repeated course of therapy. In these circumstances, the need for additional therapy or repeated CSF examinations is unclear, but is not generally recommended.
