Syphilis Treatment

Treatment for syphilis includes antibiotics and acetaminophen or nonsteroidal anti-inflammatory medications for pain and fever. Penicillin is considered to be the treatment of choice for treating syphilis. The CDC recommends that those who are allergic to penicillin undergo penicillin allergy skin testing and desensitization (followed by treatment with penicillin).

The penicillin dosing and schedule differs with the stage of the disease. Primary and secondary stage syphilis can be treated with a single dose of benzathine penicillin G (2.4 million units IM). Later stages require multiple doses delivered over weeks.

Treatment for syphilis includes:


Jarisch-Herxheimer Reaction
A known complication of antibiotic therapy is the Jarisch-Herxheimer reaction. This is represented by the onset of muscle aches, fever, headache, and a rapid pulse. The rash or chancre may even appear to worsen. The Jarisch-Herxheimer reaction is due to an inflammatory molecule that is released by the dying treponemes (syphilis bacteria). The reaction commonly develops within several hours of antibiotic dosing, but usually clears within 24 hours of onset.
