Syphilis treatment requires clinician-directed testing and antibiotics, even when symptoms are mild or absent. Syphilis is a bacterial infection that can be treated with the right antibiotic chosen by a clinician. Testing and treatment should not be delayed: symptoms can be mild or disappear while infection remains. Do not self-treat; partners may also need evaluation.

01Syphilis treatment starts with testing and assessment
A painless sore may appear first, followed later by rash, including on palms or soles, swollen glands or flu-like symptoms. Some people have no noticeable symptoms. A sore or rash alone cannot confirm syphilis.
02Testing and clinical assessment
Blood tests are commonly used, sometimes alongside examination of a lesion. Test interpretation can depend on prior treatment and timing. Tell the clinician about symptoms, possible exposure and any previous syphilis treatment.
03Treatment and follow-up
A clinician selects antibiotic treatment based on stage, history and pregnancy status where relevant. Do not use leftover antibiotics. Follow-up blood testing may be needed to check response, and recent partners may need testing or treatment.
04Preventing onward transmission
Avoid sexual contact until a clinician advises it is safe and any sores have healed. Use barriers to reduce STI risk, while understanding they do not eliminate every transmission route.
05Symptoms can change over time
Syphilis can cause a painless sore, rash or other symptoms, but signs may be subtle or absent. Symptoms can resolve without the infection being treated. If exposure is possible or a partner has tested positive, seek a qualified clinical assessment rather than waiting for a visible symptom.
06Testing and diagnosis need context
A clinician may recommend blood tests and ask about prior results or treatment. Some people need repeat testing depending on when exposure occurred and which test is used. Tell the clinician about pregnancy possibility, allergies and prior antibiotics. Do not interpret one result without the testing service’s explanation.
07Use the prescribed treatment plan
Syphilis is treated with clinician-selected antibiotics. The medicine and follow-up depend on stage, history, pregnancy and other factors. Do not use leftover antibiotics or stop a prescribed course without advice. If you have a severe allergy or a reaction after treatment, contact a clinician promptly.
08Plan partner communication and follow-up
Ask when to repeat blood tests, when sexual activity can resume and whether partners should be informed or tested. If pregnant or possibly pregnant, seek prompt medical care because treatment timing matters for the pregnant person and baby. Ask the clinic how confidentiality is managed.
09How long syphilis takes to cure, and which doctor to see
How long does it take to cure syphilis? Early syphilis is often treated with a single injection; later stages may need three weekly doses. Blood tests are repeated over months to confirm the response. What does syphilis look like? Usually a single painless sore first, then a rash that can involve the palms and soles. An STD specialist or venereologist treats syphilis — see which doctor to consult for STD and can STDs be cured?
