What to expect from antibiotic treatment for syphilis

The antibiotic and schedule depend on the stage of syphilis, your symptoms, pregnancy status, allergy history, and whether the nervous system or eyes may be involved. Treatment may involve an injection or another prescribed regimen. A short-lived fever, chills, headache, or muscle aches can occur soon after treatment as the body reacts to the dying bacteria; tell the treating team if symptoms are severe or worrying.

Treatment stops the infection from progressing, but it may not reverse damage that occurred before treatment. Blood tests are used over time to check the response, so keep every follow-up appointment even when you feel well.

Follow the dosing plan exactly and tell the clinic about any allergy symptoms. Avoid sexual contact until your clinician confirms it is safe, and discuss recent partners so they can be tested or treated. Use condoms consistently afterward to reduce the chance of acquiring or passing on an infection. Tell the clinician promptly if you are pregnant or might be pregnant.

Get emergency help for breathing difficulty, facial or throat swelling, collapse, or widespread blistering after treatment. Seek prompt specialist assessment for new vision changes, severe eye pain, hearing changes, weakness, confusion, or a severe headache. Return to the clinic if sores, rash, or other symptoms persist or return.

Which stage is being treated? What follow-up blood tests are needed and when? When can sexual activity resume, and how will partner notification be handled confidentially?
