Follow all your doctor's treatment orders. Even if the symptoms go away, you still need to finish treatment. If symptoms continue after treatment, see your doctor. Avoid any sexual activity while you are being treated for syphilis. Don't have sexual contact until the syphilis sores are completely healed. Tell your sex partner(s). Your sex partner(s) should get tested for syphilis and treated if needed. After you have completed treatment for syphilis, get retested after 6 months and 12 months. Some doctors recommend more frequent follow-up tests. Get tested for HIV. If your test result is negative, ask your doctor if you need to be retested and when. Once you have been treated and cured, take steps to lower your risk from getting syphilis again.
