Syphilis is easy to cure in its early stages. Penicillin, an antibiotic, injected into the muscle is the best treatment for syphilis. If you are allergic to penicillin, your health care provider may give you another antibiotic to take by mouth.
If you have neurosyphilis, you may need to receive daily doses of penicillin intravenously (in the vein) and may need to be treated in the hospital.
If you have late syphilis, damage done to your body organs cannot be reversed.
While you are being treated, you should abstain from sex until your sores are completely healed. You should also notify your sex partners so they can be tested for syphilis and treated if necessary.
