How is syphilis treated?
Penicillin (an antibiotic) is the preferred drug to treat syphilis at all stages. The dose and length of treatment depends on the stage of syphilis and symptoms of the disease. For people who are allergic to penicillin, other drugs might work during the first and second stages. But they cannot be used by pregnant women. In late syphilis, treatment will prevent further harm, but damage already done to body organs cannot be reversed. Treatment does not protect you from getting syphilis again. You can get syphilis again after being cured if you are exposed to it.
