There is no cure for genital herpes, but there are medications that can help with managing it. One of these antiviral drugs, Aciclovir, is most commonly used to reduce the severity of the first outbreak. It works by preventing the virus from multiplying, reducing the length and severity of the outbreak. Doctors are unlikely to prescribe Aciclovir, however, if the outbreak is mild or has mostly healed by the time they see the patient. Most people are able to manage outbreaks with lifestyle changes and other at-home care.
