Frequently asked questions

Do antivirals cure herpes?

They do not remove the virus for good, but they shorten outbreaks, ease symptoms and can reduce how often attacks happen.

Why start antivirals early?

They work best in the first day or two of symptoms, before the virus multiplies, so starting promptly matters.
