Question: how long does a recurrent herpes outbreak last with acyclovir?
Answer: Genital herpes outbreaks may be treated for 3–5 days with oral antiviral drugs, including acyclovir (ACV), valacyclovir (Valtrex; GlaxoSmithKline), and famciclovir (Famvir; Novartis), but treatment only decreases the duration of symptoms by approximately one-quarter [3, 4].
