When is Acyclovir most effective?

When is Acyclovir most effective?

• A. Only during chronic suppression
• B. Only if combined with antibiotics
• C. When it is the individual's first outbreak of HSV
• D. During months 2-3 after outbreak

Answer: (C)

Acyclovir is most effective when started at the onset of the first HSV outbreak because this is when viral replication is high and there’s no preexisting immune memory to control it. Initiating treatment early during the initial episode shortens the course of lesions, reduces pain, lowers viral shedding, and decreases transmission risk more than if you start later. In later outbreaks, the immune system has learned to respond, so the same therapy tends to have a smaller impact. Suppression therapy can prevent recurrences over time, but the biggest immediate benefit comes from treating the first outbreak. Antibiotics aren’t needed since HSV is a viral infection.
