For which condition is Zovirax indicated for treatment?

Zovirax, the brand name for acyclovir, is primarily indicated for the treatment of viral infections, specifically those caused by the herpes virus. This includes conditions such as genital herpes, which is a sexually transmitted infection characterized by painful blisters or sores in the genital area, as well as shingles (herpes zoster), which occurs due to the reactivation of the varicella-zoster virus in individuals who have previously had chickenpox.

In these cases, Zovirax works by interfering with the viral DNA replication, thereby reducing the severity and duration of the outbreaks and contributing to healing. The selection of Zovirax for these conditions is grounded in its effectiveness and the specific mechanisms it employs against herpes viruses, which distinguishes it from treatments for conditions like benign prostatic hyperplasia, painful musculoskeletal issues, or hypothyroidism, where antiviral medications would not be applicable.
