Definition
Zovirax is the brand name for acyclovir, an antiviral medication used to treat herpes infections. It works by stopping the virus from replicating, reducing the severity and duration of outbreaks. Think of it as a targeted attack that disrupts the virus's ability to spread. It's commonly used for cold sores, genital herpes, shingles, and chickenpox. While it doesn't cure these infections, it helps manage them.
