acyclovir

Acyclovir is an antiviral medication used to treat infections caused by the herpes virus, including cold sores, genital herpes, and shingles. It works by blocking the virus's ability to replicate, helping to reduce the severity and duration of symptoms. Acyclovir does not cure the infection but can help manage outbreaks and decrease spreading to others. It’s available in various forms, such as tablets, creams, and injections, and should be used as prescribed by a healthcare provider for the best results.
