Aciclovir

Aciclovir is a medication used to treat infections caused by herpes viruses, including cold sores, genital herpes, and shingles. It works by stopping the virus from multiplying, which helps reduce the severity and duration of symptoms. Aciclovir is usually taken as a pill, cream, or injection, depending on the infection. It doesn't cure the virus but can help manage outbreaks and make them less severe. It's most effective when started early in the course of an outbreak. As with all medicines, it should be used under your healthcare provider's guidance.
