Aciclovir is an antiviral medicine used to treat infections caused by the herpes virus. It is commonly prescribed to treat genital herpes, cold sores, chickenpox and shingles. Aciclovir does not cure viral infections. It helps sores to heal, reduces itching and eases pain. Aciclovir can prevent infections in people who have a weak immune system due to medical conditions or the medicines they take.
The two most common infections caused by the herpes virus are cold sores and genital herpes. While symptoms usually clear up, the virus stays in your skin for the rest of your life. You may experience random outbreaks of cold sores or genital herpes. People who have more than 6 outbreaks in a year can take aciclovir for 6 to 12 months as a preventative, or see a specialist for advice.
Aciclovir does not cure genital herpes or cold sores. Cold sores can take up to 10 days to heal, and aciclovir stops them from spreading or getting worse.
