Acyclovir is an antiviral drug. This slows the growth and spread of the herpes virus in the body. It does not cure herpes, but it can reduce the symptoms of infection.
Acyclovir is used to treat infections caused by herpes viruses, such as genital herpes, herpes, shingles and chicken pox.
Acyclovir may also be used for purposes not listed in this medication guide.
Take Acyclovir for the entire length of time prescribed by your doctor. Your symptoms can get better before completely treating the infection.
Treatment with acyclovir should be started as soon as possible after the first appearance of symptoms (such as tingling, burning, blisters).
Herpes are contagious, and you can infect other people even while you are treated with acyclovir. Do not let contaminated areas come in contact with other people. Avoid touching the infected area, and then touching the eyes. Wash your hands often to prevent transmission of infection to others.
