Acyclovir (Zovirax) is an antiviral drug. It is used to treat infections caused by some types of herpes virus. However, it is not a cure for these infections. The virus continues to live in the body due to these infections. Acyclovir only reduces the length and severity of these outbreaks. Acyclovir is used to treat mouth ulcers around the mouth, shingles, chickenpox and genital herpes. People, who often suffer from it, take medicines to reduce future events.

It helps in healing wounds faster, prevents the formation of new wounds and reduces pain or itching. This medicine can also help reduce the time for which the pain persists after the ulcer heals. In people with a weakened immune system, Acyclovir may reduce the risk of the virus spreading to other parts of the body and causing serious infection. Treatment with Acyclovir should be started as soon as the first symptoms present, such as tingling, burning, blisters present themselves. Acyclovir does not harm a newborn baby. But a doctor should be consulted before taking this medicine. Especially if pregnant or planning to become pregnant. Some side effects include nausea, diarrhea, kidney problems, and low platelet count. Greater care is recommended for people with impaired kidney or liver function.
