What is Famvir?

Famvir is an antiviral drug. It slows the growth and spread of the herpes virus so that the body can fight off the infection. Famvir will not cure herpes, but it can lessen the symptoms of the infections.

Famvir is used to treat infections caused by herpes viruses. Illnesses caused by herpes viruses include genital herpes, cold sores, shingles, and chicken pox.

How should I take Famvir?

Take this medication exactly as it was prescribed for you. Do not take the medication in larger amounts, or take it for longer than recommended by your doctor.

Treatment with Famvir should be started as soon as possible after the first appearance of symptoms (such as tingling, burning, blisters).

Take each dose with a full glass of water. Drink plenty of water while you are taking this medication to keep your kidneys working properly.

Famvir can be taken with or without food. Taking Famvir with food may decrease stomach upset.

Take this medication for the entire length of time prescribed by your doctor. Your symptoms may get better before the infection is completely treated. Famvir will not treat a viral infection such as the common cold or flu.

Lesions caused by herpes viruses should be kept as clean and dry as possible. Wearing loose clothing may help to prevent irritation of the lesions.
