Valtrex (Valacyclovir) is used to treat herpes zoster (shingles) and genital herpes. It does not cure herpes infections but decreases pain and itching, helps sores to heal, and prevents new ones from forming. This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information. Valacyclovir (Generic) is available for purchase.
Valacyclovir comes as a tablet to take by mouth. It is usually taken every 8 hours (three times a day) for 7 days to treat shingles. To treat genital herpes it is usually taken twice a day for 5 days. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take valacyclovir exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. Use this medication as soon as possible after symptoms appear. Continue to take valacyclovir even if you feel well. Do not stop taking valacyclovir without talking to your doctor.
