Item name:

Generic name:

valacyclovir (oral)

Brand names:

Valtrex

Item info:

Valacyclovir is an antiviral drug. It slows the growth and spread of the herpes virus so that the body can fight off the infection. Valacyclovir lessens the symptoms of these infections and shortens the length of time you are sick. Valacyclovir is used in the treatment and suppression of genital herpes, shingles, and cold sores. Valacyclovir is not a cure for herpes virus infections.

Drug class:

Antiviral Interactions: Probenecid (Benemid) may increase the effects of valacyclovir and possibly lead to dangerous side effects. You may need a dosage adjustment or special monitoring during treatment if you are taking probenecid or cimetidine. Drugs other than those listed here may also interact with valacyclovir. Talk to your doctor and pharmacist before taking any prescription or over-the-counter medicines, including vitamins, minerals, and herbal products.

Side effects:

Stop taking valacyclovir and seek emergency medical attention if you experience an allergic reaction (difficulty breathing; closing of the throat; swelling of the lips, tongue, or face; or hives).

Other, less serious side effects may be more likely to occur. Continue to take valacyclovir and talk to your doctor if you experience:

•   nausea, vomiting, diarrhea, constipation, or abdominal pain; 
•  headache; 
•  dizziness; or 
•  tremors.

Side effects other than those listed here may also occur. Talk to your doctor about any side effect that seems unusual or that is especially bothersome.

Prescription needed / OTC:

RX Only

Dosage:

Take valacyclovir exactly as directed by your doctor. If you do not understand these directions, ask your pharmacist, nurse, or doctor to explain them to you.

Treatment with valacyclovir should be started as soon as possible after the first appearance of symptoms (e.g. for cold sores-tingling, burning, blisters).

Take each dose with a full glass of water. Valacyclovir can be taken with or without food. Taking valacyclovir with food may decrease stomach upset.

Take all of the valacyclovir that has been prescribed for you even if you begin to feel better. Your symptoms may start to improve before the infection is completely treated. It is important to take valacyclovir regularly to get the most benefit.

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.

Herpes infections are contagious and you can infect other people, even during treatment. Avoid letting infected areas come into contact with other people. Wash your hands frequently to prevent transmission.

Valacyclovir will not prevent the spread of genital herpes. Avoidance of sexual intercourse and use of latex condoms may prevent spreading the virus to others.

Contraindications:

Do not take valacyclovir without first talking to your doctor if you are allergic to acyclovir (Zovirax). Before taking this medication, tell your doctor if you have kidney disease or immune system problems. You may need a dosage adjustment or special monitoring during treatment with valacyclovir.

Valacyclovir is in the FDA pregnancy category B. This means that it is not expected to be harmful to an unborn baby. Do not take this medication without first talking to your doctor if you are pregnant or could become pregnant during treatment. It is not known whether valacyclovir passes into breast milk and how it may affect a nursing baby. Do not take this medication without first talking to your doctor if you are breast-feeding a baby.

Storage:

Store valacyclovir at room temperature away from moisture and heat.
