What is Valtrex?
Valtrex is an antiviral drug which contains valaciclovir. It slows the growth and spread of the herpes virus so that the body can fight off the infection. It is a prescription medication licensed to treat several conditions related to infections with the herpes virus, including:
- Cold sores
- Shingles
- Genital herpes
- Chickenpox.
- Patients with genital herpes should refrain from having sex until the condition has fully cleared.
How should I take Valtrex?
Take Valtrex 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 Valtrex should be started as soon as possible after the first appearance of symptoms (such as tingling, burning, blisters). This medication might not be as effective if you first start taking it 1 or 2 days after the start of your symptoms.
Take each dose with a full glass of water. Drink plenty of water while you are taking Valtrex to keep your kidneys working properly.
Valtrex can be taken with or without food.
Take this medication for the entire length of time prescribed by your doctor. Your symptoms may get better before the infection is completely treated. Valtrex will not treat a viral infection such as the common cold or flu.
