Take valacyclovir 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. Follow the directions on your prescription label.
Treatment with valacyclovir 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 valacyclovir to keep your kidneys working properly. Shake the oral suspension (liquid) well just before you measure a dose. To be sure you get the correct dose, measure the liquid with a marked measuring spoon or medicine cup, not with a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one.
Valacyclovir 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. Valacyclovir 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.
Store valacyclovir tablets at room temperature away from moisture and heat. Store the liquid in a refrigerator. Do not freeze. Throw away any unused valacyclovir liquid that is older than 28 days.
Valacyclovir may be given without regard to meals.
Valacyclovir oral suspension (25 mg/mL or 50 mg/mL) may be prepared extemporaneously from 500-mg Valacyclovir Caplets for use in pediatric patients for whom a solid dosage form is not appropriate.
