Valacyclovir commonly sold as Valtrex is one of the most widely used and effective drugs on the market for treating and controlling cold sores, shingles and genital herpes. Valacyclovir is also commonly prescribed for chickenpox, which is caused by the varicella zoster virus VZV.

The amount of time required for valacyclovir to start working can vary based on a number of factors, ranging from the type of infection you have to your valacyclovir dosage and the total amount of time that passes after you notice symptoms but before you start treatment.

The standard dosage of valacyclovir for first-time herpes outbreaks is 1, mg two times per day over a period of 10 days. It can take up to 10 days or, in some cases, even longer for herpes blisters to heal even with valacyclovir treatment. This makes it important to start treatment as soon as you notice herpes symptoms. In some cases, your doctor might prescribe valacyclovir for a longer period than 10 days or at a different dosage. Herpes can remain dormant in the body for weeks, months or years in between outbreaks.

Drink extra fluids so you will pass more urine while you are using this medicine. This will keep your kidneys working well and help prevent kidney problems. To help clear up your infection, keep taking valacyclovir for the full time of treatment, even if your symptoms begin to clear up after a few days.

Follow your doctor's orders or the directions on the label. The following information includes only the average doses of this medicine.

If your dose is different, do not change it unless your doctor tells you to do so. The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.
