Valtrex is an oral tablet made up of a purine nucleoside antiviral drug called valacyclovir. We carry the brand choice and generic alternative of this medication in 500mgand 1000mg!

Valtrex is an antiviral medication which means it is used to treat infections caused by certain viral viruses. Children use this medication to treat chickenpox (varicella), an infection that causes small, itchy blisters, which eventually scab over. Adults typically don’t get the chickenpox, however, they may be more prone to other viral infections such as shingles (also known as herpes zoster), an infection similar to the chickenpox that is characterized by painful body rashes, caused by the same virus as chickenpox. Additionally, Valtrex can be used by both children and adults to help treat cold sores around the mouth (caused by herpes simplex), a condition where singular or multiple blister/pimple-like rashes appear on the lips.

Valtrex (valacyclovir) is effective at treating viral infections due to its capability to stop the growth of the virus causing the infection. Valtrex should not be mistaken as a cure for these infections, Valtrex may be used to help the infection heal faster, keeps new infections from occurring, and decreases pain/itching.

Only take this medication the way that your doctor has directed you too. Taking the incorrect dose can lead to unwanted side effects, ineffectiveness, or adverse interactions; avoid taking more or less of a dose than recommended or taking it for a shorter or longer period of time. For the best effect, you should begin taking Valtrex as soon as you recognize the symptoms of your condition (such as burning, tingling, or blisters); taking the medication in the following days of the first few symptoms may reduce effectiveness.

You may take this mediation with or without food, but ensure you are drinking plenty of fluids, preferably water, during the time of treatment. While taking Valtrex, ensure you are not wearing tight clothing as lesions caused by herpes should be kept as clean and dry as possible.

Store this medication at room temperature in a low risk area of moisture and heat.
