Valacyclovir (Valtrex): How to use, Side Effects, Dosage

What is Valacyclovir (valtrex)?

Valacyclovir belongs to the class of medications known as antivirals. Val acyclovir is used to treat infections caused by certain types of viruses. In children, it is used to treat cold sores around the mouth (caused by herpes simplex) and chickenpox (caused by varicella zoster). In adults, it is used to treat shingles (caused by herpes zoster) and cold sores around the mouth. This gives the body's immune system a better chance to fight off the infection and reduce the number of outbreaks

Valacyclovir is also used to treat outbreaks of genital herpes. In people with frequent outbreaks, this medication is used to reduce the number of future episodes. When used to prevent recurrences of herpes, it also reduces the risk of transmission (spreading) of the infection to others.

Valacyclovir is an antiviral drug. It stops the growth of certain viruses. However, it is not a cure for these infections. The viruses that cause these infections continue to live in the body even between outbreaks.
