Valtrex

Valtrex is an oral medication that doctors prescribe to control herpes outbreaks in an effort to minimize the effect of the herpes outbreak and in an attempt to prevent further outbreaks (suppressive therapy) in patients with the herpes simplex virus.

The herpes simplex virus commonly occurs in the genitals of the infected person, but herpes can develop on the face in the form of cold sores.

Valtrex can also treat chickenpox and cold sores in children. In adults Valtrex treats cold sores and shingles, but Valtrex does not cure these conditions in adults or children.
