Valtrex 500 mg

Valtrex is an antiviral drug which used to treat certain herpes infections, including herpes zoster (the painful rash known as shingles), genital herpes, and herpes cold sores on the face and lips. Valtrex stops viral replication and combats the herpes virus attacking it and slowing it down from replicating itself in the system allowing the body to assist in the natural defense of the spread of this virus ultimately limiting both the duration and frequency of outbreaks. Valtrex will not cure herpes, it just lessen the symptoms of the infection.
