Frequently Asked Questions for Valtrex

What It Is

Valtrex is an antiviral drug used to treat herpes simplex virus (HSV) infections, including genital herpes, cold sores, shingles, and chickenpox. The active ingredient, valaciclovir, converts into aciclovir in the body, where it works to prevent the virus from replicating, speeding up recovery and reducing symptoms.

How It Works

Valtrex works by converting into aciclovir once inside the body. Aciclovir blocks the viral DNA polymerase enzyme, which the herpes virus needs to replicate. By inhibiting this enzyme, Valtrex helps prevent the virus from multiplying, reducing symptoms, and allowing the immune system to control the infection more effectively.

How It Is Used

For genital herpes outbreaks: Take 500mg twice daily for 5 to 10 days.
