Zovirax is prescribed to treat initial genital herpes infections and to treat patients with recurrent (6 episodes per year) severe genital herpes. Zovirax reduces the pain and the number of lesions in the initial case, and decreases the frequency and severity in those with recurrent infections. In the treatment of shingles, Zovirax reduces pain, shortens the healing time, and limits the spread of virus and the formation of new lesions. Zovirax can be prescribed to treat chicken pox and acts to reduce healing time, limit the number of lesions, and reduce fever if prescribed within the first 24 hours after the onset of the disease.
Zovirax ointment is prescribed topically to treat initial genital herpes where it has been shown to decrease pain, reduce healing time, and limit the spread of the infection.
