Zovirax is an antiviral drug, which treats the infection caused by herpes - herpes simplex, herpes on lips, cold sores, shingles, genital herpes, chicken pox and others. It helps to fights herpes. It makes symptoms of the infection less painful and irritating.
Study of immunocompetent patients with localized cutaneous herpes zoster infection, Zovirax (800 mg 5 times daily for 10 days) shortened the times to lesion scabbing, healing, and complete cessation of pain, and reduced the duration of viral shedding and the duration of new lesion formation.
In a similar study, Zovirax (800 mg 5 times daily for 7 days) shortened the times to complete lesion scabbing, healing, and cessation of pain; reduced the duration of new lesion formation; and reduced the prevalence of localized zoster-associated neurologic symptoms (paresthesia, dysesthesia, or hyperesthesia).
Treatment was begun within 72 hours of rash onset and was most effective if started within the first 48 hours. Adults greater than 50 years of age showed greater benefit.
