For over 25 years now, prescription ZOVIRAX® (acyclovir) Ointment 5% has been the only ointment indicated to help people manage their initial genital herpes outbreaks. While ZOVIRAX Ointment does not prevent the spreading of genital herpes, it does attack the herpes simplex virus (HSV-2) and stop it from copying itself at the site of the lesion.
Acyclovir: One Of The First Antiviral Medicines Ever Discovered
This prescription-strength ointment contains acyclovir, which was among one of the first antivirals approved by the FDA. In fact, prescription ZOVIRAX Ointment contains 5% acyclovir. This active ingredient was a medical breakthrough in the 1970s and is still used today. When it comes to genital herpes, ZOVIRAX Ointment is the only prescription ointment that helps manage the duration of the itching and pain associated with an initial outbreak.
