Cream for local treatment of herpes simplex and cold sores.


Active Ingredients

Aciclovir 5% w/w

An antiviral agent.


Zovirax is used for the treatment of cold sores (herpes simplex).


The recommended dosage: apply at the first signs of a cold sore (such as tingling and itching).  Apply liberally to the affected area 5 times a day. Continue treatment for 5 days. If your cold sore has not healed after this time, you can use the cream for up to 10 days in total. Treat your cold sore for 5 full days to ensure rapid healing.

Never give your Zovirax to others, even if their symptoms are the same as yours.

Always wash your hands before and after applying Zovirax.

Do not touch your eyes as long as you have not washed your hands after application.

Avoid touching a cold sore to prevent transferring the infection or making it worse.

Avoid kissing - especially children - when you have a cold sore.

Avoid touching your eyes. Herpes simplex virus (HSV) infection of the eye can lead to ulcers on the window of the eye (cornea).

Do not share your eating and drinking utensils.


Do not swallow the cream. For external use only.

Do not use Zovirax if you have ever had an allergic reaction to aciclovir, valaciclovir, propylene glycol or any of the other ingredients.

Do not use Zovirax inside your mouth to treat mouth ulcers, in the eyes or genital area.

Talk to the physician or pharmacist before using Zovirax if you are pregnant, trying to become pregnant or breastfeeding.
