Zovirax Cream 5% treats cold sores caused by the herpes simplex virus.
When you see skin blisters or recognise the tingling sensation that means a blister will soon appear, spread a thin layer of cream onto the cold sore to reduce pain and speed healing.
You can re-apply Zovirax cream about every 4 hours during your day (5 times per day), using a cotton bud.
This cream contains 50 milligrams of Aciclovir per gram. You must be aged over 18 to purchase this product.
