Zovirax Cream 2g

Zovirax is used for the treatment of cold sores. The active ingredient is aciclovir, an antiviral agent. Apply at the first signs of a cold sore (such as tingling  and itching). It can also be used to speed up healing if one has already appeared.

Directions for use:

Suitable for all ages: 

  • 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 4 days. If your cold sore hasn’t healed after this time, you can use the cream for up to 10 days in total. 
  • Treat your cold sore for 4 full days to ensure rapid healing. 
  • If you forget a dose, apply when you remember and continue as before. 
  • If your cold sore hasn’t healed fully after 10 days, or if it gets worse at any time, contact your doctor.
  • Never give your Zovirax to others, even if their symptoms are the same as yours. 
  • The amount of cream inside this pack is enough for one cold sore attack. For any future attacks, start treatment at the first signs of a cold sore developing (such as tingling or itching). It can also be started during the blister stage.
  • Do not use more than the recommended dose.


Do not use Zovirax:

  • If you have ever had an allergic reaction to aciclovir, valaciclovir, propylene glycol or any of the other ingredients (listed below). 
  • Inside your mouth (e.g. for mouth ulcers) or nose. 
  • For any skin infection other than a cold sore. 
  • In the eyes or genital area.

Take special care with Zovirax

  • Always wash your hands before and after applying Zovirax.
  • Do not touch your eyes until you have washed your hands after application.
  • If you accidentally get cream in your eye, wash out thoroughly with warm water. Consult your doctor if you are concerned.
  • Do not swallow the cream. If you accidentally swallow any cream, it is unlikely to cause any ill effects but consult your doctor if you are concerned.
  • Avoid touching a cold sore to prevent transferring the infection or making it worse.
  • If you have been told by your doctor that you have a weakened immune system, contact your doctor before treating any type of infection.
  • If you are in any doubt if you have a cold sore, contact your doctor. 
  • If your cold sore gets very severe, contact your doctor. 
  • Tell your doctor or pharmacist before use if you are taking any regular medication on prescription or over the counter products.
