Question: how long does it take to get rid of a cold sore with zovirax cream?
Answer: You can still begin to use it once a blister has appeared. Use it for no more than 4 days. If your symptoms do not improve after 4 days of treatment with ZOVIRAX Cold Sore Cream, you should tell your doctor. If you forget to use the cream at any time, use it as soon as you remember.
