Can you put too much Abreva on a cold sore?Small amounts of Abreva® Cream that get just inside the lip or mouth junction by the cold sore should not be a problem. However, if you accidentally place a large amount of cream into your mouth, then remove the cream, rinse out your mouth with water and contact your health professional.
Can Abreva heal a cold sore in 2 days?Abreva® can heal a cold sore in as few as 2½ days when used at the first sign. Nothing heals a cold sore faster. Dealing with a cold sore isn't fun but knowing what causes cold sores, how they spread and the best way to treat them will help you take charge and defend yourself against future outbreaks.
Does Abreva help cold sores that have already formed?Will Abreva® Cream help if I start to apply it after the blister has developed?
