Antiviral medications can help them heal faster if taken early. Talk to your doctor if your cold sores do not go away after two weeks. Helpful? 1 person found this helpful.
Treating cold sores. Unfortunately, there is no cure for cold sores. But the good news is that they often clear up without treatment. You can shorten the healing time by using an effective treatment like AbrevaÂ® Cream. It penetrates deep and starts to work immediately* to block the virus and protect healthy skin cells. You could heal your cold sore in as little as 2Â½ days*** when using AbrevaÂ® Cream at the first sign of an outbreak.
