Some are used topically (on the skin) and others are used orally (by mouth), but the goal is to treat cold sores as early as possible. That's because starting a medication when prodromal symptoms such as burning, tingling, or redness begin will give a person with a cold sore the best chance of either preventing an actual blister from forming or shortening a blister's course once it does appear. While the FDA has approved the use of certain drugs for cold sores, some antiviral drugs aren't specifically FDA-approved for cold sores but have been shown in clinical studies to be effective treatments. Given this, receiving a prescription for an off-label use of one of these drugs may help eliminate or prevent cold sores.
