Fever Blister Medication

If you experience pain and discomfort from a fever blister, medication can be taken to improve symptoms and to speed up the healing process. These medicines, which are available over-the-counter and by prescription, come in the form of tablets, ointments, and creams. Lysine is a supplement that can also be used for treating and preventing fever blisters.

All of these medicines work best if used at the first sign of a fever blister (symptoms often include tingling, itching, burning, or redness).
