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 be used as an alternative to fever blister medication for treating and preventing fever blisters.

An Introduction to Fever Blister Medication

A variety of fever blister medicines are available, including prescription medications, non-prescription medications, and supplements.
 

Prescription Fever Blister Medications

Topical prescription fever blister medicines (creams or ointments that are applied directly to the fever blister) include:
 
Oral prescription fever blister medications (tablets that are taken by mouth) include:
 
All of these medicines work best if used at the first sign of a fever blister (symptoms often include tingling, itching, burning, or redness).
 
It is important to understand that treatment with these fever blister medications does not prevent future outbreaks. They are also not approved for use in children (except Zovirax cream and Denavir cream, which can be used in children 12 years of age and older).
