Cold sores are a common infection caused by the herpes simplex virus (HSV). Although there is no cure for a cold sore, there are medications that can help.
For example, XereseTM (acyclovir and hydrocortisone) is a prescription medicine licensed to treat cold sores in adults and children 12 years of age and older. It contains a combination of acyclovir and hydrocortisone, and comes in the form of a cream. Xerese is used to:
Shorten the time it takes for a cold sore to heal
Reduce the risk of a sore becoming worse.
Although most people are able to use this product without any problems, side effects are possible, including redness and dry, flaky skin.
