Your healthcare provider may prescribe a drug called Xerese™ (acyclovir and hydrocortisone) if you have been diagnosed with a cold sore. This medication comes in the form of a cream that is applied to the affected area five times a day for five days. Using this product can not only shorten the amount of time it takes your cold sore to heal, but can also make it less likely for your cold sore to get worse.
