Luckily, cold sores are easy to treat using readily available, affordable medication. The most common medication used to treat recurrent cold sore outbreaks is valacyclovir. Valtrex (valacyclovir hydrochloride) is FDA approved for the treatment of herpes simplex (cold sores and genital herpes) and varicella zoster virus (chickenpox and shingles). It is an antiviral agent in a class called DNA polymerase inhibitors. These two viruses are closely related and are quite prevalent in the U. with an estimated 45 million people, 12 years and above infected with herpes simplex virus alone. This is particularly important in view of the concurrent HIV/AIDS epidemic. The fact is that sores caused by the herpes simplex viruses facilitate HIV transmission, and HIV infection encourages drug resistance and more severe disease scenarios in herpes simplex infections. Herpes simplex viruses and varicella zoster viruses are DNA viruses that carry their own genetic material. When they infect a human cell, they hijack it producing viral genetic material and other proteins and enzymes that are reassembled into new infective viruses and released.
