Cold sores are painful and oozing, and they always seem to appear before that wedding or class reunion. Cold sores are typically caused by type 1 virus (HSV-1). Also called fever blisters, the small, fluid-filled lesions typically form near or on your lips and can cause symptoms such as tingling, itching, or burning. But in some cases, HSV-1 can cause sores on the genitals and type 2 virus (HSV-2) can cause sores on the mouth. But, because they’re caused by a virus, they can be treated with antiviral medications. Valtrex, which contains the active ingredient valacyclovir, can help your cold sores clear up faster. It can also reduce the number of cold sores you get. Read on to learn how Valtrex works and how to use it to treat your cold sores. Cold sores typically start to heal on their own within about four to six days.

To Treat Or Abort An Outbreak When There Are Early Symptoms (Prodrome): For both genital and oral herpes, people can take medication when their specific prodrome tells them an outbreak is about to occur. The medication will stop an outbreak cold (often) and when it does not, it can shorten the outbreak and make it milder than it might have been otherwise. To Prevent Outbreaks When There Are No Symptoms But Outbreaks Are More Likely: Patients also learn the life circumstances or behaviors that lead to more outbreaks. For some, a lack of sleep, increased alcohol, another illness, stress, too much sunlight, irritation, or anything that can affect one’s immunity can spur an outbreak. That means that some patients can know not just when they feel an outbreak coming on but can know when they are more likely to have an outbreak due to their circumstances. They might be under stress, having more sex therefore causing more physical irritation, drinking a bit more than they should, or missing sleep over an extended period.
