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. Although, the first cold sore you get will likely last longer. Most people don’t require treatment for their cold sores, but, in some cases, a doctor may prescribe an antiviral medication such as Valtrex. Valacyclovir belongs to the class of medications known as antivirals. It is used to treat a viral infection affecting the skin known as shingles (herpes zoster). It is also used to treat cold sores, and to treat and prevent recurrences of genital herpes. It works by interfering with the way the virus reproduces. Valacyclovir works by stopping the virus from multiplying and spreading to nearby healthy cells. It does not cure shingles, cold sores, or genital herpes, but it does help the sores to heal more quickly, and it relieves pain and discomfort. When used to prevent recurrences of herpes, it also reduces the risk of transmission (spreading) of the infection to others.
