Valacyclovir (generic for Valtrex) is a medication approved by the FDA to treat different types of herpes infections including HSV-1 and HSV-2. It is also used to treat shingles (herpes zoster), which is caused by the Varicella Zoster Virus (VZV). There are four different ways that herpes medications can be used to treat genital herpes (HSV-1 and HSV-2): 1. 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. Shingles is a painful skin rash that usually appears on one side of your waist, but can also affect your chest, back, legs or face. Shingles is caused by the varicella-zoster virus, which is the same virus that causes chickenpox. You can only get shingles if you have had chickenpox. After you have had chickenpox, the virus remains in your body and lies dormant in your spinal nerves. Approximately 20% of people will subsequently experience shingles, but the extent and risk of complication differs for everyone. You develop shingles if the virus is reactivated, which is most likely to happen in people with lowered immunity. This can be as a result of illness, surgery, ageing, HIV infection or certain medicines, such as steroids. Rarely, shingles may occur in young children who were either born with chickenpox or had it soon or after birth. You cannot catch shingles from someone who has shingles or from someone who has chickenpox.
