Valacyclovir: Drug Description
Cold sores and genital herpes are common infections caused by herpes virus. Both cold sores and genital herpes are associated with painful lesions that cause much discomfort. Once a person has been infected with herpes virus, it never goes away. Virus remains dormant in the body and may become active again.
You can wait until herpes symptoms go away on their own, or you can use Valacyclovir to reduce the severity and duration of herpes outbreaks. Generic Valacyclovir is used to treat symptoms of infections with herpes virus, such cold sores, genital herpes, shingles, and chickenpox.
Although Valacyclovir will not cure cold sores or genital herpes, it reduces the severity and duration of its outbreaks and helps relieve the pain and discomfort. It also helps the sores or lesions to heal more quickly.
If you have frequent herpes outbreaks, your doctor may recommend that you take Valacyclovir tablets regularly to suppress the virus and prevent its outbreaks. When taken regularly, Valacyclovir also reduces the risk of spreading herpes virus to your sexual partner.
