Valtrex
Valtrex
Valtrex (/'væltrɛks/), also known by its generic name Valacyclovir (/'væləˈsaɪkləvɪr/), is an antiviral drug used in the management and treatment of infections caused by the herpes simplex virus and varicella zoster virus.
Etymology
The name "Valtrex" is a brand name derived from its generic name, Valacyclovir. The "Val-" prefix is derived from "valine", an amino acid, and "-acyclovir" is derived from "acyclovir", the base drug, which is an antiviral medication.
Usage
Valtrex is primarily used to treat outbreaks of genital herpes, cold sores, and shingles. It can also be used to help prevent these infections in individuals with a weakened immune system.
Mechanism of Action
Valtrex works by slowing the growth and spread of the herpes virus in the body. It does this by inhibiting the viral DNA polymerase, an enzyme the virus needs to replicate.
Side Effects
Common side effects of Valtrex include headache, nausea, and abdominal pain. More serious side effects can include kidney problems and mental/mood changes.
