What is Valacyclovir?

Valcyclovir is an antiviral medication recommended for treating herpes infections, such as genital herpes, cold sores, and shingles. It is also used to treat outbreaks of herpes simplex or herpes zoster. It stops the growth and spread of herpes along with the pus-filled blisters as a symptom of Valcyclovir.

What are the uses of Valacyclovir?

Valcyclovir is an antiviral medication used to treat herpes. Some of the most prominent uses of valacyclovir are:

  • Preventing recurrent outbreaks of herpes simplex virus (HSV) infections.

How does it work?

Valacyclovir works by inhibiting the replication of herpes viruses, including herpes simplex virus (HSV) and varicella-zoster virus (VZV). Once ingested by contact, it is converted into acyclovir in the body. Acyclovir then interferes with viral DNA production, reducing the virus’s ability to multiply and spread. This helps decrease symptoms, shorten outbreak duration, and reduce recurrences’s frequency.
