How does valaciclovir work?

Like other antiviral medicines, valaciclovir works by stopping the virus (HSV) from multiplying, so your immune system can effectively deal with the cold sore infection. Antiviral medicines help to reduce the severity of your symptoms and also speeds up healing.

Inside your body, valaciclovir is converted to aciclovir which enters the body’s cells. Here, aciclovir works by blocking the enzyme HSV uses to multiply and stopping its spread, so your immune system can fight and overcome it.

You can treat genital herpes two ways. One treatment option is for when you experience an individual outbreak (acute therapy) and the other is treatment for when you need to avoid regular outbreaks (suppressive).
