Valaciclvor is an antiviral treatment for the herpes virus. It is used to treat genital herpes, cold sores and shingles. It doesn't cure the virus but it works to reduce outbreaks of herpes, easing the pain or discomfort and helping the sores to heal faster.
Valaciclovir will start to work as soon as it is in your system but it will take a few days to make a visible difference. The first time you are being treated for herpes, the sores can take up to ten days to disappear. For consecutive treatments, Valaciclovir will usually work in 3-5 days.
If you have herpes, you will be contagious during an outbreak of sores. Even if you are taking Valaciclovir, you should not have sex until your blisters have healed. If you have cold sores around your mouth then you should avoid kissing until they have disappeared again.
Valaciclovir can also be used to prevent outbreaks of herpes if you experience frequent outbreaks of sores. Always take it as your doctor has prescribed it.
Valaciclovir can also be prescribed to treat cold sores, shingles and chickenpox in children.
