About Valaciclovir
Valaciclovir or Valacyclovir is a prescription-only antiviral medicine, which is used to treat or suppress genital herpes simplex of the genitals. as well as cold sores, chickenpox and shingles.
Valaciclovir will not cure genital herpes, but it will suppress the virus, helping to control the painful symptoms or prevent outbreaks.
There are two types of herpes simplex virus: HSV-1 and HSV-2, both of which can cause symptoms on the genitals, lips and fingers. Valaciclovir can be used to treat both HSV-1 and HSV-2.
Once you have caught herpes simplex, the virus may remain inactive for many years, during which time you will not have any symptoms. When the virus is active, it can cause pain, itching, stinging and blisters. Valaciclovir is an antiviral medicine, which stops the virus from replicating and can be used to treat the symptoms or prevent outbreaks.
For your treatment to work, take Valaciclovir as soon as you notice symptoms, and ideally within five days of the first herpes symptoms appearing. Always follow the doctor’s instructions on how to take your medication.

Which dosage do I need to take?
You should aim to begin antiviral treatment within the first five days of noticing herpes symptoms, but taking Valaciclovir within the first two days of an outbreak produces the best results. If you are being treated for your first outbreak of herpes, the doctor may prescribe a dose of one 500mg Valaciclovir tablet taken twice daily for five days, or up to ten days if new lesions appear during treatment or if healing is incomplete.
If you are having a repeat outbreak of herpes the doctor may prescribe the same dosage (500mg) per day, but for only three to five days. Always follow the doctor’s instructions on how to take your medication.
Can I have intercourse during treatment?
You should not have sex during an episode of herpes, as this puts your partner at risk of contracting genital herpes. Genital herpes can also be transmitted during oral and anal sex.
