About Valaciclovir

Valaciclovir is an antiviral medication used to treat infection caused by the herpes virus. It is the better value generic form of Valtrex, a well-known herpes treatment in the UK. It is often used in the treatment of outbreaks of genital herpes but can also be used for suppression or preventative therapy if outbreaks occur often or are particularly severe.

How does Valaciclovir work?

Valaciclovir works by stopping the herpes simplex virus from multiplying. This, in turn, allows the body's immune system to battle the infection. Although this can ease symptoms and lessen the duration of the outbreak, genital herpes cannot currently be fully eliminated from the body with any treatment.

Valaciclovir Dosage

To treat genital herpes in adults, Valaciclovir should be taken twice daily. 

If Valaciclovir is being used to suppress an outbreak, the dosage is one tablet twice daily. Suppression treatment is used in people who have frequently recurring outbreaks of herpes. This is generally defined as more than 6 outbreaks per year.

The prophylactic treatment can help reduce, or completely stop recurring outbreaks. In addition, future outbreaks generally don't last as long and are less aggressive. 

It is important to drink plenty of water when taking a course of these antivirals to minimise potential side effects.

Comparing Valaciclovir, Aciclovir and Famciclovir

All of the main treatments for genital herpes are anti-virals which work in the same way. The main point of difference is that while Valaciclovir and Famciclovir need to be taken twice daily, Aciclovir requires three times daily dosage. This makes compliance with the herpes eradication regimen a little easier with Valaciclovir. 

Valaciclovir is, however, a more expensive option than aciclovir, but much cheaper than Valtrex in the UK.

Valaciclovir Side Effects

Like all medicines, Valaciclovir has the potential to cause some side effects. Not everyone will experience side effects but if you do, speak to your doctor.
Common side effects of Valaciclovir tablets are:

  • Stomach pain
  • Diarrhoea
  • Tiredness
  • Headache
  • Nausea
  • Sensitivity to light
  • Rash
  • Vomiting
  • Itching
  • Hives

If you experience any severe side effects or symptoms of an allergic reaction (breathing difficulties, itching, hives, rash) you should seek immediate medical attention. If you experience any prolonged side effects you should speak to the prescribing doctor.

  • What is genital herpes?

    Genital herpes is a sexually transmitted infection caused by the herpes simplex virus.

  • What are the symptoms of genital herpes?

    The main symptoms of genital herpes are painful blisters and sores which occur around your genitals, buttocks and thighs. 

  • How can I treat genital herpes?

    Antivirals are required to treat genital herpes. These include Aciclovir, Famciclovir and Valaciclovir.

  • Can you cure genital herpes?

    Once the virus is contracted, it will remain in your body for life. You will not always, or may never display symptoms however. 

  • Can you get genital herpes from a cold sore?

    Unfortunately yes. If someone who has a cold sore performs oral sex on you, it's possible you will contract the herpes virus which can lead to genital herpes.

  • How do I test for genital herpes?

    You should contact your local sexual health clinic or GP to get a test for genital herpes.

    You can also find home test kits online.

  • What happens if I have genital herpes while pregnant?

    You should seek help from your GP. You should not take any antiviral medication without consultation, as these may cause complications for both you and your baby.

  • Are there alternative treatments for genital herpes?

    You can use a local anaesthetic gel to help deal with painful outbreaks of genital herpes.

    This would usually be used in conjunction with an antiviral medication.
