More information about Valtrex

What is Valtrex?

Valtrex is an antiviral medication used to treat herpes simplex viruses, including genital herpes (herpes simplex strain 2, HSV-2) and cold sores (herpes simplex strain 1, HSV-1). It also treats varicella zoster virus (VZV, herpes zoster), which causes chickenpox and shingles. It is also used to prevent infections in those who are immunocompromised, including preventing CMV (cytomegalovirus) in those who’ve had organ transplants.

It is an oral prescription in the form of capsules that can offer relief from unpleasant blisters within 24 hours as well as significantly reduce the duration of your outbreak. Treatment is most effective when used at the first sign of infection.

How does Valtrex work?

Valtrex contains the active ingredient valaciclovir (valacyclovir) hydrochloride which belongs to a group of drugs known as 'prodrugs'. This means that it changes and adapts when it's inside the body to become more effective. When valaciclovir is absorbed into the system, it evolves into is parent drug aciclovir (acyclovir) which allows more of the active ingredient to be absorbed into the system and ensure effective treatment.

Valtrex works specifically by targeting the virus cells responsible for the growth and duplication of the viral DNA. This prevents the virus from duplicating itself and spreading from one healthy cell to another. It allows your body's natural defences to fight back, and drive the virus back to an inactive state.

How do I take Valtrex?

Each tablet is 500mg, but the dosage will depend on the form of herpes and whether you’re treating an initial bout, a recurrent bout or preventing infection. Your dose may also be adjusted if your symptoms persist after you complete your course or you have a weak immune system, kidney problems or are over the age of 65.

Valtrex should always be taken for the full course, regardless of whether the symptoms subside during the course.

The recommended dosages are the following:

It is also advised to drink plenty of fluids whilst taking this medication to avoid dehydration. You should swallow the tablets whole, do not crush, break or split tablets.

If you miss a dose, do not take a double dose. If it is nearly time to take your next tablet, just take your next scheduled dose as normal until the treatment finishes. If you remember long before your next dosage, take the tablet as soon as possible.

What are the side effects of Valtrex?

As with all prescription medication, there is a small risk of side effects. However, the most common side effects are usually mild and go away on their own within a few days.

Common side effects include:

If you experience any of the following more severe symptoms, you may be experiencing an allergic reaction.

Symptoms of an allergic reaction may include:

More severe side effects of Valtrex are rare, but symptoms should not be ignored. If you experience any severe side effects, you should stop taking Valtrex and seek immediate medical attention.

For a full list of side effects, please refer to the patient information leaflet which is available to download on this page and will be sent in the box with your medication.

What precautions should I take?

If you have previously had an allergic reaction to the active ingredient valaciclovir or the similar antiviral aciclovir, then you should not take this medication. Equally, if you are pregnant or breastfeeding, it is recommended that you speak to your doctor for an alternative.

Some groups of people should take particular caution before taking this medication and should speak to their doctor beforehand as you may be more at risk of side effects. This includes those who:

If you are not sure if any of the above apply to you, then you should consult with a healthcare professional before taking this medication.

In addition, once contracted, the herpes virus does not leave your body and can be transferred to partners at any time. Refraining from sex during outbreaks and making sure you are containing the virus is essential.

Does Valtrex react with any other medicines?

You should always inform whoever is prescribing you if you take any other medicines, this includes prescription, over-the-counter and herbal medicines. This is because your treatment may be affected.

The following medicines can affect kidney function when taken with Valtrex:

If you are not sure what medication you take, you should speak with your doctor before taking Valtrex.
