Zovirax

Zovirax is best known for its brand of over the counter and general sale cold-sore cream. However, the popular medicine also comes in tablet form and as an oral solution. Whilst this might sound strange for the treatment of the common cold-sore, these forms of zovirax exist to treat the following conditions:

  • Genital herpes
  • Shingles
  • Chicken pox

Zovirax can treat a range of conditions that are caused by either the herpes simplex or the herpes zoster virus.


The form, dose, and treatment period of your medicine will depend on which condition its treating and the severity of it, meaning that you could be taking it for anywhere between 5 days and 12 months. A GP will be able to advise you on the most appropriate dosage and treatment period according to your condition.


Zovirax is generally well tolerated and can be taken by most people, but always read the patient information leaflet that’s included in your medication to make sure that it won’t harm you.

What is zovirax?

You might know Zorirax as the cold-sore killing cream that you can buy over the counter and in some supermarkets, but Zovirax can also help to treat conditions such as genital herpes, shingles and chickenpox.

Zovirax contains the active ingredient aciclovir, which can treat several conditions associated with the herpes simplex and herpes zoster viruses.

It can come as a tablet, oral solution, or topical cream depending on which condition you’re treating with the medicine.

What are the side effects of Zovirax?

Depending on which form of zovirax you take, you might experience some of the following symptoms as a result of the medication:

  • headache
  • dizziness
  • nausea
  • diarrhoea
  • abdominal pain
  • rash
  • photosensitivity
  • itching
  • fatigue
  • fever
  • hives
  • hair loss
  • anaemia
  • weakness
  • shaking
  • hallucinations
  • confusion
  • stiff neck
  • fits

Some of these side effects are incredibly rare, but if you do experience any of the more serious ones, please contact your GP for advice. For the milder side effects, there may be other medicines or remedies you can use to cope with them if the benefits of zovirax outweigh the risks. The list above isn’t extensive, please see the patient information leaflet included with the medication for the full list.

Can I take zovirax with other medicines?

Most medicines are safe to use with zovirax, but there are some exceptions. You shouldn’t use any other medicines containing aciclovir at the same time as zovirax, as this might increase the risk of overdose. Symptoms of an overdose include:

  • nausea
  • vomiting
  • headache
  • confusion
  • agitation
  • extreme fatigue
  • loss of consciousness
  • seizures
  • kidney failure
  • producing no urine

to reduce the risk of overdose, only take the amount of medicine stated for your daily dose.

Other medicines that might cause adverse effects whilst taking zovirax include:

  • NSAIDs (anti-inflammatory medicines such as naproxren and ibuprofen)
  • Trimethoprim
  • Tacrolimus
  • Ciclosporin
  • Cephalexin
  • Probenecid
  • Cimetidine
  • Mycophenolate mofetil

If you need to take painkillers alongside zovirax, there are no known interactions with paracetamol. Ask a pharmacist of GP about using other pain relief medications whilst taking zovirax.

Who can take Zovirax?

Most people are able to take zovirax without adverse effects, but there are some people that need to ask advice from a doctor before using the treatment. These include people who:

  • Are pregnant
  • Are breastfeeding
  • Have kidney damage or kidney disease
  • Have a condition that weakens the immune system (such as HIV, AIDS and others)

If you fall into any of the above categories, you might still be able to use zovirax for your condition under the careful eye of a healthcare professional, butt the risks are increased slightly. For example, some medications that people with these conditions use can interact with zovirax.

How long do I need to take zovirax for?

The length of your treatment will depend on the condition that you have and its severity. The medication can be taken for as little as 5 days up to 12 months depending on the circumstances. General guidelines are as follows:

  • Shingles: When Zovirax is used for the treatment of shingles, the recommended dose is 800mg taken 5 times a day for 7-10 days
  • Genital herpes: The recommended dose of zovirax for this condition is 200mg taken 5 times a day for 10 days
  • Prevention of genital herpes: If you’re using the medication to prevent the reoccurrence of genital herpes, you should take 400mg once every 12 hours for a year
  • Chicken pox in adults: Whilst this isn’t as common as shingles, the treatment guidelines for adult chicken pox is 800mg to be taken 4 times a day for 5 days

As you can see, the dosages and treatment periods vary greatly depending on what the medication is treating. A doctor may decide to extend treatment if results are showing but the symptoms haven’t disappeared within the time specified.

How do you take zovirax?

This depends on what form of the medicine you’ve been prescribed.

If you’re taking Zovirax in tablet form, you have two options. You can either dissolve the tablet in a little bit of water and drink it, or you can swallow it whole with a little water. It doesn’t matter whether you take it with or without food.

If you’re using the oral solution, you still need to take the right amount for however may times is specified, but you don’t need to take it with water.

For the topical treatment of cold sores, you should use zovirax cream and apply it topically to the affected area. Don’t use the cream internally.
