You may want to read it again. This leaflet provides information about Zovirax. The statements that are made in this leaflet cannot be applied to any other medicine, even those that are similar or appear to contain the same ingredients. What Zovirax is used for Zovirax is used for the treatment of shingles, which is also known as herpes zoster. Shingles is caused by the same virus which causes chicken pox. It usually involves nerve pain and a blistery rash, limited to one area of the body. How does Zovirax work? Aciclovir (the active ingredient in Zovirax) belongs to a group of medicines called "anti-virals". Zovirax works by stopping the production of the shingles virus. This reduces the length and severity of an outbreak of shingles. Zovirax does not get rid of the virus from your body. Your doctor may, however, have prescribed Zovirax for a different use to that described above. If you have any questions about why you are taking Zovirax ask your doctor or pharmacist. Your doctor or pharmacist will be able to provide you with more information. Before you use Zovirax Zovirax is not suitable for everyone. Be sure that your doctor knows about the following before you take Zovirax:
1. If you are allergic to:
Aciclovir (the active ingredient in Zovirax) or Valaciclovir;
Any other ingredient listed at the end of this leaflet.
2. If you are pregnant, or become pregnant while using Zovirax, or are breastfeeding.
3. If you suffer from:
A kidney or liver condition; or
A blood condition, or
A nerve disease.
4. If you are taking any other medication such as probenecid or diuretics (fluid tablets), including medicines that you buy without a prescription from a pharmacy, supermarket or health food shop.
Your doctor or pharmacist will have a complete list of the medicines that may cause problems when taken with Zovirax. When you must not use Zovirax Do not use Zovirax after the expiry date printed on the pack. Do not use Zovirax if the packaging shows signs of tampering. Do not use Zovirax to treat any other conditions unless advised by your doctor. Do not give Zovirax to anyone else, even if their symptoms seem similar to yours. Using Zovirax Take Zovirax as directed by your doctor or pharmacist. Never change the dose yourself. Your doctor and pharmacist will be able to tell you:
how many tablets to take at each dose;
how many doses to take each day
when to take each of your doses.
The label on the pack that the tablets were supplied in will give the same information. If there is something that you do not understand, ask either your doctor or pharmacist. The usual dose of Zovirax in the treatment of shingles is one 800mg tablet every four hours while awake (equivalent to five tablets daily) for seven days. Your doctor may vary your Zovirax dosage if you also suffer from other medical conditions. If you have any questions about the dose that you have been prescribed, you should ask your doctor or pharmacist. How to take Zovirax Your Zovirax tablets may be swallowed whole with a glass of water, or dispersed in a quarter of a glass of water (about 50ml) and then swallowed. If you forget to take your dose If you have just missed your scheduled dose, take it as soon as you remember and continue as before. If you have forgotten to take one dose of Zovirax and it is almost time to take your next scheduled dose, then skip the dose you have missed, and continue taking your Zovirax as directed by your doctor or pharmacist. If you have forgotten to take more than one dose, contact your doctor or pharmacist for advice. Do not take a double dose to makeup for the dose that you have missed. If you have trouble remembering when to take your medicine, ask your pharmacist for some hints. In case of overdose Immediately contact your doctor or Poisons Information Centre for advice, or go to Casualty at your nearest hospital, if you think that you may have taken too much, or if anyone else has taken any Zovirax. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention. Keep telephone numbers for these places handy. When to stop taking Zovirax Do not stop taking Zovirax just because you feel better. It is important that you complete your course of tablets to effectively treat the shingles. Your doctor will advise you when to stop taking Zovirax. If you are unsure whether you should stop taking Zovirax, talk to your doctor or pharmacist. While you are using Zovirax Drink plenty of fluids. Your doctor or pharmacist will be able to tell you whether there are any special instructions while you are taking Zovirax. See your doctor if you feel that your condition is not improving or getting worse. Side Effects All medicines can have some side effects. Sometimes they are serious. Most of the time they are not. Zovirax helps most people with shingles. In a few people, it may have some unwanted side effects. Be sure that your doctor or pharmacist knows as soon as possible if you do not feel well while you are taking Zovirax. Often it is difficult to tell the difference between side effects of medication and symptoms of the underlying illness. Tell your doctor if you notice any of the following:
Nausea, vomiting, headache.
Less common side effects include:
Diarrhoea, dizziness, tiredness, fever, confusion, sleep disturbances;
Weight loss, constipation, fluid retention, leg and joint pain, shakiness, hallucinations;
Taste disturbances, sore throat, skin rash.
A small number of patients have had other unwanted effects after taking Zovirax. There is no evidence that Zovirax is addictive. Ask your doctor or pharmacist to answer any questions you may have. After using Zovirax If your doctor advises you to stop taking Zovirax, ask your pharmacist what to do with any remaining tablets. Storage Keep your tablets in the pack that they were supplied in. Keep Zovirax in a cool, dark and dry place where the temperature stays below 30 °C. Do not store Zovirax in the bathroom or near a sink. Heat and dampness may effect Zovirax. Keep Zovirax, and all other medicines, where children cannot reach them. Do not leave Zovirax in the car on hot days. Product Description What Zovirax looks like
