What allopurinol is used for

The name of your medicine is APO-Allopurinol. It contains the active ingredient, allopurinol.
Allopurinol is used to treat:
gouty arthritis or gout
kidney stones
rare conditions where high levels of uric acid occur in the blood (for example, Lesch-Nyhan syndrome).
Allopurinol is used to treat the symptoms of these conditions, but it will not cure them. Also, it will not help treat the pain that occurs in an acute attack of gout.

How it works

Allopurinol belongs to a group of medicines called anti-uricaemic agents. These medicines work by reducing high levels of uric acid in the body, which are usually due to gout. Excess amounts of uric acid in the blood may lead to uric acid crystals being made and deposited in the joints, thereby causing pain, swelling and tenderness.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed allopurinol for another reason.
This medicine is available only with a doctor's prescription.
There is no evidence that this medicine is addictive.

Use in children

There is very little information to recommend the use of this medicine in children. Allopurinol should only be taken by children if a doctor has prescribed it.

Do not take this medicine if the packaging is torn, shows signs of tampering or if the tablets do not seem quite right

3.are having an attack of gout.

Taking other medicines

Tell your doctor or pharmacist if you are taking any other medicines, including any that you buy without a prescription from your pharmacy, supermarket or health food shop.
Some medicines and allopurinol may interfere with each other. These include:
some medicines used to treat high blood pressure or heart problems
thiazide diuretics (a certain type of water tablet)
mercaptopurine, azathioprine or cyclosporin - medicines used to suppress the immune system
aspirin and other medicines known as salicylates
probenicid, a medicine used to treat gout
warfarin, used to help prevent blood clots
chlorpropamide, a medicine used to treat diabetes
phenytoin, a medicine used to treat epilepsy
certain antibiotics such as ampicillin and amoxycillin
theophylline, a medicine used to treat asthma
vidarabine, an anti-viral medicine.
These medicines may be affected by allopurinol or may affect how well it works. You may need different amounts of your medicine, or you may need to take different medicines.
Your doctor and pharmacist can tell you if you are taking any of these medicines. They may also have more information on medicines to be careful with or avoid while taking allopurinol.
Other interactions not listed above may also occur.

How to take this medicine

Follow all directions given to you by your doctor or pharmacist carefully.
They may be different to the information in this leaflet.
If you do not understand any written instructions, ask your doctor or pharmacist for help.

How much to take

Your doctor or pharmacist will tell you how many tablets you need to take. This depends on your condition and whether or not you are taking any other medicines.
The usual adult dose range is:100 - 200 mg per day for mild conditions
300 - 600mg per day for moderately severe conditions
700 - 900mg per day for severe conditions.
People over 65 years of age, and those with kidney and/or liver problems should be started on the lowest dose possible to control uric acid production.
Children under 15 years of age usually take 100 - 400 mg per day.

How to take it

Swallow the tablets with a glass of water.

When to take it

Take your medicine immediately after food, as this will lessen the chance of a stomach upset.
Take your medicine at the same time each day.
Taking your medicine at the same time each day will have the best effect. It will also help you remember when to take it.
Allopurinol is usually taken once daily. However, if your dose is more than 300 mg, your doctor may advise you to take your medicine twice a day. Then, it should be taken morning and night, after breakfast and dinner.

How long to take it for

Continue taking your medicine for as long as your doctor tells you.
Allopurinol helps to control the symptoms of your condition but does not cure it. It is important to keep taking your medicine, even if you feel well.

If you forget to take it

If you miss a dose, and it is more than 4 hours until your next dose is due, take the missed dose as soon as you remember.
If it is less than 4 hours to your next dose, do not take the dose you missed and take your next dose when you
are meant to.
Then go back to taking your medicine as you would normally. Do not take a double dose to make up for the dose that you missed. This may increase the chance of you getting an unwanted side effect.
If you are not sure what to do, ask your doctor or pharmacist.
If you have trouble remembering to take your medicine, ask your pharmacist for some hints.

If you take too much (overdose)

Immediately telephone your doctor or pharmacist or the Poisons Information Centre (telephone 13
11 26), or go to Accident and Emergency Department at your nearest hospital, if you think that you or anyone else may have taken too many allopurinol.
Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

following:
nausea
vomiting
diarrhoea
dizziness.
