What is ZYLOPRIM

The name of your medicine is ZYLOPRIM and is available in tablets of two different strengths.

The active ingredient is called allopurinol.

Allopurinol belongs to a group of medicines called anti-uricaemic agents and is used to reduce the amount of uric acid in the body. Most commonly, high levels of uric acid in the body are related to gout.

ZYLOPRIM is available as a 100 mg and 300 mg tablet.

What ZYLOPRIM is used for

ZYLOPRIM is used to treat high levels of uric acid in the blood (hyperuricaemia) associated with gout or some other conditions. Your doctor will identify these other conditions if necessary, as they are very uncommon (e.g. Lesch-Nyhan Syndrome).

Your doctor however, may have prescribed ZYLOPRIM for another purpose not listed above.

Ask your doctor if you have any questions about why ZYLOPRIM has been prescribed for you.

If you have any concerns, you should discuss this with your doctor.

This medicine is only available with a doctor’s prescription.

  2. You are breastfeeding or plan to breastfeed.

How to take ZYLOPRIM

How much to take

The dose of ZYLOPRIM may be different for each person and their medical condition. Your doctor will decide the right dose for you.

The recommended doses are for:

  • Adults: Usually 100 mg to 600 mg daily in divided doses (that is one 100 mg tablet daily up to one 300 mg tablet twice daily), but the dose may be as much a 900 mg daily to treat very high blood levels of uric acid.
  • Children under 15 years: 100 mg to 400 mg daily in divided doses.
  • Elderly patients usually receive the lowest dose possible to control uric acid production.

How to take ZYLOPRIM

Swallow the tablets with plenty of water and after food to reduce the possibility of gastric upset.

When to take it

Take ZYLOPRIM immediately after meals at the frequency directed by your doctor. For example, morning and night, after breakfast and dinner for a twice daily dosage.

If you forget to take it

If your dosing schedule is one dose a day, take the missed dose as soon as possible, but not later than 4 hours before your next dose.

If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.

Otherwise, take it as soon as you remember, and then go back to taking it as you would normally.

Do not take a double dose to make up for the dose that you missed.

Speak to your doctor or pharmacist if you are unsure about whether to take your next dose.

Do not try to make up for missed doses by taking more than one dose at a time. This may increase the chance of you getting an unwanted side effect.

If you have trouble remembering when to take your medicine, ask your pharmacist for some hints.

If you take too much (Overdose)

Immediately telephone your doctor or Poisons Information Centre (telephone 13 11 26) for advice, or go to Accident and Emergency at your nearest hospital, if you think that you or anyone else may have taken too much ZYLOPRIM.
