How to Use allopurinol
Take this medicine by mouth with a glass of water. Follow the directions on the prescription label. If this medicine upsets your stomach, take it with food or milk. Take your doses at regular intervals. Do not take your medicine more often than directed.
Talk to your pediatrician regarding the use of this medicine in children. Special care may be needed. While this drug may be prescribed for children as young as 6 years for selected conditions, precautions do apply.
They need to know if you have any of these conditions:
- kidney or liver disease
- an unusual or allergic reaction to allopurinol, other medicines, foods, dyes, or preservatives
- pregnant or trying to get pregnant
- breast feeding
If you miss a dose, take it as soon as you can. If it is almost time for your next dose, take only that dose. Do not take double or extra doses.
Visit your doctor or health care professional for regular checks on your progress. If you are taking this medicine to treat gout, you may not have less frequent attacks at first. Keep taking your medicine regularly and the attacks should get better within 2 to 6 weeks. Drink plenty of water (10 to 12 full glasses a day) while you are taking this medicine. This will help to reduce stomach upset and reduce the risk of getting gout or kidney stones.
Call your doctor or health care professional at once if you get a skin rash together with chills, fever, sore throat, or nausea and vomiting, if you have blood in your urine, or difficulty passing urine.
Do not take vitamin C without asking your doctor or health care professional. Too much vitamin C can increase the chance of getting kidney stones.
You may get drowsy or dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how this drug affects you. Do not stand or sit up quickly, especially if you are an older patient. This reduces the risk of dizzy or fainting spells. Alcohol can make you more drowsy and dizzy. Alcohol can also increase the chance of stomach problems and increase the amount of uric acid in your blood. Avoid alcoholic drinks.
Keep out of the reach of children.
Store at room temperature between 15 and 25 degrees C (59 and 77 degrees F). Protect from light and moisture. Throw away any unused medicine after the expiration date.
