Lopurin Side Effects

What should I watch for?

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.
