Drug class: Antihyperuricemic agents

What is Uloric?

Uloric reduces the production of uric acid in your body. A build-up of uric acid can cause gout symptoms. Uloric is used to keep uric acid levels from getting to high in people with gout. Uloric is for use only in people who cannot take another medicine called allopurinol, or when allopurinol has stopped working.


Taking Uloric increase your risk of serious or fatal heart problems. Seek medical attention if you have chest pain, trouble breathing, fast heartbeats, sudden severe headache, numbness or weakness on one side of your body, or problems with vision or speech. You should not use Uloric if you also use azathioprine or mercaptopurine.

Before taking Uloric, tell your doctor if you have kidney disease, liver disease, diabetes, heart disease, cancer, Lesch-Nyhan syndrome, a history of heart attack or stroke, or if you have ever received an organ transplant.

You may have an increase in gout symptom flares when you first start taking Uloric. For best results, keep taking the medication as directed. Your doctor may prescribe other gout medications for you to use during the first 6 months of treatment. To be sure Uloric is helping your condition, your blood may need to be tested often. Visit your doctor regularly.
