Take the Gout Quiz

What is febuxostat, and how does it work (mechanism of action)?

Febuxostat is a xanthine oxidase inhibitor used for treating gout caused by excessive levels of uric acid in the blood (hyperuricemia). Uric acid is formed from the breakdown of certain chemicals (purines) in the body. Hyperuricemia occurs when the body produces more uric acid than it can eliminate. The uric acid forms crystals in joints (gouty arthritis) and tissues, causing inflammation and pain. Elevated blood uric acid levels also can cause kidney disease and kidney stones. Febuxostat prevents the production of uric acid by blocking the activity of the enzyme (xanthine oxidase) that converts purines to uric acid. Uric acid levels may fall to target treatment levels within two weeks. Febuxostat and allopurinol (Zyloprim) are similar in how they work, but the maximum dose of febuxostat is more effective in reducing uric acid levels. The FDA approved febuxostat in February 2009.

What is the dosage for febuxostat?

The recommended dose is 40 or 80 mg daily. It may be administered with or without food, and it can be taken with antacids. Flares of gout may increase after febuxostat is started as uric acid moves out of tissues. These gout flares may be prevented with non-steroidal anti-inflammatory drugs (for example, indomethacin [Indocin, Indocin-SR]) or colchicine.

Which drugs or supplements interact with febuxostat?

Febuxostat may increase blood levels of mercaptopurine (Purinethol), azathioprine (Imuran), and theophylline (Theo-Dur, Respbid, Slo-Bid, Theo-24, Theolair, Uniphyl, Slo-Phyllin) by reducing their breakdown in the body. Therefore, febuxostat should not be administered with mercaptopurine, azathioprine, and theophylline.

Is febuxostat safe to take if I'm pregnant or breastfeeding?

There are no adequate studies of febuxostat in pregnant women.

It is not known whether febuxostat is excreted in human milk.

What preparations of febuxostat are available?

Tablets: 40 and 80 mg

How should I keep febuxostat stored?

Febuxostat should be stored at room temperature between 15 C to 30 C (59 F to 86 F).
