What is febuxostat?

Febuxostat reduces the production of uric acid in your body. A build-up of uric acid can cause gout symptoms.

Febuxostat is used to keep uric acid levels from getting to high in people with gout.

Febuxostat is for use only in people who cannot take another medicine called allopurinol, or when allopurinol has stopped working.

Febuxostat may also be used for purposes not listed in this medication guide.

Important Information

Taking febuxostat may 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 febuxostat if you also use azathioprine or mercaptopurine.

Before taking this medicine

You should not use febuxostat if you are allergic to it, or if you also use:

  • azathioprine; or

  • mercaptopurine.

Taking febuxostat may increase your risk of serious or fatal heart problems. Talk with your doctor about the risks and benefits of febuxostat.

Tell your doctor if you have ever had:

  • heart problems;

  • a heart attack or stroke;

How should I take febuxostat?

Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed.

You may take febuxostat with or without food. Febuxostat may be taken with an antacid if needed.

You may have an increase in gout symptoms (flares) when you first start taking febuxostat. Your doctor may prescribe other medications for you to use during the first 6 months of treatment with febuxostat.

You should not stop using febuxostat suddenly. Stopping suddenly may make your condition worse.

For best results, keep using your medications as directed. Call your doctor if your symptoms do not improve after 6 months, or if they get worse.

You will need frequent blood tests to check your liver function.

Store at room temperature away from moisture, heat, and light.

What should I avoid while taking febuxostat?

Follow your doctor's instructions about any restrictions on food, beverages, or activity.
