Nabumetone is in a group of drugs called nonsteroidal anti-inflammatory drugs (NSAIDs). Nabumetone works by reducing hormones that cause inflammation and pain in the body.

Nabumetone is used to treat pain or inflammation caused by arthritis.

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

This medicine can increase your risk of life-threatening heart or circulation problems, including heart attack or stroke. This risk will increase the longer you use nabumetone. Do not use this medicine just before or after having heart bypass surgery (also called coronary artery bypass graft, or CABG).

Seek emergency medical help if you have symptoms of heart or circulation problems, such as chest pain, weakness, shortness of breath, slurred speech, or problems with vision or balance.

This medicine can also increase your risk of serious effects on the stomach or intestines, including bleeding or perforation (forming of a hole). These conditions can be fatal and gastrointestinal effects can occur without warning at any time while you are taking nabumetone. Older adults may have an even greater risk of these serious gastrointestinal side effects.

Call your doctor at once if you have symptoms of bleeding in your stomach or intestines. This includes black, bloody, or tarry stools, or coughing up blood or vomit that looks like coffee grounds.

Do not use any other over-the-counter cold, allergy, or pain medication without first asking your doctor or pharmacist. Many medicines available over the counter contain aspirin or other medicines similar to nabumetone (such as ibuprofen, ketoprofen, or naproxen). If you take certain products together you may accidentally take too much of this type of medication. Read the label of any other medicine you are using to see if it contains aspirin, ibuprofen, ketoprofen, or naproxen.

Do not drink alcohol while taking nabumetone. Alcohol can increase the risk of stomach bleeding caused by nabumetone.

Avoid exposure to sunlight or artificial UV rays (sunlamps or tanning beds). Nabumetone can make your skin more sensitive to sunlight and sunburn may result.

Taking an NSAID can increase your risk of life-threatening heart or circulation problems, including heart attack or stroke. This risk will increase the longer you use an NSAID. Do not use this medicine just before or after having heart bypass surgery (also called coronary artery bypass graft, or CABG).

NSAIDs can also increase your risk of serious effects on the stomach or intestines, including bleeding or perforation (forming of a hole). These conditions can be fatal and gastrointestinal effects can occur without warning at any time while you are taking an NSAID. Older adults may have an even greater risk of these serious gastrointestinal side effects.

Do not use this medication if you are allergic to nabumetone, or if you have a history of allergic reaction to aspirin or other NSAIDs.

Before taking nabumetone, tell your doctor if you are allergic to any drugs, or if you have:

• a history of heart attack, stroke, or blood clot;

• heart disease, congestive heart failure, high blood pressure;

• a history of stomach ulcers or bleeding;

• liver or kidney disease,

• asthma;

• polyps in your nose;

• a bleeding or blood clotting disorder; or

If you have any of these conditions, you may need a dose adjustment or special tests to safely take nabumetone.
