Nabumetone: 6 things you should know

Medically reviewed by C. Fookes, BPharm Last updated on Jan 29, 2019.

1. How it works

  • Nabumetone helps relieve pain and inflammation by blocking the effects of COX enzymes. This prevents prostaglandin synthesis (prostaglandins elevate body temperature and make nerve endings more sensitive to pain transmission).
  • Nabumetone belongs to a group of medicines known as NSAIDs (nonsteroidal anti-inflammatory drugs).

2. Upsides

  • Nabumetone relieves inflammation and pain associated with osteoarthritis and rheumatoid arthritis in adults.
  • NSAIDs (such as nabumetone) are considered first-line options for mild-to-moderate arthritis-type pain because at correct dosages they are effective, do not cause dependence and are readily available at a low cost.
  • May be less likely than some other NSAIDs (such as naproxen) to adversely affect the stomach or increase bleeding time.
  • Can be given as a single or twice daily dose.
  • Generic nabumetone is available.

3. Downsides

If you are between the ages of 18 and 60, take no other medication or have no other medical conditions, side effects you are more likely to experience include:

  • Diarrhea, dyspepsia, abdominal pain, constipation, flatulence, or nausea.
  • Tinnitus, edema, itchiness and a rash have also been reported.
  • Stomach-related adverse effects such as bleeding, ulceration, or perforation. Older patients or those taking other medicines that affect the stomach may be more at risk.
  • Most NSAIDs have been associated with an increased risk of stroke or heart attack. The risk may be higher for patients with pre-existing conditions, in those who drink more than three glasses of alcohol per day, and with higher dosages.
  • May not be suitable for some people including those with kidney disease, a history of stomach ulcers or other gastrointestinal disorders, with pre-existing cardiovascular disease, or following coronary artery bypass graft surgery.
  • May interact with some other medicines such as warfarin, SSRIs, ACE inhibitors, and diuretics.

Notes: In general, seniors or children, people with certain medical conditions (such as liver or kidney problems, heart disease, diabetes, seizures) or people who take other medications are more at risk of developing a wider range of side effects.

4. Bottom Line

Nabumetone helps relieve pain associated with rheumatoid arthritis or osteoarthritis. It can be taken as a single daily dose and appears less likely to cause stomach-related side effects than some other NSAIDs.

5. Tips

  • Take with food to reduce the risk of stomach-related adverse effects. See a doctor if you experience any persistent stomach-related adverse effects.
  • Always use the lowest effective dose for the shortest duration possible, or as advised by your doctor.
  • Response to different NSAIDs can vary so switching types (ie, from nabumetone to ibuprofen) may improve response.
  • See a doctor immediately if you experience any difficulty with breathing, unexplained sickness or fatigue, loss of appetite, vision changes, fluid retention or abnormal bleeding.
  • NSAIDs should not be used in the last 3 months of pregnancy; ask your doctor before using any medication in pregnancy.
  • Avoid if you experience a worsening of asthma or develop hives with nabumetone or any other NSAID use, including aspirin.
  • Do not use this medicine in the setting of heart bypass surgery (coronary artery bypass graft, or CABG).
  • See a doctor immediately if you experience any difficulty with breathing, unexplained sickness or fatigue, loss of appetite, vision changes, fluid retention or abnormal bleeding.

6. Response and Effectiveness

  • Peak levels of nabumetone are reached 1-2 hours after administration. The effects of one nabumetone tablet generally last for 24 hours.
