Table of contents:

Relafen (Nabumetone) is a non-steroidal anti-inflammatory drug (NSAID) used in the treatment of osteoarthritis and rheumatoid arthritis. It helps reduce pain, swelling, and joint stiffness associated with these conditions. It works by blocking the production of hormones that cause pain and inflammation in the body.

Nabumetone can be taken orally or applied directly to the affected area through a topical form. It exhibits anti-inflammatory, analgesic, and antipyretic properties, and is known to reduce pain, swelling, and joint stiffness commonly associated with arthritis. Compared to other similar medications in its class, Nabumetone is associated with a lower risk of stomach-related side effects.

Uses and Dosage

To take Nabumetone, you should take it orally as a tablet, usually once or twice daily, with or without food. Do not lie down for at least 10 minutes after taking this drug. To prevent stomach upset, take it with food, milk, or an antacid.

If there is anything you do not understand about taking Nabumetone, ask your doctor or pharmacist to explain it to you. Take it at the same time every day and follow the directions on your prescription label carefully and do not take more or less of it or take it more often than prescribed.

  • For osteoarthritis and rheumatoid arthritis, Nabumetone is usually prescribed at a starting dose of 1000mg to be taken once or twice daily with or without food. Some patients may benefit from an increased dose of 1500mg to 2000mg per day.
  • To reduce the risk of renal effects, the lowest effective dose should be used for chronic treatment. Patients weighing less than 50kg may not require dosages beyond 1000mg, so adjustments to the dose should be made based on the individual patient's response to initial therapy.
