Nabumetone Tablets belong to a group of medicines called non-steroidal anti-inflammatory drugs (known as NSAIDs).
They work by reducing the production of some natural chemicals found in the body. These chemicals (prostaglandins) cause the symptoms of inflammation such as pain and swelling.
Nabumetone Tablets are used to treat the pain, stiffness and swelling of joints which are affected by osteoarthritis or rheumatoid arthritis.
Such medicines include ibuprofen, diclofenac or naproxen. Some people who have had previous allergic reactions to NSAID medicines have very serious, sometimes fatal, reactions if they take this kind of medicine again.
If any of the above applies to you, talk to your doctor or pharmacist.
