1 What Naproxen tablets are and what they are used for

Naproxen tablets are used to treat:

  • diseases of joints such as rheumatoid arthritis (including in children), osteoarthritis, ankylosing spondylitis. Naproxen cannot cure arthritis but is used to give relief of some symptoms such as inflammation, swelling, stiffness and joint pain
  • attacks of gout
  • muscle and bone disorders
  • painful periods.

  • are allergic to aspirin or other non-steroidal anti-inflammatory medicines (NSAIDs), or you have developed signs of asthma (wheezing), runny nose, swelling of the skin or rash when taking these medicines
  • have or have had stomach or duodenum (gut) ulcers, bleeding in the stomach or intestines (gastrointestinal bleeding) or have had two or more episodes of peptic ulcers, stomach bleeding or perforation
