Naproxen Tablets contain naproxen, a non-steroidal anti-inflammatory drug (NSAID) used to relieve pain, reduce inflammation and help manage swelling associated with certain medical conditions.

Naproxen works by reducing the production of prostaglandins, substances involved in pain and inflammation. It may be prescribed for short-term painful conditions or as part of the management of longer-term inflammatory disorders.

Naproxen is used for a range of conditions, including:

  • Period pain (dysmenorrhoea): Helps relieve menstrual cramps and associated discomfort.
  • Back pain: May help manage pain associated with certain acute musculoskeletal conditions, such as strains and lower back pain.
  • Joint and muscle pain: May be prescribed for inflammatory pain, sprains and strains.
  • Osteoarthritis: Helps relieve pain and inflammation associated with degenerative joint disease.
  • Rheumatoid arthritis: May help manage joint pain, swelling and stiffness as part of a wider treatment plan.
  • Acute gout: May help reduce pain and inflammation during a gout attack.
  • Ankylosing spondylitis: May help manage pain and stiffness associated with this inflammatory spinal condition.

Naproxen is not suitable for every type of pain, and treatment depends on the underlying cause, medical history and other medicines being taken.

Naproxen Tablets are available in 250mg and 500mg strengths, supplied in packs of 28 tablets.

A prescription is required for these products. Treatment is subject to a clinical assessment by an authorised prescriber, who will determine whether naproxen is appropriate and which strength, dose and duration should be used.

Active ingredient:

Naproxen.

  • Naproxen 250mg Tablets contain 250mg of naproxen per tablet.
  • Naproxen 500mg Tablets contain 500mg of naproxen per tablet.

Naproxen belongs to the NSAID group of medicines. It helps relieve pain and inflammation by inhibiting enzymes involved in prostaglandin production.

Other ingredients:

The inactive ingredients depend on the specific product formulation. Check the patient information leaflet supplied with your tablets, particularly if you have allergies or intolerances to ingredients such as lactose or tablet colourings.

The appropriate dosage of naproxen depends on the condition being treated, the strength prescribed and the patient's individual circumstances.
