About aceclofenac

Type of medicineNon-steroidal anti-inflammatory drug (NSAID)
Used forRelief of pain and inflammation in osteoarthritis, rheumatoid arthritis and ankylosing spondylitis
Also calledPreservex®
Available asTablets

Aceclofenac is used to relieve the pain and inflammation caused by rheumatoid arthritis, osteoarthritis or ankylosing spondylitis. It works by blocking a substance in the body called cyclo-oxygenase (also known as COX) which is involved in the production of irritant chemicals in conditions such as arthritis. By blocking the action of COX, aceclofenac reduces the symptoms of pain and inflammation.

Before taking aceclofenac

Before taking aceclofenac make sure your doctor or pharmacist knows:

  • If you are pregnant, trying for a baby or breast-feeding.
  • If you are under 18 years of age or over 65 years of age.
  • If you have liver or kidney problems.
  • If you have asthma or any other allergic disorder.
  • If you have ever had a stomach or duodenal ulcer.
  • If you have heart problems.
  • If you have ever had blood clotting problems.
  • If you have blood in your stools.
  • If you have a rare blood disorder known as porphyria.
  • If you have systemic lupus erythematosus (an inflammatory condition also called lupus or SLE).
  • If you are taking other medicines, including those available to buy without a prescription, herbal and complementary medicines.
  • If you have ever had an allergic or unusual reaction to any other NSAID (this includes aspirin, naproxen, diclofenac and ibuprofen) or to any other medicine.

  • Before starting aceclofenac, read the manufacturer's printed information leaflet from inside the pack.
  • Take aceclofenac exactly as your doctor has told you.
  • The usual dose is one tablet in the morning and one in the evening. Take aceclofenac tablets with plenty of water, during or straight after a meal.
  • Try to take your doses of aceclofenac at the same times each day to avoid missing any doses.
  • If you forget to take a dose, take it as soon as you remember unless it is nearly time for your next dose, in which case leave out the missed dose. Do not take two doses together to make up for a missed dose.

Getting the most from your treatment

  • Keep your regular doctor's appointments so your progress can be monitored.
  • If you need to take aceclofenac for a long time, your doctor may want to prescribe another medicine along with it to protect your stomach from irritation.
