Aceclofenac is a medicine called a non-steroidal anti-inflammatory drug. It is also known as 'an NSAID'.
Before you take aceclofenac, let your doctor know if you have ever had a bad reaction to any other anti-inflammatory painkiller.
Take one tablet in the morning and one in the evening. It is best to take the tablets straight after a meal or snack.
|Type of medicine||Non-steroidal anti-inflammatory drug (NSAID)|
|Used for||Relief of pain and inflammation|
Anti-inflammatory painkillers like aceclofenac are sometimes called non-steroidal anti-inflammatory drugs (NSAIDs), or just 'anti-inflammatories'. Aceclofenac is used to treat painful rheumatic conditions such as osteoarthritis, rheumatoid arthritis and ankylosing spondylitis. It eases pain and reduces inflammation.
Aceclofenac works by blocking the effect of chemicals called cyclo-oxygenase (COX) enzymes. These enzymes help to make other chemicals in the body, called prostaglandins. Some prostaglandins are produced at sites of injury or damage, and cause pain and inflammation. By blocking the effect of COX enzymes, fewer prostaglandins are produced, which means pain and inflammation are eased.
Before taking aceclofenac
Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking aceclofenac, it is important that your doctor knows:
- If you have asthma or any other allergic disorder.
- If you have ever had a stomach or duodenal ulcer, or if you have an inflammatory bowel disorder such as Crohn's disease or ulcerative colitis.
- If you are pregnant, trying for a baby, or breast-feeding.
- If you are under 18 or over 65 years of age.
- If you have liver or kidney problems.
- If you have a heart condition, or a problem with your blood vessels or circulation.
- If you have high blood pressure.
- If you have ever had blood clotting problems.
- If you have a connective tissue disorder, such as systemic lupus erythematosus (an inflammatory condition also called lupus, or SLE).
- If you have a rare blood disorder known as porphyria.
- If you are taking any other medicines. This includes any medicines you are taking which are available to buy without a prescription, such as herbal and complementary medicines.
- If you have ever had an allergic reaction to any other NSAID (such as aspirin, naproxen, diclofenac, and indometacin) or to any other medicine.
How to take aceclofenac
- Before you start taking aceclofenac, read the manufacturer's printed information leaflet from inside the pack. The manufacturer's leaflet will give you more information about the tablets and provide a full list of side-effects which you may experience from taking them.
- Take aceclofenac exactly as your doctor tells you to. The usual dose for adults is one 100 mg tablet taken twice daily, preferably morning and evening.
- Take your doses with a snack, or just after eating a meal. This will help protect your stomach from side-effects such as indigestion.
- Swallow the tablets whole with a drink of water. Do not chew or break the tablets.
- 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
- Your doctor will try to prescribe you the lowest dose for the shortest time to reduce the risk of side-effects. 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.
- Try to keep your regular appointments with your doctor. This is so your doctor can check on your progress.
- If you have asthma, symptoms such as wheeze or breathlessness can be made worse by anti-inflammatories such as aceclofenac. If this happens to you, you should stop taking the tablets and see your doctor as soon as possible.
- If you buy any medicines, check with a pharmacist that they are safe to take with an anti-inflammatory like aceclofenac. This is because you should not take these tablets with any other anti-inflammatory painkiller, some of which are available in cold and flu remedies which can be bought over the counter.
- If you are having an operation or dental treatment, tell the person carrying out the treatment which medicines you are taking.
