Aceclofenac is a medicine called a non-steroidal anti-inflammatory drug. It is also known as 'an NSAID'.
Before you take aceclofenac, tell your doctor if you have ever had an allergic reaction to any other anti-inflammatory painkiller.Take one tablet in the morning and one in the evening. Take the tablets during a meal, or after a snack.
|Type of medicine||A non-steroidal anti-inflammatory drug (NSAID)|
|Used for||Relief of pain and inflammation in adults with arthritis or ankylosing spondylitis|
Anti-inflammatory painkillers like aceclofenac are also called non-steroidal anti-inflammatory drugs (NSAIDs), or sometimes just 'anti-inflammatories'. Aceclofenac is prescribed for people with painful rheumatic conditions such as osteoarthritis, rheumatoid arthritis and ankylosing spondylitis. It eases pain and reduces inflammation.
Aceclofenac works by blocking the effect of natural substances 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 can 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 ever had an allergic reaction to any other NSAID (such as aspirin, naproxen, diclofenac, and indometacin), or to any other medicine.
- If you have ever had a problem with stomach or duodenal bleeding, such as if you have had an ulcer.
- If you have asthma or any other allergic disorder.
- If you have a heart condition, or a problem with your blood vessels or circulation.
- If you are pregnant, trying for a baby, or breast-feeding.
- If you have any problems with the way your liver works, or if you have any problems with the way your kidneys work.
- If you have high blood pressure.
- If you have ever had blood clotting problems.
- If you have an inflammatory bowel disorder such as Crohn's disease or ulcerative colitis.
- If you have a connective tissue disorder such as systemic lupus erythematosus. This is an inflammatory condition which is also called lupus or SLE.
- If you have a rare inherited 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, as well as herbal and complementary medicines.
How to take aceclofenac
- Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about aceclofenac, and it will also provide you with a full list of the side-effects which you could experience from taking it.
- Take aceclofenac exactly as your doctor tells you to. The usual dose is one 100 mg tablet twice daily, taken preferably morning and evening.
- Take aceclofenac with food; during a mealtime is ideal. This will help to protect your stomach from side-effects such as indigestion and stomach irritation.
- Swallow the tablet with a drink of water. Do not chew or crush 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 take the next dose when it is due and leave out the forgotten 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 in order to reduce the risk of side-effects. If you need to take aceclofenac over a period of 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.
- There is known to be a small increased risk of heart and blood vessel problems in people taking some anti-inflammatory painkillers long-term. Your doctor will explain this to you and will prescribe the lowest suitable dose for the shortest time in order to reduce the risk. Do not take more than the recommended dose.
- 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 due to have an operation or dental treatment, tell the person carrying out the treatment which medicines you are taking.
