Diclofenac for pain and inflammation

About diclofenac

Diclofenac is a type of anti-inflammatory painkiller called non-steroidal anti-inflammatory drugs (NSAIDs), or just 'anti-inflammatories'.

It is used to treat painful conditions such as arthritis, sprains and strains, gikt, migrän, dental pain, and pain after surgical operations. It eases pain and reduces inflammation.

Types of diclofenac

There are two forms of diclofenac - diclofenac sodium and diclofenac potassium. The main difference between the two is that diclofenac potassium is absorbed into the body more quickly than diclofenac sodium.

A quick action is useful where immediate pain relief is required, and a prolonged action is more useful in reducing inflammation.

Diclofenac is also formulated as skin gels and patches and as eye drops.

Some brands of diclofenac also contain a medicine called misoprostol. Misoprostol helps to protect the stomach against irritation which can be caused by taking diclofenac over a period of time.

Diclofenac works by blocking the effect of chemicals in your body, called cyclo-oxygenase (COX) enzymes. These enzymes help to make other chemicals in the body, called prostaglandins.

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.

Common side effects of diclofenac are:

• Indigestion.

• Heartburn (acid reflux).

• Magont.

• Illamående.

• Diarré.

You will find a full list in the manufacturer's information leaflet supplied with your medicine.

The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.

If you experience any other symptoms which you think may be due to diclofenac, speak with your doctor or pharmacist for further advice.

Some medicines aren’t suitable for everyone. Before taking diclofenac, it’s important your doctor knows:

• Om du har astma eller någon annan allergisk sjukdom.

• If you have ever had a stomach or duodenal ulcer, or if you have an inflammatory bowel disorder such as Crohn's disease or ulcerös kolit.

• Om du har en hjärtsjukdom eller problem med dina blodkärl eller cirkulation.

• Om du är gravid eller ammar.

• If you have any risk factors for heart disease, including high blood pressure (hypertension), high cholesterol levels, diabetes or smoking.

• If you have any blood clotting problems.

• If you have a connective tissue disorder, such as a condition called systemic lupus erythematosus (SLE).

• If you have problems with the way your liver works, or problems with the way your kidneys work.

• Om du tar några andra läkemedel. Detta inkluderar alla läkemedel du tar som finns att köpa utan recept, samt växtbaserade och komplementära läkemedel.

• If you have ever had an allergic reaction to any other NSAID (such as aspirin, naproxen, indometacin, and ibuprofen), or to any other medicine.

• Before taking diclofenac, read the leaflet inside the pack for important information and possible side effects.

• Take diclofenac exactly as prescribed by your doctor or pharmacist. Follow the dose and timing on the label.

• Taking diclofenac with food or milk can help reduce stomach upset.

• Diclofenac comes in different forms. Follow the instructions for your specific type. Some tablets should be mixed with water, while others must be swallowed whole.

• If you miss a dose, take it when you remember unless it’s nearly time for the next dose. Do not take two doses at once.

• If using diclofenac mouthwash, rinse or gargle 15 ml two to three times a day. Use it for up to 7 days after dental treatment or 6 weeks after radiotherapy.

• Your doctor will prescribe the lowest effective dose for the shortest time to reduce side effects. If you need diclofenac long term, you may be given another medicine to help protect your stomach.

• Keep any regular doctor appointments so your progress can be checked, especially with long-term use.

• If you have asthma and develop wheezing or breathing problems, stop taking diclofenac and see your doctor straight away.

• Check with a pharmacist before taking other medicines. Do not take diclofenac with other anti-inflammatory painkillers, including some cold and flu remedies.

• If you’re having surgery or dental treatment, tell them you are taking diclofenac.

• Förvara alla läkemedel utom räckhåll och synhåll för barn.

• Förvara på en sval, torr plats, borta från direkt värme och ljus.
