Ketoprofen is a medicine called a non-steroidal anti-inflammatory drug. It is also known as an 'NSAID'.
Tell your doctor if you have ever had an allergic reaction to any other anti-inflammatory medicine.
Take ketoprofen capsules with food.
|Type of medicine||A non-steroidal anti-inflammatory drug (NSAID)|
|Used for||Relief of pain and inflammation, particularly in arthritis and other muscle and joint conditions|
|Also called||Larafen®; Oruvail®|
|Available as||Prolonged-release capsules|
Anti-inflammatory painkillers like ketoprofen are also called non-steroidal anti-inflammatory drugs (NSAIDs), or sometimes just 'anti-inflammatories'. Ketoprofen eases pain and swelling (inflammation) in conditions like arthritis, sprains and strains, and gout, and it may also be used for pain relief for period (menstrual) pain, and after surgical operations.
Ketoprofen works by blocking the effect of natural chemicals called cyclo-oxygenase (COX) enzymes. These enzymes help to make other chemicals, called prostaglandins, in the body. 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.
Ketoprofen is also available as a gel which can be applied directly to your skin to help relieve muscle and joint pain. There is more information about this in a separate leaflet called Ketoprofen gel for pain relief.
Before taking ketoprofen
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 ketoprofen, 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 breastfeeding.
- 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 a heart condition or a problem with your blood vessels or circulation.
- If you have high blood pressure (hypertension).
- If you have any blood clotting problems.
- If you have diabetes (diabetes mellitus) or high cholesterol levels.
- 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 are taking any other medicines. This includes any medicines you are taking which are available to buy without a prescription, as well as as herbal and complementary medicines.
- If you have ever had an allergic reaction to any other NSAID (such as aspirin, ibuprofen, diclofenac, and indometacin), or to any other medicine.
How to take ketoprofen
- Before you start taking ketoprofen, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about the capsules and provide a full list of the side-effects which you could experience from taking them.
- Take ketoprofen exactly as your doctor tells you to. Ketoprofen prolonged-release capsules release the medicine slowly over the day to give an even and prolonged effect. Take one dose a day. There are two strengths of prolonged-release capsule available: 100 mg and 200 mg. Your doctor will prescribe the strength of capsule which is right for you.
- Take the capsule with a snack or just after eating a meal. Swallow the capsule whole - do not chew or open the capsule.
- Try to take the capsule at the same time of day each day as this will help you to remember to take it.
- If you forget to take the capsule at your usual time, take it as soon as you remember. If you do not remember until the following day, leave out the forgotten dose from the previous day and take the dose that is due as normal. Do not take two doses at the same time 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 ketoprofen for a long time, your doctor may also want to prescribe another medicine for you to take along with ketoprofen to protect your stomach from irritation.
- Try to keep any regular appointments with your doctor. This is so your doctor can check on your progress, and is especially important if you are taking ketoprofen for a long-term condition.
- If you are taking ketoprofen for gout and your symptoms have not improved within seven days, you should let your doctor know about this.
- If you have asthma, symptoms such as wheeze or breathlessness can be made worse by anti-inflammatories such as ketoprofen. If this happens to you, you should stop taking the capsules 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 suitable for you to take. This is because you should not take ketoprofen 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.
