  • If you have asthma or have suffered attacks of asthma, acute allergic rhinitis (a short period of inflamed lining of the nose), nasal polyps (lumps within the nose due to allergy), urticaria (skin rash), angioedema (swollen face, eyes, lips, or tongue, or respiratory distress) or wheezing in the chest after taking aspirin or other non-steroidal anti-inflammatory medicines;
  • If you have or have suffered in the past from a peptic ulcer, stomach or bowel bleeding or have chronic digestive problems (e.g. indigestion, heartburn);

  • If you have serious heart failure, moderate or serious kidney problems or serious liver problems;
  • If you have a bleeding disorder or a blood clotting disorder;

Take special care with Keral:
  • If you suffer from allergy, or if you have had allergy problems in the past;
  • If you have kidney, liver or heart problems (hypertension and/or heart failure) as well as fluid retention, or have suffered from any of these problems in the past;
  • If you are taking diuretics or you suffer from very poor hydration and reduced blood volume due to an excessive loss of fluids (e.g. from excessive urination, diarrhoea or vomiting);
  • If you have heart problems, previous stroke or think that you might be at risk of these conditions (for example if you have high blood pressure, diabetes or high cholesterol or are a smoker) you should discuss your treatment with your doctor or pharmacist; medicines such as Keral may be associated with a small increased risk of heart attack (“myocardial infarction”) or stroke. Any risk is more likely with high doses and prolonged treatment. Do not exceed the recommended dose or duration of treatment.
  • If you are elderly: you may be more likely to suffer from side effects. If any of these occur, consult your doctor immediately;
  • If you are a woman with fertility problems (Keral may impair your fertility, therefore you should not take it if you are planning to become pregnant or you are doing fertility tests);
  • If you suffer from a disorder in the formation of blood and blood cells;

  • If you have suffered in the past from a chronic inflammatory disease of the bowel (ulcerative colitis, Crohn’s disease);
  • If you have or have suffered in the past from other stomach or bowel problems;
  • If you are taking other medicines that increase the risk of peptic ulcer or bleeding, e.g. oral steroids, some antidepressants (those of the SSRI type, i.e. Selective Serotonin Reuptake Inhibitors), agents that prevent blood clots such as aspirin or anticoagulants such as warfarin. In such cases, consult your doctor before taking Keral: he/she may want you to take an additional medicine to protect your stomach (e.g. misoprostol or medicines that block the production of stomach acid).

Taking Keral with food and drink

Take the tablets with an adequate amount of water. Take your tablets with food, as it helps to decrease the risk of stomach or bowel side effects. However, if you have acute pain, take the tablets on an empty stomach, i.e. at least 30 minutes before meals, as this helps the medicine start working a little faster.

Children and adolescents

Do not take Keral if you are less than 18 years of age.

Pregnancy and breast-feeding

Do not use Keral during pregnancy or when breast feeding.

Ask your doctor or pharmacist for advice before taking any medicine:

  • tell your doctor if you are pregnant or if you are planning to become pregnant, as Keral may not be right for you.
  • you must not take Keral if you are breast-feeding. Ask your doctor for advice.

Driving and using machines

Keral may slightly affect your ability to drive and handle machines, due to the possibility of dizziness or drowsiness as side effects of treatment. If you notice such effects, do not drive or use machines until the symptoms wear off. Ask your doctor for advice.


Always use Keral exactly as your doctor has told you. You should check with your doctor if you are not sure.

The dose of Keral that you need depends on the type, severity and duration of your pain. Your doctor will tell you how many tablets you must take daily, and for how long.

The recommended dosage is generally 1 tablet (25 mg) every 8 hours, with no more than 3 tablets daily (75 mg).

If you are elderly, or if you suffer from kidney or liver problems, you should start treatment with a total daily dose of no more than 2 tablets (50 mg).

In elderly patients this initial dose can later be increased to that generally recommended (75 mg) if Keral has been well tolerated.

If your pain is intense and you need quicker relief, take the tablets on an empty stomach (at least 30 minutes before food) because they will be more easily absorbed (see section 2 “Taking Keral with food and drink”).
