The lowest possible dose and the shortest possible treatment time should always be sought to reduce the risk of side effects. In general, higher doses than recommended can lead to risks. This also means that the combination of several NSAIDs at the same dose should be avoided.

  • inflammatory bowel diseases (such as ulcerative colitis, Crohn’s disease )
  • SLE (connective tissue disease)
  • high blood pressure
  • heart failure
  • kidney or liver disease

Elderly people should be aware of the increased risk of side effects that exist in old age.

Especially at the beginning of treatment, patients who have previously had problems with the gastrointestinal tract, especially elderly patients, should contact a doctor in case of abdominal symptoms.

Medicines such as Alganex may have a small increased risk of heart attack or stroke. Such an increase in risk is more likely with the use of high doses and with long-term treatment. Do not exceed the recommended dose or treatment time.
