Clinical studies suggest that the use of ibuprofen, particularly at high doses (2400 mg daily) is likely to be associated with a slightly increased risk of arterial thrombotic events (myocardial infarction or stroke, for example) (see Precautions).
The most frequently observed side effects are of a gastrointestinal nature. Peptic ulcers, perforations or gastrointestinal bleeding, sometimes fatal, may occur, particularly in the elderly (see Precautions).
Nausea, vomiting, diarrhoea, flatulence, constipation, dyspepsia, ulcerative stomatitis, abdominal pain, melaena, haematemesis, exacerbation of rectocolitis or Crohn's disease (see Precautions) have been reported following administration of NSAIDs. Less frequently, gastritis has been observed.
Edema, hypertension and heart failure have been reported in association with NSAID therapy.
The table as follows lists adverse reactions by system organ class and frequency (very common ≥1/10, common [≥1/100, <1/10], uncommon [≥1/1,000, <1/100], rare [≥1/10,000, <1/1,000], very rare [<1/10,000] and not known [cannot be estimated from the available data]). (See table.)

Pediatric population: Based on accumulated clinical experience, no clinically meaningful differences in the safety profile have been observed between adults and the approved pediatric population E 12 years of age) in terms of the nature, frequency, severity and reversibility of effects unwanted.
