| Gastro-intestinal: the most commonly-observed adverse events are gastro-intestinal in nature. Nausea, vomiting, diarrhoea, dyspepsia, abdominal pain, melaena, haematemesis, ulcerative stomatitis and gastro-intestinal haemorrhage have been reported following administration. Less frequently, gastritis, duodenal ulcer, gastric ulcer and gastro-intestinal perforation have been observed.Hypersensitivity: Hypersensitivity reactions have been reported following treatment with NSAIDs. These may consist of (a) non-specific allergic reaction and anaphylaxis, (b) respiratory tract reactivity comprising of asthma, aggravated asthma, bronchospasm or dyspnoea, or (c) assorted skin disorders, including rashes of various types, pruritus, urticaria, purpura, angiodema and, less commonly, bullous dermatoses (including epidermal necrolysis, erythema multiforme and exfoliative dermatitis).Cardiovascular: Oedema, hypertension, and cardiac failure, have been reported in association with NSAID treatment. Clinical trial and epidemiological data suggest that use of ibuprofen, particularly at high dose (2400 mg daily), and in long term treatment may be associated with a small increased risk of arterial thrombotic events (for example myocardial infarction or stroke) (see section 4.4).Other adverse events reported less commonly include:Hepatic: abnormal liver function, hepatitis and jaundice.Neurological and special senses: Visual disturbances, optic neuritis, headaches, paraesthesia, depression, confusion, hallucinations, tinnitus, vertigo, dizziness, malaise, fatigue and drowsiness.Haematological: thrombocytopenia, neutropenia, agranulocytosis, aplastic anaemia and haemolytic anaemia.Renal: Nephrotoxicity in various forms, including intestinal nephritis, nephrotic syndrome and renal failure.Dermatological: photosensitivity.
