|Hypersensitivity reactions have been reported and these may consist of:(a) Non-specific allergic reactions and anaphylaxis(b) Respiratory tract reactivity, eg asthma, aggravated asthma, bronchospasm, dyspnoea(c) Various skin reactions, e.g. pruritus, urticaria, angioedema and more rarely exfoliative and bullous dermatoses (including epidermal necrolysis and erythema multiforme) The following list of adverse effects relates to those experienced with ibuprofen at OTC doses, for short-term use. In the treatment of chronic conditions, under long-term treatment, additional adverse effects may occur.|
Hypersensitivity reactions:Uncommon: Hypersensitivity reactions with urticaria and pruritus.Very rare: severe hypersensitivity reactions. Symptoms could be: facial, tongue and laryngeal swelling, dyspnoea, tachycardia, hypotension, (anaphylaxis, angioedema or severe shock).Exacerbation of asthma and bronchospasm.
Gastrointestinal:The most commonly observed adverse events are gastrointestinal in nature.Uncommon: abdominal pain, nausea, dyspepsiaRare: diarrhoea, flatulence, constipation and vomiting.Very rare: peptic ulcer, perforation or gastrointestinal haemorrhage, melaena, haematemesis, sometimes fatal, particularly in the elderly. Ulcerative stomatitis, gastritis.Exacerbation of colitis and Crohn's disease (see section 4.4).
Nervous System: Uncommon: HeadacheVery rare: Aseptic meningitis single cases have been reported very rarely.
Renal: Very rare: Acute renal failure, papillary necrosis, especially in long-term use, associated with increased serum urea and oedema.
Hepatic:Very rare: liver disorders.
Haematological: Very rare: Haematopoietic disorders (anaemia, leucopenia, thrombocytopenia, pancytopenia, agranulocytosis). First signs are: fever, sore throat, superficial mouth ulcers, flu-like symptoms, severe exhaustion, unexplained bleeding and bruising.
Skin:Uncommon: Various skin rashesVery rare: Severe forms of skin reactions such as bullous reactions including Stevens-Johnson syndrome, erythema multiforme and toxic epidermal necrolysis can occur
Immune System:In patients with existing auto-immune disorders (such as systemic lupus erythematosus, mixed connective tissue disease) during treatment with ibuprofen, single cases of symptoms of aseptic meningitis, such as stiff neck, headache, nausea, vomiting, fever or disorientation have been observed (See section 4.4)
Cardiovascular and CerebrovascularOedema, 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 doses 2400mg 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).
