The risk of side effects can be minimized if you take the drug with a short course, at the lowest effective dose needed to eliminate the symptoms.
Side effects are predominantly dose-dependent.
The following adverse reactions were noted with a short-term intake of ibuprofen in doses not exceeding 1200 mg / day. In the treatment of chronic conditions and with prolonged use, other side reactions may occur.
The incidence of side effects is classified according to the recommendations of the World Health Organization: very often (> 1/10), often (> 1/100, <1/10), infrequently (> 1/1000, <1/100), rarely > 1/10 000, <1/1000), very rarely (<1/10 000, including individual messages); frequency is unknown - there is no data on frequency estimation.
Violations of the blood and lymphatic system: very rarely - hemopoiesis disorders (anemia, leukopenia, aplastic anemia, hemolytic anemia, thrombocytopenia, pancytopenia, agranulocytosis). The first symptoms of such disorders are fever, sore throat, superficial oral ulcers, flu-like symptoms, severe weakness, nosebleeds and bruising, bleeding, and bruising of unknown etiology.
Immune system disorders: infrequently - hypersensitivity reactions - nonspecific allergic reactions and anaphylactic reactions, respiratory tract reactions (bronchial asthma, including its aggravation, bronchospasm, dyspnea, dyspnea), skin reactions (itching, urticaria, purpura, Quincke's edema, exfoliative and bullous dermatoses, including toxic epidermal necrolysis, Stevens-Johnson syndrome, erythema multiforme), allergic rhinitis, eosinophilia; very rarely severe hypersensitivity reactions, including swelling of the face, tongue and larynx, dyspnea, tachycardia, arterial hypotension (anaphylaxis, Quincke's edema or severe anaphylactic shock).
Disorders from the gastrointestinal tract: infrequently - pain in the abdomen, nausea, dyspepsia; rarely - diarrhea, flatulence, constipation, vomiting; very rarely - peptic ulcer, perforation or gastrointestinal bleeding, melena, bloody vomiting, ulcerative stomatitis, gastritis; frequency unknown - exacerbation of ulcerative colitis and Crohn's disease.
Disorders from the urinary system and liver: very rarely - acute renal failure, especially,with prolonged use, in combination with an increase in the level of urea in the blood plasma and the appearance of edema, papillary necrosis, impaired liver function, hepatitis.
Disturbances from the nervous system: infrequently - a headache; very rarely - aseptic meningitis (in patients with autoimmune diseases).
Disorders from the cardiovascular system: frequency unknown - heart failure, peripheral edema, with prolonged use increased risk of thrombotic complications (eg, myocardial infarction, stroke), increased blood pressure.
Disturbances from the respiratory system and mediastinal organs: the frequency is unknown - bronchial asthma, bronchospasm, dyspnea.
Other: very rarely - edema, including peripheral.
Laboratory indicators: hematocrit or hemoglobin (may decrease); bleeding time (may increase); the concentration of glucose in the blood plasma (may decrease); clearance of creatinine (may decrease); plasma concentration of creatinine (may increase); activity of "liver" transaminases (may increase).
If side effects occur, stop taking the medication and consult a doctor.
