Gastrointestinal tract (GIT): NSAIDs-gastropathy (abdominal pain, nausea, vomiting, heartburn, decreased appetite, diarrhea, flatulence, constipation, ulceration of the gastrointestinal mucosa, which in some cases is complicated by perforation and bleeding); irritation or dryness of the oral mucosa, pain in the mouth, ulceration of the gingival mucosa, aphthous stomatitis, pancreatitis.
Hepatobiliary system: hepatitis.
Respiratory system: shortness of breath, bronchospasm. The organ of hearing: hearing loss, ringing or noise in the ears.
Central and peripheral nervous system: headache, dizziness, insomnia, anxiety, nervousness and irritability, psychomotor agitation, drowsiness, depression, confusion, hallucinations, aseptic meningitis (more often in patients with autoimmune diseases).
The cardiovascular system: heart failure, tachycardia, increased blood pressure.
Urinary system: acute renal failure, allergic nephritis, nephrotic syndrome (edema), polyuria, cystitis.
Allergic reactions: skin rash (usually erythematous or urticaria), itchy skin, Quincke's edema, anaphylactoid reactions, anaphylactic shock, bronchospasm or dyspnea, fever, erythema multiforme exudative (including Stevens-Johnson syndrome), toxic epidermal necrolysis (Lyell's syndrome), eosinophilia, allergic rhinitis.
Hematopoiesis: anemia (including haemolytic, aplastic), thrombocytopenia and thrombocytopenic purpura, agranulocytosis, leukopenia.
Body of vision: toxic optic nerve damage, blurred vision or dying, scotoma, dry and irritated eyes, conjunctival edema and eyelids (allergic genesis).
The risk of ulceration of the gastrointestinal mucosa, bleeding (gastrointestinal, gingival, uterine, hemorrhoidal), visual impairment (color vision, scotoma, optic nerve damage) increases with prolonged use of the drug in large doses.
Laboratory indicators:
- bleeding time (may increase);
- serum glucose concentration (may decrease);
- clearance of creatinine (may decrease);
- hematocrit or hemoglobin (may decrease);
- serum creatinine concentration (may increase);
- activity of "liver" transaminases (may increase).
