According to the World Health Organization (WHO), adverse reactions are classified according to their frequency of development as follows: very often (≥ 1/10); often (≥ 1/100, <1/10); infrequently (≥ 1/1000, <1/100); rarely (≥ 1/10000, <1/1000); very rarely (<1/10000), including individual messages; frequency (frequency can not be calculated from available data).
From the central nervous system: often - a disorder of taste, sleep disorders, dizziness, drowsiness; rarely - headache, paresthesia, asthenia; very rarely - depression, cerebrovascular disorders, including stroke, syncope, impaired consciousness.
From the skin: often - skin itching with rashes and without rashes, skin rash (maculopapular, less often - vesicular or bullous nature), baldness; very rarely - hives, Stevens-Johnson syndrome, erythema multiforme, photosensitivity, erythroderma, exfoliative dermatitis, pemphigoid reactions.
From the genitourinary system: rarely - renal failure, acute renal failure, polyuria, oliguria, increased frequency of urination; very rarely - nephrotic syndrome, sexual dysfunction, gynecomastia.
From the side of metabolism: rarely anorexia; very rarely - hyperkalemia, hypoglycemia.
From the musculoskeletal system: very rarely - myalgia, arthralgia.
From the digestive system: often - dryness of the oral mucosa, nausea, vomiting, abdominal pain, diarrhea, constipation; rarely - stomatitis, aphthous ulcers internal mucosal surfaces of the cheeks and tongue, gingival hyperplasia; very rarely - glossitis, peptic ulcer, pancreatitis, impaired liver function, cholestasis, jaundice, hepatitis (including rare cases of gepatonekroz), increased activity of "liver" transaminases, increased bilirubin concentration in blood serum, angioneurotic edema of the intestinal mucosa.
From the hematopoiesis: very rarely - neutropenia, agranulocytosis, pancytopenia, especially in patients with renal dysfunction, anemia (including aplastic, hemolytic), anemia, lymphadenopathy, eosinophilia, autoimmune disease and / or increase in titer antinuclear antibody.
From the respiratory system: often - dry, irritating (unproductive) cough, shortness of breath; very rarely - bronchospasm, rhinitis, allergic alveolitis, eosinophilic pneumonia, pulmonary edema.
From the sense organs: very rarely - a violation of visual acuity.
From the cardiovascular system: infrequently - tachycardia or tachyarrhythmia, palpitations, angina pectoris, orthostatic hypotension, Raynaud's syndrome, "flushes" of blood to the face, pallor, peripheral edema; very rarely - cardiogenic shock, cardiac arrest.
Laboratory indicators: very rarely - proteinuria, eosinophilia, hyperkalemia, hyponatremia, hypoglycemia, increased urea nitrogen and creatinine in the blood plasma, acidosis, hemoglobin and hematocrit decrease, decrease in the number of leukocytes, platelets, increased erythrocyte sedimentation rate (ESR).
Other: infrequently - pain in the chest, increased fatigue, weakness; very rarely - fever; the frequency is unknown - the symptom complex, which includes flushing of the facial skin, nausea, vomiting and lowering of blood pressure.
