Below are the undesirable phenomena (AEs) that were identified during clinical trials, as well as the use of diclofenac in clinical practice.
The following criteria were used to estimate the frequency of AE: "often" - ≥ 1/100, <1/10, "infrequently" - 1/1000, <1/100, "rarely" - ≥ 1/10000, <1/1000, "very rarely" - <1/10000, including individual cases. AEs are grouped according to the system-organ class of the medical dictionary for regulatory activities MedDRA, within each class of HH are listed in order of decreasing frequency of occurrence, within the limits of each group allocated according to the frequency of occurrence, AEs are distributed in order of decreasing importance.
Violations of the blood and lymphatic system: very rarely - thrombocytopenia, leukopenia, hemolytic anemia, aplastic anemia, agranulocytosis.
Immune system disorders: rarely - hypersensitivity, anaphylactic / anaphylactoid reactions, including lowering blood pressure (BP) and shock; very rarely - angioedema (including face swelling).
Disorders of the psyche: rarely disorientation, depression, insomnia, nightmares, irritability, mental disorders.
Disturbances from the nervous system: often - headache, dizziness; rarely - drowsiness; very rarely - paresthesia, memory disorders, convulsions, anxiety, tremor, aseptic meningitis, taste disorders, acute disorders of cerebral circulation.
Disturbances on the part of the organ of sight: very rarely - visual impairment (blurred vision, diplopia).
Hearing disorders and labyrinthine disorders: often - vertigo; very rarely - noise in the ears, hearing loss.
Heart Disease: infrequently - myocardial infarction, heart failure, palpitation, chest pain.
Vascular disorders: very rarely - increased blood pressure, vasculitis.
Disturbances from the respiratory system, chest and mediastinal organs: rarely - bronchospasm; very rarely - pneumonitis.
Disorders from the gastrointestinal tract: often - nausea, vomiting, diarrhea, dyspepsia, abdominal pain, flatulence, decreased appetite; rarely - gastritis, gastrointestinal bleeding, vomiting of blood, diarrhea with an admixture of blood, melena, stomach and intestinal ulcers (with or without bleeding, stenosis or perforation, with possible development of peritonitis); very rarely - colitis (nonspecific hemorrhagic colitis, ischemic colitis, exacerbation of ulcerative colitis or Crohn's disease), constipation, stomatitis, glossitis, damage to the esophagus, the appearance of diaphragm-like strictures in the intestine, pancreatitis, dysgeusia.
Disturbances from the liver and bile ducts: often - increased activity of "liver" transaminases; rarely - hepatitis, jaundice, liver dysfunction; very rarely - fulminant hepatitis, liver necrosis, liver failure.
Disturbances from the skin and subcutaneous tissues: often - skin rash; rarely - hives; very rarely - bullous dermatitis, eczema, erythema, erythema multiforme, Stevens-Johnson syndrome, Lyell's syndrome (toxic epidermal necrolysis), exfoliative dermatitis, alopecia, photosensitivity reactions, purpura Shenlen-Henoch, itchy skin.
Disorders from the kidneys and urinary tract: very rarely - acute kidney damage (acute renal failure), hematuria, proteinuria, nephrotic syndrome,
Tubulointerstitial nephritis, papillary necrosis.
General disorders and disorders in place introduction of: rarely - swelling.
Disorders from the cardiovascular system
Clinical studies indicate a slight increase in the risk of developing cardiovascular thrombotic complications (eg, myocardial infarction), especially with prolonged use of diclofenac or with high doses (daily dose of more than 150 mg).
Visual disorders
Visual disorders such as visual impairment, blurred vision, or diplopia appear to be class effects of NSAIDs, and are reversible after discontinuation. A possible mechanism for the development of such disorders is the inhibition of the synthesis of prostaglandins and other related substances, which changes the regulation of blood flow in the retina, which is manifested by potential visual disorders. If such symptoms develop with diclofenac therapy, consider ophthalmic examination to exclude any other reasons.
If any of the side effects listed in the manual are aggravated, or if you notice any other side effects not listed in the instructions, inform the doctor about it.
