Below are the undesirable phenomena (AEs) that were identified in the course of clinical studies, as well as the use of diclofenac in clinical practice.
To assess the frequency of AE, the following criteria are used: "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 the regulatory activities of MedDRA,Within each class, the AHs are listed in descending order of frequency, within each group allocated according to the frequency of occurrence, the AEs are distributed in order of decreasing importance.
Violations from 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: very rarely disorientation, depression, insomnia, nightmares, irritability, mental disorders.
Disturbances from the nervous system: often - headache, dizziness; rarely - drowsiness; very rarely, sensitivity disorders, including paresthesia, memory disorders, tremors, convulsions, anxiety, acute disorders of cerebral circulation, aseptic meningitis.
Disorders from the side of the organ of vision: very rarely - visual impairment (blurred vision), diplopia.
Hearing disorders and labyrinthine disturbances: often - vertigo; very rarely - hearing impairment, tinnitus.
Heart Disease: infrequently - myocardial infarction, heart failure, palpitation, chest pain.
Vascular disorders: very rarely - increased blood pressure, vasculitis.
Disturbances from the respiratory system, chest organs of the mediastinum: rarely - bronchial asthma (including dyspnea); very rarely - pneumonitis.
Disorders from the gastrointestinal tract: often - abdominal pain, nausea, vomiting, diarrhea, dyspepsia, flatulence, decreased appetite; rarely - gastritis, gastrointestinal bleeding, vomiting of blood, melena, diarrhea with blood, ulcers of the stomach and intestines (with or without bleeding, stenosis or perforation, with possible development of peritonitis); very rarely - stomatitis, glossitis, damage to the esophagus, the appearance of diaphragm-like strictures in the intestine, colitis (nonspecific hemorrhagic colitis, ischemic colitis, exacerbation of ulcerative colitis or Crohn's disease), constipation, pancreatitis, dysgeusia.
Disorders from the liver and bile ducts: often increased activity of aminotransferases in blood plasma; 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, pruritus, alopecia, photosensitivity reactions, purpura, purpura Shenlaine-Genocha.
Disorders from the kidneys and urinary tract: very rarely - acute kidney damage (acute renal failure), hematuria, proteinuria, tubulo-interstitial nephritis, nephrotic syndrome, papillary necrosis.
General disorders and disorders at the site of administration: 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 in 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. With the development of such symptoms with diclofenac therapy should consider the possibility of 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, tell your doctor.
