Below are the undesirable phenomena that have been identified in clinical trials, as well as the use of diclofenac in clinical practice.
To assess the incidence of adverse events, the following criteria are used: "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). For each system of organs, undesirable phenomena are grouped in order of decreasing frequency of their occurrence. Within each group allocated according to frequency of occurrence, undesirable phenomena are distributed in order of decreasing importance.
Infectious and parasitic diseases: very rarely - post-injection abscess.
Violations from the blood and lymphatic system: very rarely - thrombocytopenia, leukopenia, hemolytic anemia, aplastic anemia, agranulocytosis.

Vascular disorders: highly rarely - increased blood pressure, vasculitis.
Disorders from the respiratory system, chest mediastinum: rarely - bronchial asthma (including dyspnea); very rarely - pneumonitis.
Disturbances 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 or perforation); very rarely - stomatitis, glossitis, damage to the esophagus, the appearance of diaphragm-like strictures in the intestine, colitis (nonspecific hemorrhagic 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; impaired liver function; 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 syndrome (toxic epidermal necrolysis), exfoliative dermatitis, pruritus, alopecia, photosensitivity reactions; purple, purple Shenlaine-Henoch.
Disorders from the kidneys and urinary tract: very rarely - acute renal failure, hematuria, proteinuria, tubulo-interstitial nephritis, nephrotic syndrome, papillary necrosis.
General disorders and disorders at the site of administration: often - pain, compaction at the injection site; rarely - swelling, necrosis at the injection site.
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).
If any of the side effects indicated in the manual are aggravated, or you notice any other side effects not indicated at instructions, inform the doctor about it.
