ByAccording to the World Health Organization (WHO), adverse events are classified according to their developmental frequency 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), the frequency is unknown (it is not possible to determine the frequency of occurrence according to available data).
Infectious and parasitic diseases: infrequently - fungal superinfections; rarely - pseudomembranous colitis (in very rare cases with possible fatal outcome).
Violations of the blood and lymphatic system: infrequently - eosinophilia; rarely anemia, neutropenia, thrombocytopenia, leukocytosis, thrombocythemia, leukopenia; very rarely - hemolytic anemia, pancytopenia (life threatening), agranulocytosis, oppression of bone marrow hematopoiesis (life threatening).
Immune system disorders: rarely - allergic reactions, allergic edema / angioedema; very rarely - anaphylactic reactions, anaphylactic shock (life threatening), serum sickness.
Disorders from the metabolism and nutrition: infrequently - anorexia, decreased appetite and intake of food; rarely - hyperglycemia, hypoglycemia.
Disorders of the psyche: infrequently - psychomotor hyperactivity / agitation; rarely confusion and disorientation, anxiety, depression (which can lead to self-damaging behavior, such as suicidal behavior / thoughts, as well as suicide attempt or suicide), nightmares, hallucinations; very rarely - psychotic reactions (which can lead to self-damaging behavior, such as suicidal behavior / thoughts, as well as attempted suicide or suicide).
Disturbances from the nervous system: infrequently - dizziness, headache, sleep disturbance, taste disorder; rarely - tremor, convulsions (including epileptic seizures), vertigo, hypoesthesia, paresthesia and dysesthesia; very rarely - migraine, impaired coordination of movements, impaired sense of smell, gait disorders, benign intracranial hypertension, hyperesthesia; frequency is unknown - peripheral neuropathy and polyneuropathy.
Disturbances on the part of the organ of sight: rarely - visual disturbances; very rarely - a violation of color perception.
Hearing disorders and labyrinthine disorders: rarely - tinnitus, hearing loss / hearing loss.
Heart Disease: rarely - tachycardia; frequency unknown - ventricular arrhythmias (including the "pirouette" type), predominantly in patients with risk factors for prolonging the QT interval, prolongation of the QT interval.
Vascular disorders: rarely - vasodilation, lowering blood pressure, fainting, feeling of "tide" of blood to the face; very rarely - vasculitis.
Disturbances from the respiratory system, chest and mediastinal organs: rarely - violation of breathing (including bronchospasm).
Disorders from the gastrointestinal tract: often - nausea, diarrhea; infrequently - dyspepsia, vomiting, pain in the abdomen, flatulence; very rarely - pancreatitis.
Disturbances from the liver and bile ducts: infrequently - increased activity of "liver" transaminases, increased bilirubin concentration; rarely - violations of the liver, cholestatic jaundice, hepatitis; very rarely - necrosis of liver tissue (in extremely rare cases progressing to life-threatening liver failure).
Disturbances from the skin and subcutaneous tissues: infrequently - itching, rash, hives; rarely photosensitivity reactions,formation of blisters of unspecified etiology; very rarely - petechia, erythema multiforme, erythema nodosum, Stevens-Johnson syndrome (potentially life-threatening), toxic epidermal necrolysis (Lyell syndrome) (potentially life-threatening); frequency unknown - acute generalized pustular exanthema.
Disturbances from musculoskeletal and connective tissue: infrequently - arthralgia, musculoskeletal pain (including pain in the extremities, back pain, chest pain); rarely - myalgia, arthritis, increased muscle tone, muscle cramps; very rarely - muscle weakness, tendonitis, rupture of tendons (mainly Achilles), exacerbation of myasthenia gravis symptoms.
Disorders from the kidneys and urinary tract: infrequently - impaired renal function; rarely - renal failure, hematuria, crystalluria, tubulointerstitial nephritis.
General disorders and disorders at the site of administration: often - reactions at the injection site (pain, burning, redness, phlebitis); infrequently - general weakness, fever; rarely - swelling, increased sweating.
Laboratory and instrumental data: infrequently - increased activity of alkaline phosphatase in the blood; rarely - changes in the concentration of prothrombin (including hypoprothrombinemia), increased activity of amylase; frequency unknown - an increase in the international normalized ratio (INR) (in patients taking vitamin K antagonists).
The frequency of development of the following side effects with intravenous administration and with the use of stepwise therapy of ciprofloxacin (with intravenous administration of the drug with subsequent ingestion) is higher than with oral administration:
Often: vomiting, transient increase in the activity of "liver" transaminases, rash.
Infrequently: thrombocytopenia, thrombocythemia, confusion and disorientation, hallucinations, paresthesia and dysesthesia, convulsions, vertigo, visual impairment, hearing loss, tachycardia, vasodilation, lowering of blood pressure, reversible liver function abnormalities, cholestatic jaundice, kidney failure, edema.
Rarely: pancytopenia, bone marrow suppression, anaphylactic shock, psychotic reactions, migraine, olfactory impairment, hearing impairment, vasculitis, pancreatitis, liver tissue necrosis, petechiae, tendon rupture.
Children: children more often than adults reported on the development of arthropathies.
