Frequency occurrence undesirable reactions / adverse events (HP / AE) was obtained from literature and clinical studies.If the frequency of occurrence for the same HP / A in the literature and data from clinical trials varied, the highest incidence of HP / AH was indicated. The following gradations of the frequency of occurrence of HP / AH by classification CIOMS (Council of People's Medical Scientific Organizations): very often> 10 %; often> 1 % and < 10%; infrequently> 0.1% and < 1 %; rarely> 0.01% and <0.1 %; rarely < 0,01 %, frequency unknown (it is not possible to determine the frequency of occurrence of HP / AH from the available data).
Disorders from the metabolism and nutrition
Often
- Violations of the water-electrolyte balance, including those occurring with clinical symptoms. Symptoms that indicate the development of violations of water electrolyte balance may include headache, convulsions, tetany, muscle weakness, heart rhythm disturbances and dyspeptic disorders. These disorders can develop either gradually (for a long time) or quickly (for a very short time, for example, in the case of high doses of furosemide in patients with normal renal function). The factors,contributing to the development of violations vodnoehlektrolitnogo balance, are the main diseases (for example, cirrhosis of the liver or heart failure); concomitant therapy with means that change the water-electrolyte balance; malnutrition and drinking regimen; vomiting, diarrhea, profuse sweating.
- Dehydration and hypovolemia (decrease in the volume of circulating blood), especially in elderly patients, which can lead to hemoconcentration with a tendency to develop thrombosis (see subsection "Vascular disorders" below).
- Increase in the concentration of creatinine in the blood.
- Increase in the concentration of triglycerides in the blood.
Often
- Hyponatremia, hypochloraemia, hypokalemia, increased cholesterol concentration in the blood, increased concentration of uric acid in the blood and development of an attack of gout.
Infrequently
- Decreased glucose tolerance. Possible manifestation of latent diabetes mellitus (see section "Special instructions").
Frequency unknown
- Hypocalcemia, hypomagnesemia, increased concentration and urea in the blood, metabolic alkalosis, Barter's pseudosyndrome with incorrect and / or prolonged use of furosemide.
Vascular disorders
Often (for intravenous infusion)
- Reduction of blood pressure (BP), including orthostatic hypotension.
Rarely
- Vasculitis.
Frequency unknown
- Thrombosis.
Disorders from the nochek and urinary tract
Often
- Increase the volume of urine.
Rarely
- Tubulointerstitial nephritis.
Frequency unknown
- Increase in the content of sodium and chloride in the urine; urinary retention (in patients with partial obstruction of the urinary tract, see section "Special instructions");
nephrocalcinosis / nephrolithiasis in premature infants (see section "Special instructions"), renal failure (see section "Interaction with other drugs"). Disorders from the digestive system
Infrequently
- Nausea.
Rarely
- Vomiting, diarrhea.
Rarely
- Acute pancreatitis.
Disturbances from the liver and bile ducts
Rarely
- Cholestasis, an increase in the activity of "liver" transaminases. Disturbances from the nervous system
Often
- Hepatic encephalopathy in patients with hepatocellular insufficiency (see the section "Contraindications").
Rarely
- Paresthesia.
Hearing disorders and labyrinthine disorders
Infrequently
- Hearing disorders, usually transient, especially in patients with renal insufficiency, hypoproteinemia (eg, with nephrotic syndrome) and / or too fast intravenous administration of furosemide. There have been reported cases of deafness, sometimes irreversible, after taking furosemide by mouth or intravenously.
Rarely
- Noise in ears.
Disturbances from the skin and subcutaneous tissues
Infrequently
- Skin itching, hives, rashes, bullous dermatitis, erythema multiforme, pemphigoid, exfoliative dermatitis, purpura, photosensitization reactions.
Frequency unknown
- Stevens-Johnson syndrome, toxic epidermal necrolysis, acute generalized exanthematous pustulosis, DRESS-siydrome: drug rash with eosinophilia and systemic symptoms.
Immune system disorders
Rarely
- Severe anaphylactic or anaphylactoid reactions until the development of anaphylactic shock.
Frequency unknown
- Weighting of the flow or exacerbation of systemic lupus erythematosus.
Violations of the blood and lymphatic system
Often
- Haemoconcentration.
Infrequently
- Thrombocytopenia.
Rarely
- Leukopenia, eosinophilia.
Rarely
- Agranulocytosis, aplastic anemia or hemolytic anemia.
Congenital, hereditary and genetic disorders
Frequency unknown
- Increased risk of non-invasion of the arterial duct, when furosemide is introduced to premature infants during the first weeks of life.
General disorders and disorders at the site of administration
Rarely
- Fever.
Frequency unknown
- After intramuscular injection, a local reaction in the form of pain is possible.
Since some adverse reactions (such as a change in the blood picture, severe anaphylactic or anaphylactoid reactions, severe skin allergic reactions) may, under certain conditions, threaten the life of patients, then any side effects should immediately be reported to the doctor.
