Precautions for use

Carefully and under the supervision of a physician, the drug should be used in patients with impaired liver or kidney function, with a tendency to hypotension, bronchial asthma, increased individual sensitivity to nonsteroidal anti-inflammatory drugs or non-narcotic analgesics, a complete or incomplete combination of asthma, recurrent nasal polyposis and okolonosovyh sinuses and intolerance Acetylsalicylic acid or other non-steroidal anti-inflammatory drugs (including a history).

For children and adolescents under 18 years old, the drug should be used only as prescribed by a doctor.


Symptoms: vomiting, lowering blood pressure, drowsiness, confusion, nausea, epigastric pain, abnormal liver and kidney function, convulsions.

Treatment: symptomatic therapy.

Adverse Effects

At therapeutic doses, the drug is usually well tolerated. Sometimes allergic reactions (skin rash, itching, very rarely - anaphylactic shock, urticaria), angioedema are possible. In rare cases - a burning sensation in the epigastric region, dry mouth, headache.

Perhaps dizziness, lowering blood pressure, tachycardia, cyanosis. With prolonged use, hematopoietic disorders: thrombocytopenia, leukopenia, agranulocytosis (may include the following symptoms: unmotivated rise in temperature, chills, sore throat, difficulty swallowing, stomatitis, and the development of symptoms of vaginitis or proctitis). With a tendency to bronchospasm may provoke an attack.

Very rarely, malignant exudative erythema (Stevens-Johnson syndrome), toxic epidermal necrolysis (Lyell's syndrome).

Rarely (usually with long-term use or the appointment of high doses) - renal dysfunction: oliguria, anuria, proteinuria, interstitial nephritis, urine staining in red. Very rarely - a decrease in sweating, accommodation paresis, difficulty urinating.

Local reactions: intramuscular injection may cause infiltrates at the injection site.

All side effects should be reported to your doctor.

Interaction with other drugs

The simultaneous use of spazgan with other non-narcotic analgesics can lead to mutual enhancement of toxic effects.Tricyclic antidepressants, oral contraceptives, Allopurinol violate the metabolism of metamizole sodium in the liver and increase its toxicity.

Barbiturates, phenylbutazone and other inducers of microsomal liver enzymes weaken the effect of metamizole sodium.

Simultaneous use with cyclosporine reduces the level of the latter in the blood.

Sedatives and tranquilizers enhance the analgesic effect of metamizole sodium.

When applied simultaneously with H- histamine blockers, butyrophenones, phenothiazines, amantadine and quinidine may enhance the M-cholinolytic action.

When applied simultaneously with ethanol - mutual enhancement of effects.

Simultaneous use with chlorpropromazine or other phenothiazine derivatives may lead to the development of severe hyperthermia.

Radiocontrast drugs and colloidal blood substitutes should not be used during treatment with drugs containing metamizole sodium.

Metamizole sodium, displacing oral hypoglycemic drugs, indirect anticoagulants, glucocorticosteroids and Indomethacin from the association with plasma proteins , may increase the severity of their action.

Tiamazol and cytostatics increase the risk of leukopenia.

The effect of enhancing codeine, H- histamine blockers and propranolol (slows down the inactivation of metamizole sodium).

The injection solution is pharmaceutically incompatible with other drugs.

If necessary, the simultaneous use of these and other drugs should consult with your doctor.
