The drug can affect the psychomotor ability of the patient with simultaneous reception with alcohol and drugs that depress the central nervous system, in view of increased sedative activity of alcohol-containing drugs. The simultaneous use of Renalgan ® with non-narcotic analgesics can lead to a mutual enhancement of toxic effects. Toxic effects of metamizole sodium are enhanced by the simultaneous administration of tricyclic antidepressants, oral contraceptives, allopurinol. Antagonists of histamine H2-receptors, barbiturates, codeine with simultaneous use enhance the effect of metamizole sodium.
When co-administered with S-histamin blockers, butyrophenones, phenothiazines, tricyclic antidepressants, amantadine and quinidine, m-choline blocking effect may be enhanced.
Simultaneous use with chlorpromazine or other derivatives of phenothiazine may lead to the development of severe hyperthermia.
Phenylbutazone and others.hepatoinducers at the same time reduce the effectiveness of metamizole sodium.
Sedative and anxiolytic drugs (drugs) (tranquilizers) increase the analgesic effect of metamizole sodium.
Radiocontrast drugs, colloidal blood substitutes and penicillin should not be used during treatment with drugs containing metamizol sodium.
With the simultaneous administration of cyclosporine, the concentration of the latter in the blood decreases.
Metamizole sodium, displacing from the connection with the protein, oral hypoglycemic drugs, indirect anticoagulants, glucocorticoid agents and indomethacin, can increase the severity of their action.
Thiamazole and cytostatics increase the risk of developing leukopenia.
