Radiocontrast agents, colloidal blood substitutes and penicillin should not used during treatment with drugs containing metamizol sodium.
With the simultaneous use of metamizole sodium with cyclosporine decreases the concen- tration of the latter in the blood.
Metamizole sodium, displacing from the connection with plasma proteins, oral hypoglycemic medicines, indirect anticoagulants, glucocorticosteroids and indomethacin increases their effect.
Phenylbutazone, barbiturate and other inducers of microsomal liver enzymes at simultaneous use reduce the effectiveness of metamizole sodium.
Simultaneous use with non-narcotic analgesics, tricyclics antidepressants, hormonal contraceptives and allopurinol may cause to increase the toxicity of metamizole sodium.
Sedation and anxiolytic drugs (tranquilizers) enhance analgesic effect of metamizole sodium.
Thiamazole and cytostatics increase the risk of developing leukopenia against the background of preparations containing metamizol sodium.
The effect of sodium metamizole increases codeine, H2-histamine receptor blockers and propranolol (slows metabolism).
Myelotoxic drugs increase manifestations of hematotoxicity metamizole sodium.
Derivatives of butyrophenone, phenothiazine, tricyclic antidepressants, blockers H2-gistaminovyh receptors, amantadine and quinidine strengthen m-holinoblocking action fenpiverinia bromide.
With simultaneous application fenpiveriniya bromide minutes phenothiazine derivatives (e.g., chlorpromazine) developing severe hyperthermia may occur.
Metamizole sodium enhances the effect of ethanol.
