Simultaneous use of Spasmalgon with other non-narcotic analgesics may lead to mutual enhancement of toxic effects.
Sedatives and tranquilizers increase the analgesic effect of metamizole sodium.
Tricyclic antidepressants, oral contraceptives, allopurinol disrupt the metabolism of metamizole sodium in the liver and increase its toxicity.
Barbiturates, phenylbutazone and other inducers of microsomal liver enzymes weaken the action of metamizole sodium.
Radiopaque drugs, colloidal blood substitutes and penicillin should not be used during treatment with drugs containing metamizol sodium. Simultaneous use with cyclosporine reduces the concentration of the latter in the blood. Metamizol sodium, displacing from the connection with plasma proteins, oral hypoglycemic drugs, indirect anticoagulants, glucocorticoids and indomethacin, can increase the severity of their action.
When combined with blockers Hi-gistaminovyh receptors, butirofenonami, phenothiazines, tricyclic antidepressants, amantadine and quinidine may increase m-hol and non-blocking effect.
Enhances the effects of ethanol.
Simultaneous use with chlorpromazine or other derivatives of phenothiazine may lead to the development of severe hyperthermia.
Thiamazole and cytostatics increase the risk of developing leukopenia.
The effect is enhanced codeine, Hg-histamine receptor blockers and propranolol (slows the inactivation of metamizole sodium).
If it is necessary to simultaneously apply the above and other medications, you should consult your doctor.
