With simultaneous application of Pllalgin and:
- non-narcotic analgesics there may be a mutual increase in toxic effects; allopurinol, oral contraceptives and tricyclic antidepressants the toxicity of Pllangin is increased;
- thiamazole and cytostatics increases the risk of developing leukopenia;
- cyclosporine reduces the concentration in the blood of cyclosporine;
- Butyrophenones, phenothiazines, tricyclic antidepressants, Hi- histamin blockers, amantadine and quinidine, the m-cholinoblocking effect of fenpiperinium bromide is enhanced;
- chlorpromazine or other phenothiazine derivatives may develop marked hyperthermia;
- Ethanol is enhanced by the effect of ethanol;
- phenylbutazone, barbiturates and other inducers of microsomal liver enzymes, the effectiveness of metamizole sodium decreases;
- sedative and anxiolytic drugs, the analgesic effect of metamizole sodium is enhanced;
- codeine, blockers of Hg-histamine receptors and propranolol, the action of Plenolgin is enhanced.
Metamizole sodium, displacing from the connection with proteins, oral hypoglycemic agents, indomethacin, indirect anticoagulants and glucocorticosteroids, can enhance their effect.
Radiopaque drugs, colloidal blood substitutes and penicillin should not be used during treatment with drugs containing metamizol sodium.
