Enhanced blood-glucose-lowering effect & increased susceptibility to hypoglycemia w/ anti-hyperglycaemic agents, ACE inhibitors, disopyramide, fibrates, fluoxetine, MAO inhibitors, pentoxifylline, propoxyphene, salicylates & sulfonamides. Reduced blood-glucose-lowering effect w/ corticosteroids, danazol, diazoxide, diuretics, glucagon, INH, oestrogens & progestogens, phenothiazine derivatives, somatropin, sympathomimetics (eg, epinephrine, salbutamol, terbutaline), thyroid hormones, atypical antispsychotic medicinal products (eg, clozapine & olanzapine) & PI. May either potentiate or weaken the blood-glucose-lowering effect of insulin w/ β-blockers, clonidine, lithium salts or alcohol. May cause hypoglycaemia w/ pentamidine. Oral drugs eg, antibiotics. Paracetamol, OCs.
