Humulin N

Concomitant thiazolidinediones (TZDs) may cause fluid retention and heart failure; consider dose reduction or discontinue TZDs. Increased risk of hypoglycemia with concomitant antidiabetics, ACEIs, ARBs, disopyramide, fibrates, fluoxetine, MAOIs, pentoxifylline, pramlintide, propoxyphene, salicylates, somatostatin analogs (eg, octreotide), sulfonamide antibiotics. Reduced efficacy with concomitant atypical antipsychotics (eg, olanzapine, clozapine), steroids, danazol, diuretics, estrogens, glucagon, isoniazid, niacin, oral contraceptives, phenothiazines, protease inhibitors, somatropin, sympathomimetics (eg, albuterol, epinephrine, terbutaline), thyroid hormones. Variable effects with β-blockers, clonidine, lithium salts, alcohol, pentamidine. Concomitant β-blockers, clonidine, guanethidine, reserpine may blunt hypoglycemia. Onset may be delayed if regular insulin is mixed with zinc insulin. Regular and NPH insulins may be mixed and used immediately or stored for future use.
