Warnings
Use with caution in patients with hepatic impairment. All oral hypoglycemic agents are capable of producing hypoglycemia. Proper patient selection, dosage and the instruction to the patients are important to avoid hypoglycemic episodes. It may be necessary to discontinue repaglinide and administer insulin if the patient is exposed to stress (fever, trauma, infection, surgery). At higher dosages sulfonylurea may block the ATP-sensitive potassium channel, which may correspond to an increase risk of cardiovascular events. Avoid the use of sulfonylurea at higher dosages (repaglinide daily doses >1.5 mg).
