If you have diabetes and take insulin or other medications that affect blood glucose levels, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. It may be necessary to monitor your blood glucose levels more often when you are taking this medication.
