Insulin to the Rescue ( Diabetes )
Insulin can help control high blood glucose levels, even if you have type 2. Doctors commonly prescribe it along with oral medications.
If your doctor asks you to take insulin at bedtime, he or she is probably concerned that your fasting (before breakfast) blood glucose levels are too high. When oral medications can’t keep your fasting blood glucose within the normal range by themselves, taking insulin at night can help. Your pills will work much better if your blood glucose level before breakfast is within the normal range. If this program does not work for you, you may have to take insulin both in the morning and at night, even though you have type 2 diabetes.
