When are intermediate- and long-acting insulins usually taken?

A single shot of insulin can sometimes be enough to bring the blood glucose into the target range. Usually, a long-acting insulin or intermediate-acting insulin is given at bedtime or in the morning. The insulin is used to provide the basal level of insulin. Long-acting insulins provide a steady level of insulin throughout the day and night. Taking intermediate-acting insulin at bedtime helps lower your fasting glucose level. Taking intermediate-acting insulin in the morning provides some coverage for the food you eat as well as basal insulin.
