Conventional multiple daily dosing of insulin gives the patient the greatest flexibility. In this approach, long-acting insulin (eg, glargine, detemir) is generally given once daily as the basal insulin, and rapid-acting insulin (eg, aspart, glulisine, lispro) is administered just before each meal.

The basal component can be administered at any time of day as long as it is given at the same time each day. However, interpreting glucose patterns is probably easiest if the basal insulin is administered at or near bedtime. The basal insulin can then be titrated to the morning sugar, and the bolus premeal insulin can be titrated to the next premeal sugar and, in some cases, a postprandial (2 h) value.
