What is the typical administration frequency of intermediate insulin for glycemic control?

• A. Once daily
• B. Twice daily between meals and at night
• C. Three times daily
• D. As needed

Answer: (B)

Intermediate-acting insulin provides a basal level of insulin with a duration of roughly 12 to 16 hours. Because of this action window, it’s given twice a day to maintain steady background insulin coverage for fasting periods and overnight. Dosing about 12 hours apart helps keep glucose levels relatively stable between meals and during sleep, which is the goal of glycemic control with this type of insulin. Giving it once daily would allow the effect to wane too soon, leaving gaps in coverage and risking daytime hyperglycemia. Dosing three times daily is more than what's typically needed for basal control with intermediate insulin, and giving it only as needed contradicts the purpose of a basal insulin, which is to maintain a constant background level rather than reacting to highs.
