What is ultra-long-acting insulin used for?

• A. Provides rapid postprandial glucose reduction.
• B. Used for immediate post-meal spikes.
• C. Provides basal insulin coverage for >42 hours, used for fasting glucose control.
• D. Raises HDL cholesterol.

Answer: (C)

Ultra-long-acting insulin provides a steady background insulin level to cover the body's baseline needs. Its action lasts well beyond a day—typically more than 42 hours—so it is used primarily to control fasting and overnight glucose, rather than addressing immediate post-meal spikes. This long, flat profile helps maintain stable blood glucose between meals and during fasting, reducing the risk of highs when you haven’t eaten. It’s not intended to rapidly lower glucose after meals, and it doesn’t have a role in raising HDL cholesterol.
