What is the peak time for long-acting insulin?

• A. Minimal peak
• B. 1-3 hours
• C. 4-6 hours
• D. 8-12 hours

Answer: (A)

Long-acting insulins are basal insulins designed to provide a steady, background level of insulin with little to no pronounced peak. This flat profile means there isn’t a distinct peak at a specific time after dosing, so the peak time is minimal. That contrasts with short-acting or regular insulin, which have clear peaks within a few hours. While some variability exists among different long-acting preparations, the characteristic feature is a minimal or flat peak, making the “minimal peak” the best answer.
