Question: how long does it take to bring blood sugar down?
Answer: After subcutaneous administration, its onset of action occurs in 0.5 hours, peaks at 2.5-5 hours, and its duration of action is 4-12 hours. The standard strength of regular insulin is 100 U/mL (U-100), but 500 U/mL (U-500) insulin is increasingly used, but primarily in those with Type 2 diabetes.
