What is the peak action time for regular insulin?

The peak action time for regular insulin is typically around 2 hours after administration. Regular insulin is a short-acting insulin that starts to work within 30 minutes to 1 hour after injection, reaching its maximum effect (or peak) around the 2-hour mark. This peak occurs when blood sugar levels are likely to be the lowest as the insulin is effectively facilitating the uptake of glucose by the cells. Understanding this timing is crucial for effective diabetes management, particularly in planning meals and activity around insulin administration. Administering meals at the right times can help prevent hypoglycemia, making the awareness of this peak action time vital for safety in insulin therapy.
