Rapid-acting insulin

Rapid-acting insulin is a type of insulin used by people with diabetes to help control blood sugar levels. It begins to work quickly, usually within 15 minutes after injection, and is most effective around 1 to 2 hours later. This insulin is typically taken before meals to manage the rise in blood sugar that follows eating. Its quick action allows for flexibility in meal timing, but it also requires careful monitoring to avoid low blood sugar levels. Common brands include Humalog, Novolog, and Apidra.
