Insulin is a hormone that works by lowering levels of glucose (sugar) in the blood. Concentrated (U-500) insulin is a long-acting insulin that starts to work several hours after injection and keeps working evenly for 24 hours. U-500 insulin is five times more concentrated than regular U-100 insulin.

U-500 insulin is used to improve blood sugar control in adults and children with diabetes mellitus who have significant daily insulin needs (more than 200 units per day).
