![]() Rapid-acting insulin is often called mealtime insulin because its action curve most closely resembles the body’s normal release of insulin at mealtimes. ![]() Duration: how long the insulin continues to have some blood-glucose-lowering effect.Peak: when insulin has its greatest effect on blood glucose.Onset: when the insulin starts to lower blood glucose.The first step to figuring out when to take insulin and how much to take is understanding an insulin’s action curve.Īn insulin’s action curve has the following three phases: But learning when to take insulin and how much to take is challenging, because injected or infused insulin does not act exactly like insulin released from the pancreas. ![]() People who have Type 1 diabetes, in which the pancreas secretes no insulin or virtually no insulin, must inject or infuse insulin. People whose pancreas does not secrete insulin normally often must inject insulin or infuse it with an insulin pump. During illness, when insulin needs may rise, the pancreas just produces more. In people with normal insulin secretion, insulin production and release is a finely tuned feedback system that maintains blood glucose between about 70 mg/dl and 140 mg/dl at all times, no matter what or when a person eats or when he engages in physical activity. The amount of insulin that is released matches the rise in blood glucose from the food that is eaten. ![]() The second phase of insulin release is more gradual and occurs over the next hour and a half to three hours. The first phase starts within minutes of the first bite of food and lasts about 15 minutes. In response to food, larger amounts of insulin are secreted and released in two-phase boluses. On average, adults secrete about one unit of insulin per hour regardless of food intake.īolus insulin. Small amounts of insulin are released by the pancreas 24 hours a day.

As a result, the advice on when to take it needs updating. However, several years of experience and observation suggest that this advice may not be ideal for everyone who uses rapid-acting insulin. This advice is based on the belief that rapid-acting insulin is absorbed quickly and begins lowering blood glucose quickly. Since the first rapid-acting insulin, insulin lispro (brand name Humalog), came on the market in 1996, most diabetes experts have recommended taking it within 15 minutes of starting a meal (any time between 15 minutes before starting to eat to 15 minutes after starting to eat). ![]() One potential source of difficulty that you may not have thought of is how you time your injections or boluses of rapid-acting insulin with respect to meals.
