Insulin is a lifeline for millions with diabetes, helping regulate blood sugar levels when the body can’t produce enough on its own, a process critical for both Type 1 and Type 2 diabetes patients.
Rapid-acting insulin, like Novorapid and Humalog, starts working in 10-20 minutes and is ideal for controlling blood sugar spikes during meals, making it a go-to for Type 1 diabetes patients or Type 2 patients with significant post-meal glucose surges.
Scientific studies, including those from the American Diabetes Association, show rapid-acting insulin can lower blood glucose by up to 50 mg/dL within an hour of eating, closely mimicking the body’s natural insulin response to food.
Short-acting insulin, such as Actrapid and Humulin S, kicks in within 30-60 minutes and lasts up to 9 hours, often used by Type 2 diabetes patients who need a slightly slower but broader coverage for meals, especially when rapid-acting options are too fast.
Intermediate-acting insulin, like Insulatard and Humulin I, provides coverage for 10-18 hours and is typically used as a basal insulin for Type 2 patients to maintain steady glucose levels throughout the day, particularly for those on a combination therapy with oral medications.
Long-acting insulin, including Levemir and Lantus, offers a steady release over 24-36 hours with no peak, making it suitable for both Type 1 and Type 2 patients to manage baseline blood sugar levels, especially overnight or between meals.
A 2023 study from the Mayo Clinic highlights that long-acting insulins reduce the risk of nighttime hypoglycemia by 30% compared to intermediate-acting options, offering a safer profile for older adults or those with irregular eating patterns.
Cost-wise, rapid-acting insulins like Novorapid can retail at $300-$400 per vial without insurance, while long-acting options like Lantus may range from $250-$350, though prices dropped 10.6% between 2020 and 2023, per GoodRx data.
Short-acting and intermediate-acting insulins, such as Humulin S and Insulatard, are often more affordable, averaging $150-$200 per vial, making them a practical choice for patients with Type 2 diabetes who are cost-sensitive, especially those on Medicare plans capping insulin at $35 monthly.
Type 1 diabetes patients, who require insulin for survival, often benefit most from a combination of rapid-acting and long-acting insulins to mimic natural insulin production, while Type 2 patients may start with intermediate or long-acting options alongside oral medications.
Pregnant women with gestational diabetes or those with Type 2 diabetes experiencing acute illness, like diabetic ketoacidosis, may need rapid or short-acting insulin for tighter control, as intravenous insulin is often used in hospital settings for such cases.
Recent news highlights Novo Nordisk’s launch of an unbranded Tresiba (long-acting insulin) to improve affordability, reflecting a growing push for accessible diabetes care amid rising global diabetes rates, which hit 537 million adults in 2021, per the International Diabetes Federation.

Insulin is an essential treatment for managing diabetes effectively. Rapid-acting insulin can be highly effective for controlling blood sugar spikes after meals. Long-acting insulin offers a steady release, which is beneficial for maintaining baseline levels throughout the day and night. The cost of insulin can be a concern for many patients, especially without insurance. How do different types of insulin compare in terms of their effectiveness and affordability for patients with varying needs?
