What is insulin lispro and how does it work?

Insulin lispro is a rapid-acting human insulin analog used to improve blood sugar control in people with diabetes. It is approved for type 1 diabetes in adults and children age 3 and older, and for type 2 diabetes in adults. As a mealtime (bolus) insulin, it is usually taken at meals and paired with a long-acting basal insulin and/or oral diabetes medicines. It can also be used in insulin infusion pumps.

The "1-unit dial" describes the prefilled KwikPen, which dials doses in 1-unit increments for precise dosing. Insulin lispro is the same active ingredient found in the brand Humalog; because insulin is a biologic, the manufacturer (Lilly) also markets an authorized lower-cost version labeled simply "insulin lispro" rather than a traditional AB-rated generic. Admelog is another brand of insulin lispro. A separate product, Lyumjev, is not the same medicine — its active ingredient is insulin lispro-aabc, an ultra-rapid formulation that is not interchangeable with standard insulin lispro.

Insulin lispro cost and savings without insurance

Because a lower-cost version of insulin lispro is available, it is generally more affordable than the original brand-name product, but the cash price still varies a lot depending on which pharmacy you use and where you live. That is exactly why comparing matters. Rx.com checks prices across more than 60,000 pharmacies so you can find the lowest price near you. Enter your ZIP above to see today's price and print a free coupon you can hand to the pharmacist.

The manufacturer, Lilly, also runs the Lilly Insulin Value Program, an official savings program for its insulins. Program terms and eligibility vary, so check Lilly's official website for current details. You cannot combine a manufacturer savings offer with an Rx.com coupon at the same time, but it is worth comparing both to see which gives you the better price.

Insulin lispro alternatives and related insulins

Insulin lispro is one of several rapid-acting mealtime insulins. A closely related option is insulin aspart, sold as Novolog; it works in a similar way and is used at meals. Versions of standard insulin lispro include the brand Humalog, Lilly's authorized lower-cost "insulin lispro," and the brand Admelog. Lyumjev (insulin lispro-aabc) is a related ultra-rapid mealtime insulin, but it is a distinct product and is not interchangeable with standard insulin lispro.

Rapid-acting insulins are different from long-acting basal insulins such as insulin glargine (Lantus), which provide steady background coverage rather than covering meals. Many people use a rapid-acting insulin at meals together with a long-acting insulin. Do not switch insulin products, brands, or manufacturers without talking to your provider, and compare prices for whichever product you are prescribed.

Safety information

Insulin lispro has no boxed warning, but the most important risk is hypoglycemia (low blood sugar), which can become severe and cause seizures, loss of consciousness, or worse. Risk rises with dosing errors, missed meals, or changes in activity. Low potassium (hypokalemia) can also occur. Rotate injection sites to lower the chance of skin changes (lipodystrophy), and never share pens or needles with anyone else because of infection risk.

Tell your provider about any allergic reactions, and about other conditions or medicines you take, since combining insulin with certain diabetes drugs (such as thiazolidinediones) can cause fluid retention or worsen heart failure. This is general information, not medical advice. Always follow your prescriber's and pharmacist's instructions.
