Insulin lispro, sold under the brand name Humalog among others, is a fast acting insulin analog. It was first approved for use in the United States in 1996, making it the first insulin analog to enter the market.[2]

Engineered through recombinant DNA technology, the penultimate lysine and proline residues on the C-terminal end of the B-chain are reversed. This modification does not alter receptor binding, but blocks the formation of insulin dimers and hexamers. This allows larger amounts of active monomeric insulin to be immediately available for postprandial injections.[3]

Insulin lispro has one primary advantage over regular insulin for postprandial glucose control. It has a shortened delay of onset, allowing slightly more flexibility than regular insulin, which requires a longer waiting period before starting a meal after injection. Both preparations should be coupled with a longer acting insulin (e.g. NPH insulin) or an insulin infusion pump for good glycemic control.

Medical uses[edit]

Insulin lispro is an FDA approved drug used to treat people living with Type 1 diabetes or Type 2 diabetes.[4] Insulin lispro has non-FDA labeled uses for diabetic neuropathy prevention and cardiovascular disease prevention.[4]

Side effects[edit]

Common side effects include skin irritation at the site of injection, hypoglycemia, hypokalemia, and lipodystrophy.[4] Other serious side effects include anaphylaxis, and hypersensitivity reactions.[4]


Do not administer insulin lispro during episodes of hypoglycemia, or if the patient has a hypersensitivity to insulin lispro or any of its excipients.[4]


In the United States, as of 2015, the cost is between $10.06 and $29.36 per 100 units.[5]

In Europe the price is far lower. The cost in the UK is between £1.66 (about $2.50) and £1.96 (about $3.00) per 100 units, as of 2017.[6]
