What is/are Insulin lispro?
Insulin lispro (marketed by Eli Lilly and Company as "Humalog") is a fast acting insulin analogue. It was first approved for use in the United States in 1996, making it the first insulin analogue to enter the market.
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 allowed larger amounts of active monomeric insulin to be immediately available for postprandial injections.
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 for good glycemic control.
Get emergency medical help if you have any of these signs of insulin allergy: itching skin rash over the entire body, wheezing, trouble breathing, fast heart rate, sweating, or feeling like you might pass out.
Hypoglycemia, or low blood sugar, is the most common side effect of insulin lispro. Symptoms of low blood sugar may include headache, nausea, hunger, confusion, drowsiness, weakness, dizziness, blurred vision, fast heartbeat, sweating, tremor, trouble concentrating, confusion, or seizure (convulsions). Watch for signs of low blood sugar. Carry a piece of non-dietetic hard candy or glucose tablets with you in case you have low blood sugar.
Insulin lispro can also cause hypokalemia (low potassium levels in the blood). Call your doctor at once if you have symptoms such as dry mouth, increased thirst, increased urination, uneven heartbeats, muscle pain or weakness, leg pain or discomfort, or confusion. Tell your doctor if you have itching, swelling, redness, or thickening of the skin where you inject insulin lispro.
