Humalog Mix75/25, Humalog Mix75/25 KwikPen

What is this medication?

Humalog Mix75/25 and the Humalog Mix75/25 KwikPen are prescription insulin products used to improve blood sugar control in adults with diabetes mellitus. This medication consists of a mixture of two types of insulin: 75 percent insulin lispro protamine suspension, which is intermediate-acting, and 25 percent insulin lispro injection, which is rapid-acting. By combining these two forms, the medication helps manage glucose levels both immediately after eating and over a longer period during the day.

Patients typically inject this medication subcutaneously within 15 minutes before starting a meal. The rapid-acting portion begins to lower blood sugar quickly to handle the glucose spikes caused by eating, while the intermediate-acting portion stays in the system longer to provide steady insulin coverage between meals. Proper use involves following a healthcare provider's instructions for dosing and rotating injection sites to ensure effective management of diabetes.
