Humalog® Mix50™ 100 units/ml KwikPen®

Each Humalog® Mix50™ KwikPen delivers 1-60 units in increments of 1 unit.

Humalog Mix50 KwikPen is a disposable pre-filled pen that contains insulin lispro. It’s formulation is slightly modified by one molecule. Humalog Mix50 contains 50% insulin lispro and is dissolved in water, available in a premixed suspension with protamine suphate to prolong the effects. It works faster than insulin produced by the body due to its formulation.

Diabetes is caused from the lack of insulin produced by the pancreas. Insulin is needed in the body to manage blood sugar levels. Humalog Mix50 is an effective substitute for your bodies insulin. It works longer and quicker than soluble insulin.

Humalog Mix50 pre-filled pens contain 3 ml (300 units, 100 units/ml) of insulin lispro. A single KwikPen contains multiple doses which can be adjusted by using the dial. The number units are displayed in a dose window and administer 1 unit at a time. Patients can administer 1-60 units in a single injection. If more than 60 units are required you will need to give yourself more than one injection.
