Humalog KwikPen is an insulin pen that contains insulin lispro which is used to treat diabetes.

This rapid-acting insulin works quicker than human insulin in the body as the insulin molecule has been changed slightly.

Humalog is to substitute for the lack of insulin created by the pancreas and works effectively to manage blood sugar levels.

It works very quickly and its duration is shorter than soluble insulin (2 to 5 hours).

Each Humalog KwikPen delivers 1–60 units in increments of 1 unit.

This disposable single-patient-use prefilled insulin pens contains a total of 300 units of Humalog.

Users can administer multiple doses. The dial allows you to give yourself from 1 to 60 units of insulin from a single injection. Each turn of the knob will click and delivers a single unit.

Each dosage is displayed in a window by movement of a dial. The dial moves slightly after using the pen which may sometimes go unnoticed. It will reach the end of the cartridge when all 300 units have been used.

Before using Humalog KwikPen be sure to read all information from your leaflet carefully and follow instructions as provided by your doctor or pharmacist.

Your doctor may advise using Humalog KwikPen along with longer-lasting insulin.
