What is the Humalog KwikPen?

The Humalog KwikPen (Humalog), also known as an insulin lispro injection, is a medication prescribed for both children and adult patients to treat diabetes. Humalog belongs to the drug classes, antidiabetics, and insulins. These medications work by improving and controlling your glucose levels.

What are the Indications for Humalog?

Humalog is approved to treat types 1 and 2 diabetes and control your blood sugar levels.

Your doctor may prescribe Humalog along with another longer-acting insulin. Do not change your dosage without consulting with your doctor. Your doctor or pharmacist will teach you how to adjust the dosage if you are ill or perform more strenuous physical activities.

Humalog is not recommended:

  • If you are allergic to insulin lispro or any ingredients in Humalog
  • If you suffer from low blood sugar (hypoglycemia)

How is Humalog used?
