Product Details


Humalog is a rapid acting insulin that is used for both Type 1 and Type 2 diabetes treatment and insulin lispro is a manmade (analog) biologic insulin. For Type 1 diabetes it takes the place of the insulin the patient’s body doesn’t produce sufficiently to lower blood sugar levels that would be elevated without it, and for Type 2 diabetes it counters the body’s developed insulin resistance so that sugar is taken out of the blood and moved into cells for energy. Humalog insulin also works for Type 2 diabetes treatment by chemically messaging the liver to produce less sugar so that less of it is directed into the bloodstream.


Standard dosage guidelines for Humalog are to administer injection 15 minutes before a meal or immediately after a meal.

Injection may be administered into one of 3 acceptable injection sites: thighs / abdomen (outside a 2” radius around navel) / back of upper arms.

Be sure to use a different injection site for every new injection, and to not inject at the same site twice. Repeated injections at same site will increase the chance of lipodystrophy.
