Novolog Flex Pen

Novolog is a fast acting human insulin aspart that is commonly used in the treatment of diabetes. Insulin is a hormone that is naturally produced by the pancreas that converts sugar (glucose) to energy. Diabetes occurs when the body does not produce insulin or is unable to use insulin properly. If you pet has been diagnosed with diabetes, your veterinarian may prescribe an insulin as therapy. Insulin is commonly given by subcutaneous injections (under the skin). Novolog is a fast-acting insulin that works for a shorter duration of time, and is commonly given with meals to supplement the use of a long-acting insulin. The Novolog Flex Pen is an automatic insulin delivery device that features a dial for dosing and uses replaceable pen needles. Consult with your pet’s veterinarian before administering this product and follow their specific guidelines for use.
