Transcript: Humalog is the brand name for insulin lispro, an insulin substitute used to treat diabetes, which was approved by the FDA in 1996.  Insulin lispro is a prescription medication which is available only under the brand name Humalog. This fast-acting synthetic product is almost identical to natural human insulin.  Here’s how insulin lispro works: The synthetic compound is made in a laboratory to closely resemble human insulin. When injected, it passes into the blood stream and allows blood sugar, or glucose, to be transferred into the cells of the body to be used as energy. This results in reduced blood sugar levels.  The drop in blood sugar that results from synthetic insulin makes Humalog a good choice for treating Type 1 diabetics. Insulin lispro is fast-acting, which means it starts working 15 minutes after injection and peaks half an hour to two and a half hours later. It is best used in conjunction with a longer-lasting insulin.  Insulin lispro must be injected and is sold in boxes of 5 disposable syringes. Dosages vary greatly depending on your doctor’s assessment of your insulin needs.  Insulin lispro should be injected 15 minutes before—or immediately after—eating, to keep your blood sugar from dropping too much. Be sure to use a new needle and prepare your insulin pen according to the instructions before every dose. Insulin injections can cause irritation or redness at the insertion site and can also result in low or high blood sugar levels, causing dizziness or confusion. Ask your doctor for a complete list of side effects.And tell your physician immediately if you experience fruity breath, rapid breathing, fainting, or any other significant changes.  Insulin lispro should not be taken by people who have allergies to insulin products and its use should be monitored carefully in people with kidney or liver disease. Ask your doctor for a full list of medications and conditions that should not be combined with Humalog.  Because of its fast-acting nature, Humalog can be useful for lowering blood sugar around mealtimes. However, it should always be used under the direct care of a physician. Please ask for and review all of the patient information provided by your doctor before taking this medication.  “The information in this video is intended to supplement, not substitute for, the expertise of your physician.
