Humalog cartridges are filled with Insulin Lispro which is a fast acting man-made insulin. Insulin analogs are man-made used for the treatment of diabetes. Insulin Lispro is a fast acting insulin which is sometimes called a mealtime, or bolus insulin. This is because it is designed for use just prior to eating a meal to help prevent the fluctuations in your blood sugar levels that occur during and after a meal.
Humalog (Insulin Lispro) is a man-made fast-acting insulin analog created using genetic engineering. It is very similar in structure to naturally occurring human insulin. The minor modifications in structure give Insulin Lispro a rapid absorption and shorter delay of onset compared to naturally occurring insulin. It starts to work about 15 minutes after subcutaneous (under the skin) injection, achieving peak blood levels 30-70 minutes after, and lasts about two to five hours. It should be taken 15 minutes before your meal and, if necessary may be taken right after a meal within 20 minutes of the beginning of the meal).
Always follow your doctor’s directions about your dose amount and dosing schedule. Every case of diabetes is unique that’s why your schedule has been individualized specifically for you and your insulin needs. Your normal dose may be effected by changes the food you eat, your activity level, or work schedule.
