Generic Name: Insulin Aspart

  • What is this medication and its most common uses?

    Novolog is a fast-acting insulin used to control high blood sugar in people with diabetes. Novolog is available as a prefilled pen, vial, and a cartridge.

  • What should I know when beginning and continuing on this medication?

    How does this medication work?

    Your body needs insulin to turn sugar into energy. Diabetes develops when your body does not make enough insulin or does not properly use the insulin it makes. Novolog may help control your blood sugar levels by allowing blood sugar to move from your bloodstream into your cells for energy.

    What are the beneficial effects of this medication and when should I begin to have results?

    What: Lowering your blood sugar to a normal level may prevent or delay potential complications associated with diabetes, such as blindness, kidney failure, or heart problems. Novolog works by controlling the rise in blood sugar when you eat. Using mealtime insulin in combination with a long- or intermediate-acting insulin will help you to balance out your blood sugar throughout the day.

    When: Novolog acts quickly and may manage your blood sugar at meal time.

    How do I know it is working?

    Check your blood sugar regularly and as your healthcare provider tells you to. Your healthcare provider will also do regular blood tests to measure your blood sugar levels and your hemoglobin A1C (measures your average blood sugar levels over a 2- to 3-month period). Stay on your prescribed diet and exercise program, as this will also affect the results of your blood tests.

    Less common side effects may include: low potassium levels in your blood, swelling of your hands and feet, weight gain, skin thickening at the injection site.
