Why do I need insulin at mealtime?

By: Suzanne Appel, MannKind Corporation

When you're living with type 2 diabetes, your body does not make enough insulin or it does not use it properly. Since insulin is the hormone that regulates the movement of sugar out of your blood and into your cells, not having enough insulin may cause your blood sugar level (also called blood glucose) to rise too high (hyperglycemia).1

Diabetes therapy is designed to manage blood sugar levels throughout the day and night, in order to prevent health complications. Over time, too much sugar in your blood can damage your large blood vessels. This could cause problems with the heart, brain and legs (macrovascular complications) and damage to the small blood vessels, causing problems in the eyes, kidneys, feet and nerves (microvascular complications).2

Long-acting, or basal, insulin stays in your body throughout the day and can help control your blood sugar when you are not eating. However, long-acting insulin may not manage the increase in blood sugar when you eat food. To control those mealtime blood sugar spikes your healthcare provider may prescribe a fast-acting mealtime insulin to better match the insulin to what your body needs. The chart below shows an example of the spikes in blood sugar levels that can happen with meals.3

Blood Sugar Control with Diabetes

Type 2 diabetes is a progressive disease. This means it may become more challenging to control as time goes on. If your healthcare provider prescribes insulin, it does not mean you or your body have failed. If you find your current therapy is not working for you, talk with your healthcare provider. It may be time to make changes to your therapy. If you notice typical symptoms of hyperglycemia such as tiredness, irritability, blurry vision, more frequent urination and thirst, call your healthcare provider.2 Through a combination of proper nutrition, exercise, medication and not smoking, the risk of most diabetes-related complications can be reduced.4

  • Afrezza is a man-made insulin that is breathed-in through your lungs (inhaled) and is used to control high blood sugar in adults with diabetes mellitus. 
  • Afrezza is not for use in place of long-acting insulin. Afrezza must be used with long-acting insulin in people who have type 1 diabetes mellitus. 
  • Afrezza is not for use to treat diabetic ketoacidosis. 
  • It is not known if Afrezza is safe and effective for use in people who smoke. Afrezza is not for use in people who smoke or have recently stopped smoking (less than 6 months).

Do not use Afrezza if you:

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins or herbal supplements.

Before you start using Afrezza, talk to your healthcare provider about low blood sugar and how to manage it.

  • Read the detailed Instructions for Use that comes with your Afrezza.
  • Take Afrezza exactly as your healthcare provider tells you to. Your healthcare provider should tell you how much Afrezza to use and when to use it.
  • Know the strength of Afrezza you use. Do not change the amount of Afrezza you use unless your healthcare provider tells you to.

  • Smoke.

Afrezza may cause serious side effects that can lead to death, including:

See “What is the most important information I should know about Afrezza?” at the top of this page.

  • Low blood sugar (hypoglycemia). Signs and symptoms that may indicate low blood sugar include:
    • Dizziness or light-headedness, sweating, confusion, headache, blurred vision, slurred speech, shakiness, fast heartbeat, anxiety, irritability or mood change, hunger.
  • Decreased lung function. Your healthcare provider should check how your lungs are working before you start using Afrezza, 6 months after you start using it and yearly after that.
  • Lung cancer. In studies of Afrezza in people with diabetes, lung cancer occurred in a few more people who were taking Afrezza than in people who were taking other diabetes medications. There were too few cases to know if lung cancer was related to Afrezza. If you have lung cancer, you and your healthcare provider should decide if you should use Afrezza.
  • Diabetic ketoacidosis. Talk to your healthcare provider if you have an illness. Your Afrezza dose or how often you check your blood sugar may need to be changed.
  • Severe allergic reaction (whole body reaction). Get medical help right away if you have any of these signs or symptoms of a severe allergic reaction:
    • A rash over your whole body, trouble breathing, a fast heartbeat, or sweating.
  • Low potassium in your blood (hypokalemia).
  • Heart failure. Taking certain diabetes pills called thiazolidinediones or “TZDs” with Afrezza may cause heart failure in some people. This can happen even if you have never had heart failure or heart problems before. If you already have heart failure it may get worse while you take TZDs with Afrezza. Your healthcare provider should monitor you closely while you are taking TZDs with Afrezza. Tell your healthcare provider if you have any new or worse symptoms of heart failure including:
    • Shortness of breath, swelling of your ankles or feet, sudden weight gain.

Treatment with TZDs and Afrezza may need to be changed or stopped by your healthcare provider if you have new or worse heart failure.
