ASKED QUESTIONS

You have questions about Afrezza, we have answers. Below are answers to some frequently asked questions (FAQ). However, only your healthcare professional can help you decide if Afrezza is right for you. 

  • 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). 
  • It is not known if Afrezza is safe and effective in children under 18 years of age.

Afrezza is inhaled at the beginning of a meal. After you inhale Afrezza, the insulin passes quickly through your lungs and into your bloodstream where it begins reducing blood sugars.

Afrezza is unique because it is the only inhaled insulin available. It starts working quickly without the need for needles. Once you breathe Afrezza into your lungs using the inhaler, insulin appears in your bloodstream within 1 minute1 and it starts to work within about 12 minutes.2 

Afrezza has been proven to help control blood sugar levels in both type 1 and type 2 diabetes. If your diabetes medications are not giving you the control you need, adding Afrezza may help control the blood sugar spikes that happen when you eat. Afrezza does not replace treatment with long acting insulin.

If you have type 1 diabetes, you will still need to take a long-acting insulin. Your health care professional may prescribe Afrezza to treat mealtime spikes in blood sugar. If you are living with type 2 diabetes, your healthcare provider may consider adjustments to your other diabetes medications if they prescribe Afrezza.

Afrezza can be taken with oral diabetes medicines. Be sure to tell your healthcare professional about all other medicines and supplements you are taking because they can affect the way your insulin works.

Afrezza is a rapid acting insulin used to control blood sugar in adults with diabetes. It is not for people with certain types of lung disease (such as asthma or COPD) or who smoke. Do not use Afrezza if you are allergic to regular human insulin or any of the ingredients in Afrezza. Afrezza is not for children under 18 years of age. Consult with your healthcare provider to determine if Afrezza is right for you.

The most common side effects of Afrezza include low blood sugar (hypoglycemia), cough and sore throat or irritation.

Before prescribing Afrezza, your healthcare professional will perform an FEV1 breathing test to establish a baseline reading of your lung function. Your healthcare provider may test again at 6 months and once a year after that. The test measures how much air you breathe in and out, how long it takes for you to exhale completely, and is used to monitor your lung function over time. 

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. Read the detailed Instructions for Use that comes with your Afrezza.

A small amount of powder residue in the mouthpiece or cartridge is normal. This does not affect your dose.

Do not wash the Afrezza inhaler. You can wipe the mouthpiece with a clean, dry cloth to remove moisture or lipstick. 

Checking your blood sugar levels around mealtime, and keeping track of the levels, helps you and your healthcare professional monitor your progress over time and determine how well your treatment plan is working. Talk to your healthcare provider about what your blood sugar goal should be and when you should check your blood sugar levels.

Afrezza contains insulin. Hypoglycemia is the most common side effect with any insulin product. Severe hypoglycemia can cause seizures, may be life-threatening, or cause death. Talk to your healthcare provider to learn how to recognize the signs and symptoms of hypoglycemia and create an action plan in case of an episode of 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. 

In studies, cough was reported in about 27% of patients using Afrezza; 2.8% of patients gave cough as a reason for stopping Afrezza. Talk to your healthcare professional if you develop a persistent or recurring cough or breathing difficulties while taking Afrezza.
