How To Take Afrezza

Follow your doctor’s or healthcare provider’s recommendations when taking Afrezza.

Afrezza is a powder that you inhale using an inhaler through your mouth. Before you take your first dose, your doctor or pharmacist should show you how to use it. The producer of Afrezza, MannKind Corporation, also offers a video to show you how to use it.

Before you begin your meal, double-check that you have the correct amount of Afrezza cartridges for your dose. Make sure the cartridge has been at room temperature for at least 10 minutes before inserting it into the inhaler.

It should be used at the start of your meal (usually three meals per day). If you fail to take your medication before eating, your blood sugar levels may rise as a result of the food. Remember to take Afrezza as soon as possible. The dosage will be determined by your blood sugar level.

Set a reminder on your phone to help you remember not to skip a dosage. A medicine timer may also be beneficial.
