Afrezza insulin?

Afrezza is an inhaled form of insulin (regular human insulin in a dry-powder form) used to control blood sugar. Here are the key points:

What it’s for

• Used to treat diabetes (commonly for mealtime insulin in people with type 1 or type 2 diabetes).
• It’s typically used around meals, not as a replacement for long-acting basal insulin (for most people).

How it works / onset

• Fast-acting: starts working quickly and is designed to cover meal-related glucose spikes.
• Short duration compared with injected mealtime insulins.

How it’s taken

• Inhaled using a device (blister cartridges).
• Dose is based on your prescribed regimen and your blood sugar response.

Important safety / precautions

Afrezza acts through the lungs, so lung health matters:

• Do not use if you smoke or if you’ve recently quit (rules vary by situation—your clinician should guide this).
• Avoid/extra caution with chronic lung diseases, such as asthma or COPD (again, clinician guidance is essential).
• It can cause cough, throat irritation, and sometimes changes in breathing.
• There may be monitoring recommendations for lung function.

Hypoglycemia risk

• Like all insulin, it can cause low blood sugar (hypoglycemia), especially if meal timing or carbohydrate intake differs from expectations.

Common side effects

• Cough
• Throat irritation
• Headache
• Low blood sugar (most important)

Lung monitoring / when to call a doctor

Contact a clinician if you develop:

• New or worsening wheezing, shortness of breath, persistent cough, or breathing problems.

If you tell me what you mean by “Afrezza insulin” (for example: how it compares to other insulins, dose/how to take, side effects, or whether it’s appropriate for your situation), and whether you have type 1 or type 2 diabetes, I can tailor the answer.
