Key takeaways
Glipizide / metformin and Afrezza (insulin human) are both medications used to manage diabetes. However, they belong to different medication classes and have distinct characteristics. Glipizide / metformin is a combination of a sulfonylurea and a biguanide used for Type 2 diabetes and it's taken by mouth. It works by stimulating insulin release and improving insulin sensitivity. Afrezza, on the other hand, is an ultra rapid-acting inhaled insulin used for both Type 1 and Type 2 diabetes, and it helps manage blood sugar levels after meals. While glipizide / metformin is available as a generic, Afrezza does not have a lower-cost generic option. Common side effects of glipizide/metformin include diarrhea, headache, and low blood sugar (hypoglycemia). Afrezza can also cause low blood sugar; cough is another common side effect. Glipizide / metformin should be taken with meals and Afrezza is inhaled at the start of meals. Afrezza is not recommended for people with lung conditions like asthma or chronic obstructive pulmonary disease (COPD).
