Compare Glyburide vs. Afrezza

Head-to-head comparisons of medication uses, side effects, warnings, and more.

Key takeaways

Glyburide (Glynase) and Afrezza (insulin human) are both medications used to manage diabetes, but they belong to different medication classes and have distinct characteristics. Glyburide is a sulfonylurea that works by stimulating the pancreas to release insulin, and it is taken orally, usually once or twice a day with meals. Afrezza, on the other hand, is an ultra rapid-acting insulin that is inhaled at the start of meals to help control blood sugar levels. While glyburide is only approved for Type 2 diabetes, Afrezza is approved for both Type 1 and Type 2 diabetes in adults. Glyburide is available in a generic form, whereas Afrezza does not have a lower-cost generic option. Common side effects of glyburide include low blood sugar, nausea, and weight gain, while Afrezza can cause low blood sugar, cough, and throat irritation. Glyburide may interact with other medications that lower blood sugar, and Afrezza is not recommended for people with lung conditions like asthma or chronic obstructive pulmonary disease (COPD).

  • Summary of Glyburide vs. Afrezza

    Summary for Sulfonylurea
    Prescription only

    Glyburide is taken by mouth to lower blood sugar levels for people who have Type 2 diabetes. This medication isn't meant to be taken alone, but in addition to eating a healthy diet and engaging in regular exercise. Glyburide is typically taken once or twice daily, depending on your dose.

    Summary for Insulin
    Prescription only

    Afrezza is an ultra rapid-acting inhaled insulin for adults with diabetes. It helps manage blood sugar levels from meals. You breathe in the medication through the mouth using the Afrezza inhaler usually at the start of meals. Common side effects are low blood sugar and cough. There's also a risk of bronchospasm (sudden narrowing of the airways), which can make it hard to breathe. So Afrezza (insulin) isn't for people with breathing problems like asthma or chronic obstructive pulmonary disease (COPD).
