Inhaled Insulin (Insulin without needles)
In June 2014, the FDA approved Afrezza which is an inhaler with pre-measured, rapid-acting insulin to be used before meals.
Afrezza is not for diabetes emergencies such as diabetic ketoacidosis 糖尿病酮症酸中毒 (DKA). Common side effects of inhaled insulin are low blood sugar, a cough, and a scratchy or sore throat.
Patients, with smoking habbit or suffering form lung disease, such as asthma or COPD (Chronic obstructive pulmonary disease 慢性阻塞性肺病), shouldn’t use inhaled insulin.
How Inhaled Insulin Works
With an inhaler similar to the ones used by asthma patients, diabetics breathe a fine insulin powder into lungs. There, it enters blood through tiny blood vessels.
