Exubera® (inhaled insulin) is a prescription diabetes medication that is no longer being made. It was licensed to treat both type 1 and type 2 diabetes in adults. Unlike other forms of insulin that need to be injected, Exubera was different in that it was inhaled into the lungs through the mouth.
Pfizer announced in October 2007 that it would stop making Exubera, with a three-month window of availability after that date so that people could make the transition to a new diabetes medication. This decision was not based on any safety concerns surrounding Exubera; it was due to the medication not doing as well as expected in terms of sales.
