In clinical trials of up to 2 years duration, a 15% or greater reduction in forced expiratory volume (FEV1) occurred in 6% of patients treated with inhaled insulin compared with a 3% decline in patients receiving comparator anti-diabetes treatment. Patients with chronic lung disease were not included in these studies. The FEV1 decline occurred during the first 3 months and persisted; it did not appear to worsen with increased duration of use. The changes in FEV1 were similar in patients with type 1 and type 2 diabetes mellitus.[Ref]
Very common (10% or more): Cough (25.6% to 29.4%)
Common (1% to 10%): Bronchitis, productive cough, decreased pulmonary function test[Ref]
The incidence of non-severe hypoglycemia in patients with type 2 diabetes was 67%. The incidence of severe hypoglycemia was reported at 5.1%. A severe episode was defined as a hypoglycemic event requiring assistance of another person and associated with either a blood glucose value consistent with hypoglycemia or prompt recovery following treatment. A non-severe episode was defined as symptoms of hypoglycemia with or without a low blood glucose value. The incidence of hypoglycemia was not reported for patients with type 1 diabetes.
