What blood glucose monitoring precaution applies when patients with diabetes start indacaterol maleate (Onbrez Breezhaler)?

Plasma glucose should be monitored more closely when patients with diabetes start indacaterol maleate (Onbrez Breezhaler), as high inhaled doses of beta2-adrenergic agonists may increase plasma glucose; Onbrez Breezhaler has not been investigated in patients with poorly controlled diabetes.
