Summary
Epinephrine raises blood glucose and opposes insulin action, which can reduce the effectiveness of inhaled insulin. Glucose control may deteriorate during systemic epinephrine use.
What this interaction means in plain words
Epinephrine and Insulin inhaled can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Pharmacodynamic antagonism through increased hepatic glucose output and reduced insulin secretion.
What to do
Monitor blood glucose more closely and adjust the insulin dose as needed. Be aware that beta-agonist effects may also cause bronchospasm-related issues with inhaled insulin.
