Summary
Inhaled epinephrine has some systemic absorption and adrenergic activity, and lisdexamfetamine increases catecholamines. Together they may raise heart rate and blood pressure and provoke palpitations or arrhythmias. The effect is generally modest with inhaled dosing.
What this interaction means in plain words
Epinephrine inhaled and Lisdexamfetamine 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
Additive adrenergic stimulation from direct receptor agonism and amphetamine-induced catecholamine release.
What to do
Monitor heart rate and blood pressure and use the lowest effective epinephrine dose. Be more cautious in patients with cardiovascular disease.
