Summary
Epinephrine produces adrenergic stimulation, raising heart rate and blood pressure, while clonidine lowers sympathetic outflow. Systemic absorption from inhaled epinephrine is limited, but unpredictable blood pressure and heart rate changes are possible, and unopposed alpha effects may occur if clonidine is used chronically.
What this interaction means in plain words
Clonidine and Epinephrine inhaled have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Pharmacodynamic opposition between central alpha-2 agonism by clonidine and direct adrenergic agonism by epinephrine.
What to do
Monitor blood pressure and heart rate when inhaled epinephrine is used in a patient taking clonidine. Treat any hypertensive response symptomatically and avoid repeated high doses.
