Summary
Both agents stimulate adrenergic receptors, so using them together can produce additive rises in blood pressure and heart rate and may provoke arrhythmias. The risk is greatest in patients with cardiovascular disease, hypertension or hyperthyroidism, and when epinephrine is given systemically.
What this interaction means in plain words
Epinephrine and Oxymetazoline 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.
Epinephrine belongs to Endocrine; Oxymetazoline belongs to Respiratory.
Why it happens
Additive alpha- and beta-adrenergic agonist pharmacodynamic effects.
What to do
Monitor blood pressure, heart rate and rhythm when both are used, and avoid repeated oxymetazoline dosing in patients receiving systemic epinephrine or with significant cardiovascular disease.
