Summary
Tricyclic antidepressants can enhance the cardiovascular effects of sympathomimetics. Inhaled epinephrine may produce more tachycardia, hypertension or arrhythmia, though systemic exposure from inhalation is limited.
What this interaction means in plain words
Epinephrine inhaled and Trimipramine 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
Trimipramine blocks catecholamine reuptake and sensitizes adrenergic receptors, amplifying epinephrine's effects.
What to do
Monitor heart rate, blood pressure and rhythm, especially with frequent dosing. Use the lowest effective epinephrine dose.
