Summary
Epinephrine drives potassium into cells, and with loop diuretic potassium loss this can produce hypokalemia. Low potassium raises the risk of ventricular arrhythmias.
What this interaction means in plain words
Epinephrine and Torsemide 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; Torsemide belongs to Cardiovascular.
Why it happens
Beta-2 mediated intracellular potassium shift added to renal potassium wasting from the diuretic.
What to do
Monitor serum potassium and ECG when epinephrine is given systemically to patients on torsemide, and replace potassium as required.
