Summary
Epinephrine causes a transient fall in serum potassium through beta2-receptor stimulation. When given with torsemide, potassium lowering may be additive and could promote arrhythmias in susceptible patients.
What this interaction means in plain words
Epinephrine racemic 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.
Why it happens
Beta2-mediated cellular potassium uptake added to loop diuretic renal potassium wasting.
What to do
Monitor serum potassium and cardiac rhythm when epinephrine is used repeatedly or in high doses. Correct hypokalemia before and during treatment.
