Summary
Both drugs promote potassium loss, so combined use can cause hypokalemia, which may provoke muscle weakness and arrhythmias. The risk is greater with high steroid doses, prolonged use or underlying heart disease.
What this interaction means in plain words
Prednisone 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.
Prednisone belongs to Endocrine; Torsemide belongs to Cardiovascular.
Why it happens
Additive potassium wasting: loop diuretic action at the thick ascending limb plus mineralocorticoid effect of prednisone on the distal nephron.
What to do
Monitor serum potassium and magnesium regularly and replace as needed. Consider potassium supplementation or a potassium-sparing agent if hypokalemia persists.
What to ask your pharmacist
