Summary
Both drugs promote potassium loss, so combined use can cause hypokalemia. This increases the risk of weakness and arrhythmias, particularly in patients on digoxin or with cardiac disease.
What this interaction means in plain words
Dexamethasone 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.
Dexamethasone belongs to Endocrine; Torsemide belongs to Cardiovascular.
Why it happens
Additive renal potassium wasting from loop diuretic action and glucocorticoid mineralocorticoid effect.
What to do
