Hypokalaemic quadriparesis following torsemide and spironolactone use

Mild hypokalaemia is a common electrolyte abnormality following therapeutic doses of diuretics such as torsemide. If undiagnosed and untreated, hypokalaemia progresses and smooth muscle, skeletal muscle and the heart are affected. Potassium-sparing diuretics such as spironolactone are commonly added to loop diuretics to prevent symptomatic hypokalaemia. We present a patient with moderate hypokal-aemia associated with the use of torsemide and spironolactone, resulting in quadriparesis, hospitalization and electrophysio-logical abnormalities.
