Summary
Furosemide promotes urinary potassium loss and hypokalemia, so potassium supplements are often used with it intentionally. The effects oppose each other and the combination is usually appropriate.
What this interaction means in plain words
Furosemide and Potassium citrate have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Furosemide belongs to Cardiovascular; Potassium citrate belongs to Gastrointestinal Tract.
Why it happens
Loop diuretic inhibition of the Na-K-2Cl cotransporter increases distal potassium secretion, offsetting supplemental potassium.
What to do
Monitor serum potassium and renal function and titrate the supplement to results. Watch for hyperkalemia if renal function declines or the diuretic is stopped.
