呋塞米是一種袢利尿劑，已知會導致鉀離子流失。低血鉀 (Hypokalemia) 可能引發心律不整等嚴重問題。若病人血鉀低於正常範圍 (3.5-5.0 mEq/L)，應暫停給藥並通知醫師，以避免加劇低血鉀。
Furosemide is a loop diuretic known to cause potassium loss. Hypokalemia can precipitate serious problems such as cardiac dysrhythmias. If the client's serum potassium is below the normal range (3.5-5.0 mEq/L), the medication should be held and the provider notified to avoid worsening the hypokalemia.

美國的臨床指南對電解質異常與利尿劑使用的界線較為明確；台灣的決策可能更依賴醫師的臨床判斷與病人的個別情況。
