Furosemide 為高效利尿劑（Loop diuretic），主要副作用為低鉀血症，會影響心臟傳導功能。護理師需定期監測血鉀濃度，並觀察病人是否出現肌肉無力、心律不整等低鉀跡象，必要時配合補鉀醫囑。
Furosemide is a loop diuretic that promotes the excretion of potassium, placing the client at risk for hypokalemia. Monitoring serum potassium levels is the priority assessment to detect this common side effect, which can lead to serious cardiac dysrhythmias and muscle weakness.

台灣護理師常需提醒病人多攝取富含鉀離子飲食（如香蕉、柑橘），美國護理師則更偏向於衛教配合醫師開立口服鉀片。
