Furosemide 若推注過快，可能造成耳毒性（ototoxicity），導致耳鳴或聽力受損。臨床建議靜脈推注時間至少應在 1 至 2 分鐘以上，以減輕對身體的衝擊。此為給予 Furosemide 的關鍵安全步驟。其他選項如平躺或檢查鉀離子數值雖為輔助性照護，但推注速率是給藥當下最重要的技術要求。
If furosemide is pushed too rapidly, it can cause ototoxicity, leading to tinnitus or hearing loss. The clinical recommendation is to administer IV push furosemide over at least 1 to 2 minutes to lessen the physiological impact. This is a key safety step when giving furosemide. Other options such as lying flat or checking potassium levels are supportive considerations but do not override the importance of injection rate at the moment of administration.
