左旋甲狀腺素（Levothyroxine）用於治療甲狀腺功能低下，其機轉為補充外源性甲狀腺素。當藥物發揮療效時，病人的代謝率會恢復至正常水準。臨床護理師應評估「代謝過低」的症狀是否減緩，如疲倦、嗜睡、體重增加及便秘等。治療目標是使甲狀腺素數值（如 TSH）達到正常範圍，並改善病人的生活品質與能量狀態。
Levothyroxine treats hypothyroidism by restoring normal metabolic function, so increased energy levels indicate therapeutic effectiveness. Conversely, weight gain, increased heart rate, and decreased sweating are signs of untreated hypothyroidism or medication toxicity, respectively.
