Cytomel operates by supplementing the levels of triiodothyronine (T3) in the body, thereby stimulating the metabolic processes that are reliant on thyroid hormones. This hastens the metabolism of carbohydrates, fats, and proteins, besides influencing the body’s regulation of temperature, heart rate, and growth and development.
For individuals with hypothyroidism, Cytomel can provide relief from common symptoms such as fatigue, weight gain, cold sensitivity, and slow heart rate. Its effect is typically more rapid and can be more easily adjusted than that of T4 (levothyroxine) medications, making it a critical option in specific clinical scenarios.
