The starting adult dose of liothyronine to treat hypothyroidism is 25 µg daily. Based on the results of laboratory tests to determine the amount of thyroid hormone in your blood, your doctor will increase your dose of liothyronine gradually, every 1 to 2 weeks until an appropriate level of thyroid hormone is available in the bloodstream. Do not change the way you take this medication without consulting your doctor.
