Patients were randomly assigned to receive a starting levothyroxine dosage of 25 mcg per day (low dose) or 1.6 mcg per kg per day (high dose). Levothyroxine doses were adjusted by 25 mcg every four weeks until 24 weeks.
The average full replacement dose of levothyroxine sodium is approximately 1.7 mcg/kg/day (e. g, 100-125 mcg/day for a 70 kg adult). Older patients may require less than 1 mcg/kg/day. Levothyroxine sodium doses greater than 200 mcg/day are seldom required.

In patients with moderate to severe signs and symptoms of hypothyroidism, start LEVOXYL at the full replacement dose (1.6 mcg per kg body weight per day). In patients with mild hypothyroidism (TSH less than 10 m. IU per liter) start LEVOXYL at 1 mcg per kg body weight per day.
