Question: is 50 mcg of levothyroxine a lot?
Answer: There are two strategies for initiating levothyroxine in healthy adults younger than 65 years: low-dose (50 mcg) and full-dose (1.6 to 1.7 mcg per kg). Traditionally, lower starting doses of 25 to 50 mcg per day are recommended for patients 65 years and older or who have ischemic heart disease.
