Brief description of study

The purpose of this study is to find the effects of taking different doses of the thyroid medication levothyroxine in older people who already take levothyroxine for hypothyroidism.

Older people are more likely to have problems when their dose of levothyroxine is too strong. Allowing lower doses of levothyroxine would help prevent overmedicating older people with levothyroxine doses that are too strong.

Detailed description of study

The study involves 3 in person visits at Penn Research Center, 4 or 5 visits to your local Penn lab, and receiving 4 phone calls from study staff over approximately 8 to 10 months.
