Stopping low-dose thyroid hormone in older adults
Part of Hormones & metabolism clinical trials.
This study looks at whether it is safe to stop taking a low dose of levothyroxine (a thyroid hormone pill) in people aged 65 and older who have a mildly underactive thyroid. If you have been on this medication for at least 6 months, you may be able to help doctors learn if stopping the pill is a good option.
