If you've already been diagnosed with an underactive thyroid, it's important to take your thyroid replacement hormone (levothyroxine) as directed by your doctor. There is no cure for an underactive thyroid. However, the condition can be successfully managed with levothyroxine (Synthroid, Levo-T, others).
