levothyroxine
Synthetic thyroid hormone
Levothyroxine is a synthetic form of the thyroid hormone thyroxine, prescribed to treat hypothyroidism—an underactive thyroid gland.
It replaces or supplements the hormone the body fails to produce adequately.
Patients typically take it daily on an empty stomach: She takes her levothyroxine first thing in the morning.
Brand names include Synthroid and Levoxyl.
