Ojava organizes thyroid function labs, markers, and questions to help you prepare for conversations about levothyroxine with your clinician. This is general educational information, not medical advice.
What is levothyroxine?
A synthetic thyroid hormone used to treat hypothyroidism.
Drug class: Levothyroxine is a synthetic thyroid hormone that replaces or supplements the thyroid hormone your body would normally produce.
What it does: Levothyroxine provides the thyroid hormone T4 that your body needs when your thyroid gland does not produce enough on its own. It helps restore normal metabolism and energy levels.
FDA-approved uses: Hypothyroidism (underactive thyroid). Levothyroxine is sold under brand names including Synthroid, Levoxyl, and others.
