Levothyroxine: Uses, Benefits, Dosage and Safety

Levothyroxine is a thyroid hormone medication that is often prescribed for hypothyroidism, a condition in which the thyroid gland does not produce enough thyroid hormone. Thyroid hormones control many body functions, so replacing the missing hormone can help restore normal thyroid function.

Levothyroxine is a synthetic version of the thyroid hormone T4. It is used to treat hypothyroidism, a condition where the thyroid gland does not produce enough thyroid hormones. Levothyroxine helps to replace the missing hormone and regulate the body’s metabolism, energy levels, and overall functioning. It is commonly prescribed to individuals with an underactive thyroid or those who have had their thyroid gland removed.
