Overview of Levothyroxine

Levothyroxine is a synthetic form of the thyroid hormone thyroxine (T4). It is commonly prescribed to treat hypothyroidism, a condition where the thyroid gland does not produce enough hormones. Levothyroxine works by replacing the missing thyroid hormones in the body, helping to regulate metabolism and energy levels.

Levothyroxine is available in tablet form and is usually taken once a day on an empty stomach. It is important to follow the dosing instructions provided by your healthcare provider to ensure the medication is effective. Regular monitoring of thyroid hormone levels is also recommended to ensure the correct dosage of levothyroxine.

Common brand names for levothyroxine include Synthroid, Levoxyl, and Tirosint. It is important to take levothyroxine as prescribed and not to stop taking it without consulting your healthcare provider, as untreated hypothyroidism can lead to serious health problems.
