Levothyroxine is the primary and standard treatment for hypothyroidism. This synthetic form of the thyroid hormone thyroxine (T4) is used to restore normal hormone levels in individuals who have an underactive thyroid gland. By replacing the deficient hormone, levothyroxine helps to alleviate symptoms of hypothyroidism such as fatigue, weight gain, and depression, while also supporting normal metabolism and overall bodily function.

The effectiveness of levothyroxine in managing hypothyroidism is well-documented, and it is typically delivered orally in tablet form, allowing for straightforward daily administration. Regular monitoring of thyroid hormone levels is also essential to ensure the dosage remains appropriate for the individual's needs, which further underlines the importance of levothyroxine as a cornerstone in the treatment of this condition.

Other options, like methimazole, are used for hyperthyroidism, while iodine supplements are not a standard treatment for hypothyroidism and might not be suitable for everyone. Thyroidectomy, which involves surgical removal of the thyroid, is not a treatment for hypothyroidism but may be necessary in cases of thyroid cancer or severe goiter.
