What is Levothyroxine?

Levothyroxine is a medication that is commonly prescribed to individuals who have an underactive thyroid gland, a condition known as hypothyroidism. The thyroid gland produces a hormone called thyroid hormone, which helps regulate the body's metabolism. When the thyroid gland is not producing enough hormones, it can lead to symptoms such as fatigue, weight gain, and depression.

Levothyroxine works by replacing the thyroid hormone that the body is not producing enough of. It is a synthetic form of the hormone known as T4, which is converted into the active form of the hormone known as T3 in the body. By providing this hormone, levothyroxine helps to restore the body's normal metabolic function and relieve the symptoms of hypothyroidism.

Levothyroxine is typically taken orally in the form of a tablet or liquid. The dosage and frequency of the medication will vary depending on the individual's specific condition and needs. It is important to take levothyroxine exactly as prescribed by a healthcare professional for it to be effective.

How does Levothyroxine work?

Levothyroxine is a medication used to treat underactive thyroid (hypothyroidism) by supplementing the body's natural thyroid hormone. The active ingredient in levothyroxine is a synthetic form of the hormone thyroxine, or T4.

Once ingested, levothyroxine is absorbed into the bloodstream and transported to the thyroid gland. There, it is converted into its active form, triiodothyronine (T3), which is the hormone responsible for regulating metabolism, growth, and development in the body.

By increasing the levels of T3 and T4 hormones in the body, levothyroxine helps to restore normal thyroid function and alleviate symptoms of hypothyroidism such as fatigue, weight gain, and depression.
