It is a synthetic thyroid hormone.Synthroid contains the active ingredient levothyroxine, which is the only S drug currently approved to treat hypothyroidism. This drug has been studied in clinical trials, but its use to treat hypothyroidism has not been studied in combination with a synthetic thyroid hormone.

Synthroid is a brand-name (Rx) drug prescribed to treat hypothyroidism (under the brand name, levothyroxine). It belongs to a group of drugs called synthetic thyroid hormones.
Synthroid is approved by the FDA as a replacement for thyroid hormone replacement therapy (TTR) in hypothyroidism. TTR is a medication used to replace the thyroid hormone in individuals with an unrefreshed thyroid gland or other thyroid disorders.
TTR is a condition where the thyroid gland does not produce enough thyroid hormone, leading to symptoms such as:
Because Synthroid does not contain thyroid hormone, it is not recommended for use in patients with hypothyroidism. Also because it does not block the absorption of food- and beverages-related substances (such as iron, calcium, or phosphate) from the intestines, it cannot be absorbed by the digestive system.
Synthroid works by replacing the thyroid hormone that the thyroid gland produces. Specifically, the drug stops the body from producing enough thyroid hormone, resulting in the symptoms of hypothyroidism.
Synthroid contains the active ingredient levothyroxine, which is the synthetic form of the thyroid hormone thyroxine (T4). The drug is taken by mouth once or twice a day. Synthroid can be taken with or without food.
The dosage of Synthroid will depend on the thyroid hormone levels in the blood. The following are general guidelines:
The dosage of Synthroid will depend on the individual and the thyroid hormone levels in the blood.

Synthroid is a medication that is commonly used to treat hypothyroidism and certain thyroid disorders. It contains the synthetic form of the thyroid hormone thyroxine (T4) and works by binding to the thyroid gland’s thyroid hormone receptors in the small intestine. This binding process leads to the production of T4, a hormone that stimulates the body’s production of follicle-stimulating hormone (FSH) and luteinizing hormone (LH). This helps to slow down the process of thyroid hyperplasia and promote better thyroid function.
Synthroid binds to the thyroid receptors in the small intestine, which are responsible for hormone production. Once bound to the receptors, Synthroid prevents them from binding to the thyroid hormone receptors. This allows the thyroid gland to produce more thyroid hormones, leading to better thyroid function and better overall thyroid health.
Synthroid is available in tablet form, which is why you should always take it with a meal.
