Synthroid is the brand name for a medication containing levothyroxine sodium [1].
What is Synthroid used to treat?
Synthroid is a synthetic thyroid hormone that is used to treat hypothyroidism, a condition where the thyroid gland does not produce enough thyroid hormone [2]. It is also used to treat or prevent goiter, an enlargement of the thyroid gland, and to manage thyroid cancer [2].
How does Synthroid work?
Synthroid replaces or supplements the thyroxine (T4) that the body's thyroid gland makes. Thyroxine is essential for metabolism, growth, and development [3].
When does Synthroid's patent expire?
Information on specific patent expiry dates for Synthroid can be found on DrugPatentWatch.com [4]. However, as levothyroxine sodium is a well-established medication with many manufacturers, multiple patents may apply over time, and generic versions have been available for a considerable period [4].
Who makes Synthroid?
The brand-name Synthroid is manufactured by AbbVie [1].
Can I get Synthroid as a generic?
Yes, levothyroxine sodium is widely available in generic forms from various pharmaceutical companies [4]. Because the drug has been around for a long time, generic options are common.
What are the alternatives to Synthroid?
Besides generic levothyroxine sodium, other prescription medications are available to treat hypothyroidism, including liothyronine sodium (Cytomel) and desiccated thyroid extract (Armour Thyroid) [5]. These options differ in their composition and how they are processed by the body [5].
What clinical data supports Synthroid?
Levothyroxine has been a standard treatment for hypothyroidism for decades, supported by extensive clinical research demonstrating its efficacy in normalizing thyroid hormone levels and alleviating symptoms [3].
What are the risks of taking Synthroid?
Like all medications, Synthroid can have side effects. These may include symptoms of hyperthyroidism if the dose is too high, such as rapid heartbeat, sweating, nervousness, and weight loss. It is crucial to take Synthroid exactly as prescribed by a healthcare provider [2].
