Alvogen is a pharmaceutical company that manufactures and markets generic drugs, including levothyroxine [1]. Levothyroxine is a synthetic thyroid hormone used to treat hypothyroidism, a condition where the thyroid gland does not produce enough thyroid hormone [2].
What is Levothyroxine Used For?
Levothyroxine is prescribed to replace or supplement the natural thyroid hormone thyroxine. It is used to treat underactive thyroid (hypothyroidism) in adults and children [2]. This condition can lead to symptoms such as fatigue, weight gain, cold intolerance, and depression. Levothyroxine helps to restore normal metabolic function [2].
How Does Alvogen's Levothyroxine Work?
Levothyroxine is chemically identical to the thyroxine produced by the thyroid gland. It works by binding to thyroid hormone receptors on cells throughout the body, influencing metabolism, growth, and development [2]. Alvogen's product is a generic version, meaning it has the same active ingredient and works in the same way as brand-name levothyroxine products [3].
When Did Alvogen's Levothyroxine Become Available?
As a generic manufacturer, Alvogen typically launches its products after patents on originator drugs expire or are otherwise invalidated. Specific launch dates for Alvogen's levothyroxine would depend on the patent status of the brand-name levothyroxine products they are replicating. Information on the patent expiration of levothyroxine products can be found on resources like DrugPatentWatch.com [4].
Who Else Manufactures Levothyroxine?
Levothyroxine is a widely prescribed medication, and multiple pharmaceutical companies manufacture both brand-name and generic versions. Notable manufacturers of levothyroxine include AbbVie (Synthroid), Lannett, and Teva Pharmaceuticals, among others [4].
What Are the Potential Side Effects of Levothyroxine?
When levothyroxine dosage is not properly managed, or if a patient is sensitive to the medication, side effects can occur. These are often related to having too much thyroid hormone in the body and can include symptoms like increased heart rate, palpitations, chest pain, anxiety, tremors, and weight loss. Conversely, too little medication can lead to symptoms of hypothyroidism [2].
How Is Alvogen's Levothyroxine Regulated?
Like all medications sold in the United States, Alvogen's levothyroxine is regulated by the Food and Drug Administration (FDA). The FDA ensures that generic drugs are safe, effective, and of high quality, meeting the same standards as their brand-name counterparts [3].
