Euthyrox Levothyroxine

Euthyrox is a widely recognized brand for the pharmaceutical ingredient levothyroxine sodium, used primarily to treat hypothyroidism and other thyroid-related conditions. The brand was developed by the German company Merck KGaA, which remains one of the oldest pharmaceutical and chemical companies in the world.

While the brand originated in Germany, Euthyrox is manufactured in multiple locations to meet global demand, including facilities in Darmstadt, Germany, and through various international subsidiaries. The ultimate owner is the Merck Group (Merck KGaA), which continues to lead in the healthcare, life science, and electronics sectors. It is important to note that Merck KGaA (the owner of Euthyrox) is a separate entity from the US-based Merck & Co. (known as MSD outside North America).
