Levothyroxine is typically known by what brand name?

Levothyroxine is primarily marketed under the brand name Synthroid. This medication is a synthetic form of the thyroid hormone thyroxine (T4) and is commonly prescribed to treat hypothyroidism, a condition where the thyroid does not produce enough thyroid hormone.

Synthroid is the most widely recognized brand for levothyroxine and has a well-established reputation for consistent quality and efficacy in managing thyroid hormone levels. Due to its popularity and clinical acceptance, it has become synonymous with levothyroxine therapy among both healthcare professionals and patients.

The other brands mentioned in the options pertain to different thyroid medications or combinations. Cytomel, for instance, is the brand name for liothyronine, which is a synthetic form of triiodothyronine (T3). Thyrolar is a brand name for a combination of levothyroxine and liothyronine, addressing different aspects of thyroid hormone replacement therapy. Armour Thyroid is a natural desiccated thyroid product that contains both T4 and T3, derived from animal thyroid glands. Each of these options serves a distinct purpose and contains different formulations that are not interchangeable with levothyroxine alone.
