Which companies manufacture levothyroxine tablets and other forms?
Levothyroxine is made by many manufacturers worldwide, including branded-product makers and generic-drug companies. Which manufacturers apply depends on the specific product (brand name, tablet strength, gelcap/liquid form) and the country’s approved drug list.
How can I find the exact levothyroxine manufacturers for my prescription?
To identify the manufacturer(s) for the specific levothyroxine product you were dispensed, check the package label or pharmacy printout for the “manufacturer” or “marketed by” company name and the National Drug Code (NDC) (US). Then match that NDC to the product listing.
Are there different manufacturers for brand-name vs generic levothyroxine?
Yes. In most markets, branded levothyroxine has its own manufacturer, while generics are produced by multiple companies. As a result, two patients prescribed “levothyroxine” may receive products from different manufacturers even if the active ingredient and strength match.
What should patients watch for when the manufacturer changes?
Patients sometimes ask about whether a switch between manufacturers can affect thyroid control. Practical considerations include confirming the same strength and formulation, and monitoring thyroid labs (typically TSH) after a change if your clinician recommends it.
