Levothyroxine Sodium — products, DINs, and Canadian availability

This page lists Health Canada–registered pharmaceutical products whose active ingredient list includes Levothyroxine Sodium. We track 120 distinct Drug Identification Numbers (DINs) for this molecule, of which 39 are currently in marketed status. Across those registrations there are 16 manufacturers or marketing authorization holders, 4 dosage forms, and 30 distinct strength presentations.

Procurement teams normally arrive here for one of three reasons: a specific brand is unavailable and an equivalent registration is needed; a clinical protocol requires a comparator containing Levothyroxine Sodium in a defined strength; or a pharmacy needs to know which manufacturers still hold an active Canadian registration before committing to a substitution. The table below answers the first question directly. For the second and third, Nexara Health can confirm live availability, remaining shelf life, and landed cost from Canadian stock or from any of more than 40 regulated international source markets.

Registration status is not the same as availability. A product can hold marketed status in the Drug Product Database and still be on allocation, discontinued by the holder, or unavailable in the pack size a hospital needs. Where a Levothyroxine Sodium product is in shortage, our Canadian drug shortage tracker carries the reported status, the reason where the manufacturer has published one, and the marketed alternatives sharing the same active ingredient.
