Euthyrox patent expires?

Euthyrox is a brand name for levothyroxine (levothyroxine sodium), used for hypothyroidism. There isn’t a single global “Euthyrox patent expiry.” Patent coverage depends on the country and on any specific patents for salt form, formulation, or manufacturing process.

- In most major markets, the core levothyroxine molecule and common salt/formulations are off-patent and generics are widely available.
- Some jurisdictions can still have active patents on particular formulations, delivery methods, or specific processes, which can delay generic competition for those specific products.

If you want a precise expiry date, please tell me:
- the country or market of interest (e.g., US, EU country, India, etc.)
- whether you’re asking about the active ingredient levothyroxine sodium or a specific Euthyrox formulation

With that, I can give you a more targeted answer or guide you to the appropriate patent databases (Espacenet, USPTO, Google Patents, etc.) to check current status.
