Does modafinil expire?

Does modafinil’s patent or exclusivity ever expire?

Modafinil’s original drug exclusivity and patents have long since run their course, which is why the market is filled with generic modafinil. The key point for most people searching “does modafinil expire” is that modafinil is no longer under broad brand-only patent protection in many jurisdictions, so generics can launch.

If I mean “does modafinil itself expire” (drug expiration dates)?

Yes. Like other prescription medicines, modafinil tablets have an expiration date on the bottle. Expiration is about potencies and safety over time, not about patents or market exclusivity.

How to tell whether you’re asking about patent expiration vs. expiration date

• If you mean generics entering the market (patents/exclusivity): modafinil is already generic in most places.
  
• If you mean the medication going bad: check the expiration date printed on your specific package.
