Ivermectin patent status generic?

Short answer: In most places, the patent on ivermectin as the active ingredient has expired, and there are multiple generic versions available for both human and veterinary use. Merck’s branded product Stromectol still exists, but many generic manufacturers sell ivermectin tablets, suspensions, and injectables.

What to know:
- Some jurisdictions may still have patents on specific formulations, combinations, or new uses, plus any applicable regulatory exclusivities. Those can extend protection even after the basic drug is off-patent.
- Generic ivermectin is widely available in many markets, but exact status can vary by country and product type (human vs. veterinary).
- For precise, current status, check:
- US: FDA Orange Book
- Europe: European Patent Office / national patent registers
- Global: WIPO Patentscope or Espacenet
- Your country’s patent office

If you tell me your country and whether you’re asking about human or veterinary use, I can look up the current status and list some common generic manufacturers.
