Clevor is the first and only FDA-approved product for emesis induction in dogs.

Its selective active ingredient and unique ocular administration make the process easy and injection-free — all of which add up to a quicker, less stressful process for veterinarians, veterinary staff, the dog, and owners.

Clevor is ready to work when veterinarians — and their patients — need it. 

96% of users said the administration was easy or very easy in a study conducted with 100 dogs in the Clevor group.1

Unlike other emetic options, Clevor does not need to be:

  • Requested from a compounding pharmacy
  • Resuspended or crushed to be administered
  • Flushed from the eye after administration


Clevor is indicated for the induction of vomiting in dogs.
