The U.S. Food and Drug Administration (FDA) has approved a moxidectin/praziquantel product—Quest Plus Gel, produced by Zoetis—for use in breeding, pregnant, and lactating mares.

With this latest approval, Quest Plus joins Quest Gel as approved for use in breeding mares. The two are the only FDA-approved dewormers labeled to treat and control encysted small strongyles and bots in a single dose; Quest Plus is also labeled to treat and control tapeworms.

“The AAEP (American Association of Equine Practitioners) recommends treatment for tapeworms in late fall after a hard freeze,” said Kenton Morgan, DVM, an equine technical services veterinarian for Zoetis. “For effective treatment, horse owners should consult with their veterinarian and plan to deworm following a hard freeze in order to target tapeworms.”
