FDA Expands Label for Zimecterin

The Food and Drug Administration (FDA) recently announced that it has approved additional label claims for Zimecterin (ivermectin), adding several species and stages of small strongyles to the list of parasites controlled by the equine dewormer.

The announcement means that Zimecterin is now proven to control a total of 60 species and stages of equine parasites, 32 of which are in the small strongyle group. With the expanded label, Zimecterin becomes the most comprehensive parasite control product ever available for use in horses, offering the broadest spectrum of protection against small strongyles.

Zimecterin is manufactured by Merial, the company that discovered ivermectin and developed it for use in horses. The expanded label claims will apply to all Merial equine dewormers, including Equimectrin (ivermectin) and the veterinary brand, Eqvalan (ivermectin).

The new labels were awarded to Merial brands of equine ivermectin after the Center for Veterinary Medicine (CVM) reviewed extensive company research, which identified the previously unlabeled small strongyles and confirmed the products were fully effective at controlling the additional species and stages.

According to Frank Hurtig, DVM, manager of Veterinary Professional Services for Merial, the expanded labels represent a significant milestone in equine parasite control. "This is great news for horse owners," said Hurtig. "Zimecterin has always offered unsurpassed protection against worms and bots, but these additional label claims confirm that it is the most comprehensive product in the history of equine deworming."

Hurtig said the expanded labels result from Merial's commitment to ensuring the continued efficacy and safety of its equine dewormers. "We have a responsibility to horse owners to provide safe and highly effective health care products and to support those products with ongoing research," said Hurtig. "The expanded label for Zimecterin is the culmination of research that has spanned several years."

According to Hurtig, the FDA will allow generic brands of ivermectin to add some of the additional parasites to their label claims, but not all of them. Several of the previously unlabeled species and stages of small strongyles are now labeled only for Zimecterin, Equimectrin, and Eqvalen.
