Equine veterinarians agree that rotating between chemical classes is the key to creating an effective deworming program. Now, Pfizer Animal Health makes rotation simple for horse owners by offering year-round parasite protection in a program that includes three proven, safe and effective products from different chemical classes: Equimax, Anthelcide EQ and Strongid Paste.

 Administered separately, at intervals throughout the year, Equimax, Anthelcide EQ and Strongid Paste work together to offer a solid defense against internal parasite damage. In order to make scheduling the rotation as easy as possible, Pfizer has created a take-home calendar for horse owners. Available at retailers across the country beginning in July, this helpful guide indicates the suggested order in which to give the products and allows owners to record the dates on which dewormers were given, for trouble-free reference later in the year.

 “With the large number of dewormers available on store shelves, it can be difficult for horse owners to sort through them and create a rotational program that works and uses the best attributes of different chemical classes,” said Kristin Ruff, equine products manager at Pfizer Animal Health. “Our products give horse owners a simple solution for effective rotation and one source for all the deworming products they need throughout the year.”

 According to Pfizer Animal Health’s Rotational Deworming Calendar, the year begins in January or February with administration of Anthelcide EQ (oxibendazole) and continues in March or April with Equimax (ivermectin 1.87%, praziquantel 14.03%). In May or June the calendar suggests Strongid (pyrantel pamoate) Paste and the rotation continues over the rest of the year in a similar pattern. Pfizer recommends that horse owners consult their veterinarians before beginning any deworming program. Veterinarians can also help determine the risk for tapeworm exposure, which may dictate additional treatments throughout the year
