Equimax Proven Safe in Pregnant and Nursing Mares

Horse Wormer Press Release


New York, NY (August 2004)—Equimax™, the leading equine combination dewormer in the US and the world, is now FDA approved as being safe and effective in pregnant and nursing mares, according to Pfizer Animal Health. Studies show the anthelmintic had no adverse effect on fertility and that mares treated with the paste had healthy foals even when given three times the recommended dose every three weeks throughout their breeding, entire gestation and foaling1.

Equimax Ivermectin / Praziquantel Paste De- Wormer

With the inclusion of its pregnant mare approval, Equimax is the only ivermectin/praziquantel dewormer to be proven safe in mares, young foals and stallions. Previous, worldwide studies on the anthelmintic have shown that stallions can be treated without affecting their fertility and that Equimax is safe for use in foals as young as four weeks of age.

“Horse owners can use Equimax with absolute confidence,” said Robert Dressler, DVM, Manager of Equine Veterinary Operations at Pfizer Animal Health. “This dewormer is not only very safe, but also extremely effective against a wide range of parasites, including tapeworms.”

Equimax was designed to provide a powerful solution to the newly understood threat of tapeworm (Anoplocephala perfoliata) infection in horses. Recent research conducted by Dr. Craig Reinemeyer of East Tennessee Clinical Research has shown that an average of 54% of horses in the U.S. have been exposed to the parasite. The study provides an exposure range of 12.7% of horses on the Pacific coast to a staggering 95.8% of horses in the upper Midwest 2.

Tapeworms congregate at the ileocecal junction—the meeting place of the small intestine, cecum and colon—attaching themselves to the sensitive mucosa of this area with strong hooks. This creates inflammation, swelling and even ulcers at the attachment site.

As a result, tapeworms are a leading cause of colic in horses. In a 1998 study published by Proudman, French and Trees, the researchers found that 22% of spasmodic (gas) colics were associated with tapeworms, along with 81% of ileal impactions3. Ileocecal intussusception—a potentially fatal colic condition—is almost always caused by tapeworm infection4.

Equimax is an apple-flavored paste and comes in a specially designed, ergonomic syringe and contains enough paste to dose up to 1,320 pounds of body weight. It has a sturdy, lockable dose adjuster, large print dosing scales on both sides, a curved finger grip and a shorter barrel for secure handling. The product’s palatable and smooth paste formulation is easy to administer as it slides quickly to the back of the tongue and down the throat.
