Any horse - whether it is in a stall, on a pasture or at a show - can be infected by any number of harmful equine parasites.

Parasites can lead to a variety of health issues in horses including organ damage and respiratory problems. In addition, parasite infestations may contribute to colic, which sometimes results in expensive surgery or even death.

ZIMECTERIN® Paste 1.87% is an equine dewormer that provides effective treatment and control of the following parasites in horses:

  • Large strongyles
  • Small strongyles (including fourth stage larvae)
  • Pinworms
  • Ascarids
  • Hairworms
  • Large mouth stomach worms
  • Bots
  • Lungworms
  • Intestinal and neck threadworms
  • Summer sores

ZIMECTERIN® Paste 1.87% contains the active ingredient ivermectin. It is safe for use in all horses 6 weeks of age and older, including mares at any stage of pregnancy, and will not adversely affect stallion fertility. One syringe will treat a 1250 lb horse. Administer orally. Supplied as a single dose syringe.

To provide horses 2 months of age or older with the additional benefit of tapeworm control, we recommend Zimecterin® Gold Paste.

Merial backs every syringe of ZIMECTERIN® and ZIMECTERIN® Gold with a 100% Product Satisfaction Guarantee.
