This product from ABBEY LABORATORIES is a generic brand for swine with ivermectin.

The original brand, IVOMEC PREMIX, was introduced in the 1980s as a specific oral formulation of ivermectin for swine.

Ivermectin was the first macrocyclic lactone discovered and introduced in the 1980s by MS&D AgVet (later MERIAL). It is the parasiticide for livestock and pets most widely used worldwide, with probably thousands of generic brands. Ivermectin is probably the best veterinary parasiticide ever developed, highly effective against roundworms as well as against numerous external parasites (ticksflies, lice, mites, etc.). As all macrocyclic lactonesivermectin used alone is ineffective against tapeworms and flukes, regardless of the delivery form.

There are also numerous mixtures of ivermectin with other active ingredients (not as premix for swine) as well as other formulations (injectables, pour-ons, drenches).
