NOROMECTIN PREMIX from NORBROOK is one of the numberless generic brands with ivermectin.
The original brand, IVOMEC PREMIX, was introduced by MERIAL 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. 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 (ticks, flies, lice, mites, etc.). As all macrocyclic lactones, ivermectin used alone is ineffective against tapeworms and flukes, regardless of the delivery form.
