Agri-Mectin Injection is a clear, ready-to-use sterile solution containing 1% ivermectin along with glycerol formal and propylene glycol. It is intended for subcutaneous administration in cattle and swine to treat and control gastrointestinal roundworms, lungworms, grubs, sucking lice, and mange mites. In cattle the injection is given under the loose skin in front of or behind the shoulder, while in swine it is given in the neck. The formulation delivers a persistent drug level that continues to protect against reinfection with several parasite species for one to four weeks after treatment. The bottle is a multiple-dose, rubber-capped container that should be stored at room temperature and protected from light. Consulting a veterinarian is recommended for assistance with diagnosis, treatment, and control of parasitism.
