EPRINEX is the new pour-on parasiticide from the makers of Ivomec that features no milk withholding or slaughter withdrawal – perfect for use in dairy or beef cattle. Its weatherproof formula kills a broad spectrum of roundworms, lungworms, grubs, lice, mange mites and horn flies. EPRINEX has been proven to control lungworms – including fourth-stage larvae – for 21 days and horn flies for 7 days after treatment. The dose rate is 1 ml per 22 pounds of body weight. It is not recommended for use in species other than cattle, and can be used in cattle over 8 weeks old.
