Eprinomectin dosing in other species
Why a species-specific page? Eprinomectin pharmacokinetics differ across species: dose ranges, intervals, and route preferences are not interchangeable. Cross-extrapolation from canine doses is unsafe in cattle — the rules above are the citations specific to this species, not generic recommendations.
