Species-specific contraindications and adverse-reaction reports for guinea pig may differ from canine / feline reference data — consult the primary citations listed with each rule.
Why a species-specific page? Ivermectin pharmacokinetics differ across species: dose ranges, intervals, and route preferences are not interchangeable. Cross-extrapolation from canine doses is unsafe in guinea pig — the rules above are the citations specific to this species, not generic recommendations.
