Nicotinic acetylcholine receptor agonist causing sustained muscle contraction and paralysis in nematodes. Also has immunostimulant properties.

Species-specific contraindications and adverse-reaction reports for swine may differ from canine / feline reference data — consult the primary citations listed with each rule.

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