Nicotinic acetylcholine receptor agonist causing sustained muscle contraction and paralysis in nematodes. Also has immunostimulant properties.
Narrow safety margin — toxicity causes cholinergic signs (salivation, tremors, dyspnea). TOXIC to dogs at high doses. Immunomodulatory use at low doses.
Species-specific contraindications and adverse-reaction reports for swine may differ from canine / feline reference data — consult the primary citations listed with each rule.
Levamisole dose range in swine, with cited source references: PO 8 mg/kg single dose in feed or water. Reference ranges from cited sources — verify against current literature before clinical use.
Documented routes for Levamisole in swine: PO.
Levamisole is indicated in swine for: GI nematodes, lungworms.
These are general warnings for Levamisole across species; consult the swine dosing table above for species-specific guidance. Narrow safety margin — toxicity causes cholinergic signs (salivation, tremors, dyspnea). TOXIC to dogs at high doses. Immunomodulatory use at low doses.
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.
