Humanized monoclonal antibody that binds free IgE, preventing attachment to high-affinity IgE receptors on mast cells and basophils, reducing allergic inflammation.
Anaphylaxis risk — observe post-injection. Very expensive. Species-specific antibodies needed for veterinary use. Investigational.
Species-specific contraindications and adverse-reaction reports for cat may differ from canine / feline reference data — consult the primary citations listed with each rule.
Why a species-specific page? Omalizumab pharmacokinetics differ across species: dose ranges, intervals, and route preferences are not interchangeable. Cross-extrapolation from canine doses is unsafe in cat — the rules above are the citations specific to this species, not generic recommendations.
