Binds synaptic vesicle protein SV2A, modulating neurotransmitter release. Novel mechanism distinct from other anticonvulsants. Does not affect GABA or sodium channels at therapeutic doses.
Excellent safety profile. Minimal hepatic metabolism (renal excretion). No significant drug interactions. Sedation and ataxia initially (usually transient). Use extended-release if available (q12h instead of q8h). Safe in cats.
Species-specific contraindications and adverse-reaction reports for cats may differ from canine / feline reference data — consult the primary citations listed with each rule.

These are general warnings for Levetiracetam across species; consult the cat dosing table above for species-specific guidance. Excellent safety profile. Minimal hepatic metabolism (renal excretion). No significant drug interactions. Sedation and ataxia initially (usually transient). Use extended-release if available (q12h instead of q8h). Safe in cats.
Why a species-specific page? Levetiracetam pharmacokinetics differ across species: dose ranges, intervals, and route preferences are not interchangeable. Cross-extrapolation from canine doses is unsafe in cats — the rules above are the citations specific to this species, not generic recommendations.
