Mechanism of action

Competes with arginine for absorption and incorporation. Theoretically suppresses herpesvirus replication by reducing arginine availability needed for viral protein synthesis.

Side effects & warnings

Efficacy debated in recent studies. Generally very safe. May cause GI upset at high doses. Commonly used for FHV-1 in cats despite limited evidence.

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

L-Lysine dosing in other species

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