Binds to 50S ribosomal subunit, inhibiting bacterial protein synthesis. Concentrates in tissues with long half-life.
CONTRAINDICATED orally in rabbits and guinea pigs (fatal dysbiosis). May cause GI upset. Long tissue half-life means prolonged effect after discontinuation.
Species-specific contraindications and adverse-reaction reports for cockatiels may differ from canine / feline reference data — consult the primary citations listed with each rule.
