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 dog may differ from canine / feline reference data — consult the primary citations listed with each rule.
Why a species-specific page? Azithromycin pharmacokinetics differ across species: dose ranges, intervals, and route preferences are not interchangeable. Cross-extrapolation from canine doses is unsafe in dog — the rules above are the citations specific to this species, not generic recommendations.
