Need the exact dose for your patient?
These ranges are per kg. Enter your peregrine falcon's weight to get the precise dose and draw-up volume — unit and concentration math done for you.
Inhibits fungal CYP51 (lanosterol 14-alpha-demethylase), blocking ergosterol synthesis. Broader spectrum than fluconazole including Aspergillus.
Drug of choice for aspergillosis. Hepatotoxic — monitor liver enzymes. Many CYP-mediated drug interactions. Visual disturbances in humans. Non-linear pharmacokinetics in some species.
Species-specific contraindications and adverse-reaction reports for peregrine falcons may differ from canine / feline reference data — consult the primary citations listed with each rule.
Voriconazole dose range in peregrine falcons, with cited source references: IM 12.5 mg/kg single dose studied. Reference ranges from cited sources — verify against current literature before clinical use.
Documented routes for Voriconazole in peregrine falcons: IM.
Voriconazole is indicated in peregrine falcons for: Aspergillosis.
These are general warnings for Voriconazole across species; consult the peregrine falcon dosing table above for species-specific guidance. Drug of choice for aspergillosis. Hepatotoxic — monitor liver enzymes. Many CYP-mediated drug interactions. Visual disturbances in humans. Non-linear pharmacokinetics in some species.
Why a species-specific page? Voriconazole pharmacokinetics differ across species: dose ranges, intervals, and route preferences are not interchangeable. Cross-extrapolation from canine doses is unsafe in peregrine falcons — the rules above are the citations specific to this species, not generic recommendations.
