These ranges are per kg. Enter your corn snake's weight to get the precise dose and draw-up volume — unit and concentration math done for you.
Inhibits lanosterol 14-alpha-demethylase (CYP51), blocking ergosterol synthesis in fungal membranes. At high doses, inhibits adrenal and gonadal steroidogenesis.
Hepatotoxic — monitor liver enzymes. Strong CYP inhibitor (many drug interactions). Requires gastric acid for absorption (do not give with antacids). Also used for Cushing's disease (adrenal steroidogenesis inhibition).
Species-specific contraindications and adverse-reaction reports for corn snakes may differ from canine / feline reference data — consult the primary citations listed with each rule.

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