Phosphorylated to ara-ATP which inhibits viral DNA polymerase. Active against HSV and VZV. Largely replaced by acyclovir.
Poorly soluble — requires large IV volumes. Neurotoxic at high doses. Ophthalmic form better tolerated. Largely obsolete systemically.
Species-specific contraindications and adverse-reaction reports for cat may differ from canine / feline reference data — consult the primary citations listed with each rule.
Why a species-specific page? Vidarabine pharmacokinetics differ across species: dose ranges, intervals, and route preferences are not interchangeable. Cross-extrapolation from canine doses is unsafe in cat — the rules above are the citations specific to this species, not generic recommendations.
