Every held source for this drug and species, as printed. Where they differ, both are shown — the choice is yours, not ours.
The sources disagree for this combination. The ranges below do not overlap on a comparable route. This is not an error in one of them — published veterinary references differ, and reconciling them for a particular patient is a clinical judgement.

Active form (calcitriol) binds VDR promoting intestinal calcium and phosphorus absorption, bone mineralization, and parathyroid hormone regulation.
Calcitriol: used for renal secondary hyperparathyroidism and hypoparathyroidism. Narrow therapeutic index — hypercalcemia risk. Monitor ionized calcium frequently. Do not confuse calcitriol with cholecalciferol.
Species-specific contraindications and adverse-reaction reports for houston toads may differ from canine / feline reference data — consult the primary citations listed with each rule.
