Dose regimens3
This calculator performs arithmetic only on the sourced dosing field shown for each result — it does not verify the field's accuracy, does not select which field to use for a patient, and does not replace a veterinarian's order. Not for clinical use. Confirm every result against the primary source before dispensing.

Precautions4
May increase susceptibility to infection (incl. demodicosis) and could exacerbate neoplastic conditions — avoid high/prolonged twice-daily dosing

Reduce from twice-daily to once-daily after the 14-day induction period — this step-down is a core part of the label, not optional; prolonged BID dosing has a documented immunosuppressive signal (bone marrow, leukocyte effects).

Notably fast onset (within hours) compared to cyclosporine's multi-week lag — useful as a bridge or fast-acting option, including alongside cyclosporine during its induction period.
