Dose regimens4
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.

Adverse effects4
Autoantibody formation → refractory aplastic anemia — The feared complication — reason EPO is "last ditch," PCV in the teens first

Monitoring1
Clinical: PCV/Hct weekly until stable (titrate frequency), BP, serum iron/TIBC, reticulocytes; watch for abrupt PCV drop = antibody signal

The antibody clock: works beautifully until it stops working — a sudden PCV crash on stable dosing means anti-EPO antibodies (and cross-reactivity kills BOTH agents); darbepoetin post-epoetin failure may still buy time.

Darbepoetin's practical wins: once-weekly dosing (vs 3×/wk) in a cat that hates injections — the ÷200 units-to-µg conversion is the clinic-bench math.
