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.
Select a species above to calculate a dose.

Monitoring1
Sedation score, HR/RR/BP through recovery; re-sedation for 2–3 h; analgesia adequacy post-reversal

Precautions6
No absolute contraindications; caution in geriatric/debilitated; IV in reptiles → profound hypotension (IM only)

Reversal removes ANALGESIA too — provide alternative (butorphanol) after painful procedures

The volume-equals-volume rule works because Antisedan (5 mg/mL) is exactly 5× Domitor (1 mg/mL) — inject the same number of mL IM. Understand the math, don't just memorize it.

You reverse sedation AND analgesia together — plan rescue analgesia (butorphanol/buprenorphine) before the anxiety of an awake, painful patient.

Shorter half-life than some agonists → resedation happens: keep the patient observed; redose as needed.
