| Route | Dose | Frequency | Duration | Indication | Evidence | Source |
|---|---|---|---|---|---|---|
| IV | 0.5–5 mcg/kg/min | CRI | Until stable | Refractory hypotension (vasopressor) | Moderate | Ko J. Anesthesia monitoring techniques and management. Presented at: Proceedings: ACVC; 2009. PMID: 42484292 — Verified against Plumb's Veterinary Drug Handbook, 10th Ed, p.1043 (2026-08-01). |
One of the cited rules is a continuous-rate-infusion regimen: IV 0.5–5 mcg/kg/min CRI. CRI regimens are delivered as a continuous infusion rather than discrete doses — verify the rate against the cited source before use.

Selective alpha-1 adrenergic agonist causing vasoconstriction without direct cardiac stimulation. Increases SVR and blood pressure. Reflex bradycardia.
Pure vasopressor — no inotropic effect. Reflex bradycardia expected. Tissue necrosis with extravasation. Also used ophthalmically for mydriasis (2.5% — avoid 10% in small animals).
Species-specific contraindications and adverse-reaction reports for dogs may differ from canine / feline reference data — consult the primary citations listed with each rule.

Why a species-specific page? Phenylephrine pharmacokinetics differ across species: dose ranges, intervals, and route preferences are not interchangeable. Cross-extrapolation from canine doses is unsafe in dogs — the rules above are the citations specific to this species, not generic recommendations.
