Phenothiazine Tranquilizers for Dogs: Top 5 Acepromazine Options in Canada (2025 Vet-Reviewed Guide — What to Know Before You Choose)

Atravet Acepromazine Tablets is positioned as a cost-effective, generic phenothiazine tranquilizer for dogs, favored in high-volume clinics and practices where budget and supply reliability matter. Its primary advantage over branded options in this list is lower per-dose cost and broad availability, though it lacks some of the specialty formulations (injectable or liquid) and braded support services offered by market leaders.

Acepromazine Maleate Injection is the go-to sterile phenothiazine injectable for veterinary hospitals needing rapid, controllable sedation in dogs; its technical strength is the ability to administer precise IV/IM doses for acute procedures. Compared with oral tablets and solutions here, the injection commands a premium due to sterile manufacturing and clinic-focused utility, making it more expensive per unit but often more effective for in‑hospital use.

PromAce Tablets is the established branded phenothiazine tablet widely used by veterinarians for canine sedation, offering consistent formulation, clear labeling, and manufacturer support that many clinics prefer over generics. While typically priced above generics like Atravet, PromAce’s brand recognition, supply-chain consistency and regulatory backing make it attractive for practices that prioritize traceability and predictable performance.

Acevet Tablets differentiate themselves by focusing on palatability and owner-friendly tablet design for dogs, improving compliance compared with standard generic tablets; this formulation advantage can reduce dosing errors in outpatient settings. Financially it sits between low-cost generics and premium branded products, offering a balance of improved administration (flavored or scored tablets) with moderate pricing.
