Acepromazine is a veterinary tranquilizer/sedative commonly used in dogs. It depresses activity in the central nervous system, making a dog calmer, drowsy, and less reactive. Veterinarians may use it before anesthesia, for restraint during procedures, or in some situations where sedation is needed.
After taking acepromazine, a dog may appear sleepy, relaxed, less coordinated, or weak. One important effect is blood-vessel dilation, which can lower blood pressure. Because of this, veterinarians use extra caution in dogs that are dehydrated, debilitated, elderly, or have certain cardiovascular problems.
Acepromazine does not provide pain relief, so it may be combined with pain medications when used around surgery or painful procedures. Its effect can vary considerably between dogs, which is why it should be given only at the dose prescribed by a veterinarian.
Contact a veterinarian promptly if a dog becomes extremely weak, collapses, has difficulty breathing, cannot be awakened normally, or develops other severe symptoms after receiving acepromazine.
