What special precautions are there?

  • Do not use in animals with allergy or hypersensitivity to this drug.
  • May lower blood pressure in animals by blocking nervous control of blood vessels. In some cases, may increase heart rate, and therefore should be used cautiously in animals with heart disease.
  • Drug reaction can lower blood pressure and cause heart arrhythmias in Boxers, and is therefore not recommended for this breed.
  • May cause sedation, but a paradoxical reaction of severe aggression or excitement may occur in some animals. Because of this, dogs on this medication should be gently handled and never left along with young children.
  • May worsen or initiate seizures or epileptic attacks in susceptible animals. Caution should be used when given to pets with seizure disorders, although it is best avoided.
  • Can lower body temperature, so pet should be kept warm.
  • May interact with other drugs. Contact your veterinarian to determine if your pet's other medications could interact with acepromazine. Such drugs include antidiarrheals, antacids, epinephrine, propranolol, barbiturates, and narcotics.
  • The most common effect is that your pet becomes relaxed, quiet, or more lethargic. Many may seem unsteady or uncoordinated. These effects are expected and could last for several hours following a dose.
  • After dosing, it is common for the animal's third eyelid to elevate. This is not a cause for concern as it is reversible.
