Despite this, acepromazine does have some significant effects that must be considered. It can cause hypotension (lowering of blood pressure). This effect may be exaggerated in Boxers and there have been anecdotal reports of death of Boxers after the use of acepromazine. In addition, acepromazine seems to make it easier for dogs with seizure disorders to have a seizure.
This medication should not be used near the time of dipping or treatment with organophosphates for flea control.
