Acepromazine Maleate is a prescription medication for dogs who need tranquilization or for dogs who suffer from motion sickness. It’s used as a pre-anesthetic and as an anti-emetic to prevent vomiting due to motion sickness. This medication is not a pain reliever but can be used to sedate animals for minor procedures, such as nail trims. Best of all, it comes in a tablet form, so you can easily hide it in a pill pocket and give it as a tasty treat or disguise it in your dog’s favorite wet food. Customers may receive this drug under the names PromAce, Aceproject.


Acepromazine Tablets can be used as an aid in controlling intractable animals during examination, treatment, grooming, x-ray and minor surgical procedures.

Possible Side Effects

A few rare but serious occurrences of idiosyncratic reactions to acepromazine may occur in dogs following oral or parenteral administration. These potentially serious adverse reactions include behavioral disorders in dogs such as aggression, biting/chewing, and nervousness.

Drug & Food Interactions

Antacids and antidiarrheal medications may reduce the effectiveness of this medication. Before starting acepromazine, tell your veterinarian if your pet is currently taking phenytoin, antiarrhythmics like quinidine, or beta blockers such as propranolol. Other drug interactions may occur.


Tranquilizers are potent central nervous system depressants, and they can cause marked sedation with suppression of the sympathetic nervous system. Tranquilizers can produce prolonged depression or motor restlessness when given in excessive amounts or when given to sensitive animals. Tranquilizers are additive in action to the actions of other depressants and will potentiate general anesthesia. Tranquilizers should be administered in smaller doses and with greater care during general anesthesia and also to animals exhibiting symptoms of stress, debilitation, cardiac disease, sympathetic blockade, hypovolemia or shock. Acepromazine, like other phenothiazine derivatives, is detoxified in the liver; therefore, it should be used with caution on animals with a previous history of liver dysfunction or leukopenia.

    Drugs to calm my dogs

    By Laurie on Mar 17, 2021

    I have two hyperactive dogs (biological brother and sister) who are constantly in motion and bark all the time. Acepromazine has taken the edge off of them and they are so much nicer to be around. It has also helped with their fear of thunder and gunshot noise. I would recommend this drug for any dog who is excitable.

    Should’ve been cut by the pharmacist

    By Teddy on Aug 4, 2020

    I wouldn’t use it unless you really have to I use it for my dog for thunderstorms but the side effects are not good the next day he’s very groggy which is OK but he gets aggressive. These pills need to be cut up before they are delivered they didn’t cut them up for me and when you try to cut them yourself they break in pieces I have another medicine that I like it much better because they don’t hear the thunder as much he panics we had bad storms last night and hurricane warning so I had to give him the pill is used for emergencies only

    Acepromazine - my scardy pills

    By Sadiekins on Jun 13, 2020

    My humans ordered these pills for me because whenever there are fireworks, or thunder i am very scared. The pharmacy that they ordered them from gave my mum free shipping and the pills arrived really quickly. I love it when my humans give me these pills because i am able to sleep peacefully without shaking and without having to sit on my mums lap, even though i am a Labrador dog and weight 85 lbs. I recommend you get some of these pills!

    This product is amazing. After rescuing a bait dog and learning about his anxiety, this is the only product that can calm his anxiety to a manageable level for him. Would recommend this highly. We now have a much happier dog.
