Acepromazine in liquid form for pets?

Acepromazine is a tranquilizer, which does not give pain relief.  It is used in veterinary medicine as a pre-anesthetic agent in horses, dogs and cats and is in a liquid form, which is injected. 

Imho, form is more hydrous than it is liquid

You can Google your quetion and there is a whole page on all kinds of drugs for animals in all kinds of situations. Also tells what drugs not to give with others. Was too long to print, but very informative.

Yes, Ace does come in liquid but not for injesting......It must be injected subcutaneously.  You should only use this under direction of a Veterinarian as it is pretty powerful stuff!
