ALERT - it can bring on aggression in animals.
There is a risk of using anti-anxiety medications such as this in aggressive animals as a phenomenon called “disinhibition” may be observed. What this means is that the medication may remove whatever inhibitions the animal had to suppress aggression and the situation can be aggravated now that the patient is no longer inhibited. DO NOT ADMINISTER A PET'S FIRST-EVER DOSE OF ALPRAZOLAM AND THEN LEAVE HIM UNSUPERVISED. ALWAYS SUPERVISE A TEST DOSE TO BE SURE PETS ARE NOT OVER-TRANQUILIZED OR AGGRESSIVE WITH ONE ANOTHER.
