indications for Buspirone HcL

Anxiety is a real problem, and not just one that affects people. For dogs and cats that suffer from anxiety or a phobia, it may be difficult to calm them down without medical assistance. Buspirone HcL is an anxiolytic, or anxiety reducing, drug that doesn’t act as a muscle relaxant or impair psychomotor activity in the same way as other anti anxiety medications, making it one of the only effective anti anxiety drugs that doesn’t sedate the recipient. Buspirone HcL is useful in the treatment of phobia related behavior and chronic anxiety in dogs and cats.


Buspirone HcL should be taken with caution in patients with liver or kidney disease, as well as in pregnant or nursing pets, only being given when the benefits greatly outweigh the inherent risks.

Taking buspirone HcL with MAOIs or furazolidone is contraindicated because of a risk of hypertension. Taking buspirone HcL with protein bound drugs has been known to result in the increased activity of both.


Dog -- Can be given anywhere between 2.5 - 15 mg, 2-3 times a day.
Cat -- Can be given anywhere between 2.5 - 5 mg, 2-3 times a day.
