Buspirone is an anti-anxiety medication that treats a range of fears, phobias, and anxious behaviors in dogs. Also commonly known by the brand name BuSpar, buspirone is a prescription drug that can take up to a few weeks to reach full effectiveness.
If buspirone has been prescribed for your pet, or if you’re looking for ways to help reduce your dog’s anxiety, keep reading for more information on its uses, efficacy, and side effects.
Buspirone is available in tablet form, with dosage strengths ranging from 5 milligrams to 30 milligrams. The dosage amount of buspirone depends on the size of the dog and the condition. However, the typical dose ranges anywhere from 2.5 milligrams to 15 milligrams 2 to 3 times a day. Make sure to follow your veterinarian’s dosage instructions when giving buspirone to your dog.
Buspirone for dogs is a prescription medication and should only be given on the advice of a veterinarian. It's sometimes combined with other sedatives or tranquilizing drugs. You can give buspirone with or without food.
The duration of treatment with buspirone varies depending on the condition and how the pet responds to the medication. However, single doses are unlikely to be effective, as buspirone may take a few weeks to achieve its full effects.
Stick to the dosage schedule recommended by your veterinarian. Your vet may also adjust the dosage level based on your pet’s response to buspirone.
Buspirone was first developed as an anti-anxiety medication for use in humans. It was designed to replace drugs like diazepam and can help manage anxiety with minimal sedation and muscle relaxation, plus no risk of addiction.
Buspirone for dogs most commonly treats mild, generalized fear and anxiety. It helps reduce anxious and abnormal behavior in dogs who suffer from fears and phobias, such as thunderstorm phobia or fear of loud noises.
While researchers don’t fully understand how buspirone for dogs works, it binds to serotonin receptors in the brain. Buspirone also increases prolactin, a hormone that enables socialization, and can help manage adaptation-related problems.
However, while studies show that buspirone is effective at treating urine spraying in cats, it doesn’t seem to be any more effective than benzodiazepines at controlling anxiety-related behaviors. It also has a delayed onset period of between 7 and 30 days, so it’s not recommended for cases of acute anxiety.
Finally, because buspirone has been anecdotally linked to the disinhibition of aggression, it may be better suited to treating anxiety in pets with no history of aggression towards humans or other dogs.
The cost of generic buspirone for dogs ranges from 10¢ to 75¢ per 5-milligram tablet.
The side effects of buspirone for dogs are generally quite rare. However, they can include:
