Barbituates have many forms and uses in both human and veterinary medicine. Some, like phenobarbital for example, are short term anesthestics commonly used as anticonvulsants for treatment of seizures in humans and animals. Other barbituates, like buprenorphine in Suboxone and Subutex, even Buprenex, are used to treat opiate addiction, and for pain control in surgical patients. If your pet has accidentally gotten ahold of any barbituate medication, or any medication not intended for them, please gather the rest of the meds and the bottle and call your vet or our 24/7 Help Line. Barbituates in high doses can be fatal. In fact, they're used in euthanasia solutions.
