Benzodiazepines are a class of drugs used in both human and veterinary medicine as sedatives/hypnotics. They are also used as anti-anxiety medications, anti-convulsants (e.g., anti-seizure drugs), and as muscle relaxants. These drugs work by increasing the release of and/or facilitation of neurotransmitter gamma-aminobutyric acid (GABA) activity. When dogs and cats get into a toxic amount of benzodiazepines, clinical signs of severe sedation, incoordination, aggression, agitation, nausea, and vomiting may be seen. In severe cases, respiratory and cardiovascular depression may be seen.
