Call a veterinarian or Pet Poison Helpline immediately for life-saving treatment advice. Do not administer to pets without veterinary consultation.

Why it's dangerous

These drugs act as hypnotics that affect the central nervous system; while intended for sedation, they often cause paradoxical agitation or severe depression of respiratory and cardiovascular systems in pets.

Toxic compound: Benzodiazepines or non-benzodiazepine hypnotics

Good to know

In cats, certain benzodiazepines can lead to acute liver failure. Paradoxical excitement (agitation/aggression) is common in pets despite these being sedative drugs for humans.
