Where It Comes From
Prescription medicine and hospital anesthesia; veterinary euthanasia solutions; waste from clinics and animal carcass disposal [1][2][3].
How You Are Exposed
Taking it as a medicine; misuse; accidental swallowing by children or pets; handling euthanasia solutions in vet settings; pets eating contaminated food or scavenging euthanized animals [2][3].
Why It Matters
Causes drowsiness, poor coordination, slowed breathing, low blood pressure; high doses can be fatal; mixing with alcohol, opioids, or other sedatives greatly increases risk; repeated use can lead to dependence and withdrawal [2][4].
Who Is at Risk
People using other depressants or with breathing or liver problems; pregnant people, children, and older adults; veterinary staff; pets and wildlife that access euthanized animals [2][3].
How to Lower Your Exposure
Use only as prescribed; avoid alcohol/other sedatives unless directed; store locked, out of reach; dispose via take-back or FDA-recommended methods; follow workplace safety and local rules for handling and disposing of euthanized animals [2][3][5].
