Who is at risk for an accidental opioid overdose?

Taking prescription opioids

Opioids can be an effective way to manage pain. However, all opioids carry a sedative effect, so even taking a prescribed dose can cause breathing to slow or stop.2,3

Non-prescription use

Using opioids for non-medical purposes increases the risk of dangerous side effects.

Already using naloxone
(e.g. Narcan®)

Naloxone* is a potentially life-saving tool for overdose reversal, but it cannot be self-administered during a life-threatening emergency.4
