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
Using opioids for non-medical purposes increases the risk of dangerous side effects.
Already using naloxone
Naloxone* is a potentially life-saving tool for overdose reversal, but it cannot be self-administered during a life-threatening emergency.4

Know When to Take Action to Prevent Accidental Overdose
Monitoring is active
Alert 1: Caution
When physiological marker data shows high risk for overdose, alerts appear visually on the user’s mobile device and audibly at the Home Medical Hub, to facilitate self recovery.
Alert 2: Warning
As the risk level rises, the system alerts the user and sends automatic texts to you and other designated emergency contacts.‡
Alert 3: Emergency
If the risk level continues to worsen, the system triggers an automated wellness call that may lead to EMS being dispatched.
