Naloxone and Overdose Safety

If you have been prescribed opioids to manage cancer pain, your doctor may also prescribe naloxone in case of emergency. Make sure the people you trust know when and how to use it.

If you see someone experiencing an opioid overdose, give naloxone and call 911 for emergency services. Training and naloxone kits may be available through your local health department. Video tutorials on when and how to use naloxone are also available through The Naloxone Project.

Signs of Opioid Overdose

Anyone taking opioids is at risk for accidental overdose. This is a medical emergency. If you or someone you know is taking opioids, make sure you know the signs of overdose:

  • Very slow, uneven breathing; in some cases breathing may stop completely

  • Slow heart rate

  • Does not respond to loud sounds or to rubbing firmly on the center of their chest

  • Lips and fingernails may turn blue, purple, or gray

  • Very small or “pinpoint” pupils

If someone is experiencing an overdose, give naloxone and call 911 for emergency services right away. Stay with the person until help arrives.

Naloxone FAQ

How to Use Naloxone

1. Check for Responsiveness

Look for signs of opioid overdose. If the person is not responding, try to wake them up by shouting and gently shaking them. Rub a fist firmly on the center of their chest for several seconds.

2. Administer Naloxone Nasal Spray

Each applicator holds one dose. Do not do a “test” spray.

  1. Tilt the person’s head back

  2. Hold the spray applicator with your thumb on the plunger.

  3. Insert the spray applicator into their nose.

  4. Press the plunger firmly to spray naloxone into the nose.

  5. Lay the person on their side. Naloxone may cause opioid withdrawal symptoms including vomiting. This position can prevent choking.

3. Call 911

Tell emergency services that you believe someone has experienced an opioid overdose and that you have given them naloxone. Follow any instructions from the dispatcher.

If the person does not respond after 2-3 minutes, or if they wake up but start to fall asleep again, give another dose of naloxone.

Stay with the person until EMS arrives. When EMS arrives, tell them you have given the patient naloxone.
