What Should I Know About Overdose Prevention?

Posted August 28, 2026

International Overdose Awareness Day | August 31

International Overdose Awareness Day is a time to remember those whose lives have been lost to overdose, support the families and communities affected, and share information that can help prevent future deaths.1

What are the signs of an opioid overdose?

An opioid overdose is a medical emergency. Warning signs may include:

  • Inability to wake up or respond
  • Slow, shallow, or stopped breathing
  • Choking, gurgling or unusual snoring sounds
  • A limp body
  • Blue, purple, gray or pale lips, fingertips, or skin
  • Small, constricted “pinpoint” pupils 2,3

If you suspect an overdose, call 911 immediately. Give naloxone (Narcan) if it is available and stay with the person until emergency help arrives. Naloxone can quickly reverse the effects of an opioid overdose and will not harm someone if opioids are not the cause of the emergency. 2,3

How can we better support someone struggling with substance use?

Substance use disorder is a treatable medical condition. Compassion, access to treatment and ongoing support can make an important difference.

Treatment for opioid use disorder may include FDA-approved medications such as buprenorphine, methadone, or naltrexone, along with behavioral health services, counseling, medical care, and recovery support based on each person’s individual needs. 4

Encouraging someone to talk with a healthcare provider — without judgment or stigma — can be an important first step toward treatment and recovery.

What is the most important message on International Overdose Awareness Day?

Overdose can be prevented and knowing how to respond can save a life.

Learn the warning signs, keep naloxone available when appropriate and remember that effective treatment and recovery are possible.

If you or someone you care about is struggling with substance use, reach out to a healthcare provider to learn more about treatment and support available in your community.
