Overdose Response

Responding to an Overdose

Knowing how to spot the signs of an overdose and how to respond appropriately to it are critical to saving someone’s life. We break down three common overdoses – Opioids, GHB and Stimulants – and offer tips on how to respond. 

Remember, if you need to call 911, inform the folks around you so they can decide if it is safe for them to stay (*police are often dispatched with EMS when a drug overdose is the cause of the call).

Opioid Overdose

Examples: Fentanyl, heroin, methadone

What to look for:

  • Slow or no breathing
  • Blue lips or fingertips
  • Unconscious or hard to wake
  • Cold, clammy skin

What to do:

  1. Give Naloxone (nasal spray or injection)
  2. Wait up to 3 minutes for it to work
  3. If no change, give a second dose
  4. Call 911 or go to the hospital—even if they wake up

Naloxone is free at many Ontario pharmacies and clinics. Find out more here.
