Naloxone and Opioid Overdose in Quebec: Recognize and Respond

Recognize dangerously slow breathing, call 911, give naloxone and stay because its effect can wear off.

In an emergency, call 911. Use official resources and adapt the response to the level of danger.

Signs

The person is unresponsive, breathes very slowly, irregularly or not at all, makes abnormal snoring or gurgling sounds, has blue lips or pinpoint pupils. When unsure, treat as an emergency.

Call 911

Report abnormal breathing, give the exact address and follow instructions. Do not let fear of judgment delay the call.

Give naloxone

Use the kit as trained and labelled. Naloxone does not replace breathing support, CPR or emergency care. Give another dose at the stated interval if there is no response.

Support breathing

Use rescue breathing or CPR according to training and dispatcher instructions. Use an AED when indicated.

Stay

Improvement may be temporary and sudden withdrawal may cause agitation. Do not allow more substances. Use the recovery position if breathing and monitor.

Avoid harm

Do not use a bath, walking, coffee, stimulants, food or induced vomiting.

Get a kit

Naloxone is free at many Quebec locations. Check contents and expiry, store accessibly away from extreme temperatures and tell others where it is.

Reduce risk

Avoid using alone, use less after a break, avoid alcohol or sedative combinations and use local checking or supervised services.

After the emergency

Offer care without pressure or blame. Replace the dose that was used, record what happened and seek support for witnesses and loved ones as well.
