What are the signs of an opioid overdose and how can naloxone help?
Answer from Express Scripts Canada Pharmacist:
Thousands of people die each year from an opioid-related overdose. According to the Government of Canada, there were 15,393 apparent opioid-related deaths between January 2016 and December 2019.
The signs and symptoms of an opioid overdose can vary, depending on the type of drug taken, and whether it was taken alone or in combination with other substances.
In some cases, these overdoses may be avoidable if you know how to recognize some of the signs. Here is what to watch for:
- the person is dizzy or confused
- they can’t be woken up
- their breathing is slow or has stopped
- they are choking or making unusual snoring sounds
- their fingernails and lips have turned blue or purple
- their pupils are tiny or their eyes have rolled back
- their body is limp
If you think someone is overdosing:
After calling 911, you can administer naloxone if it is available.
Naloxone is a medication that blocks the effects of opioids and is used to counter the effects of an opioid overdose.
In Canada, Naloxone is available as a nasal spray and an injection.Take-home kits are also available at most pharmacies or local health authorities for anyone who is at risk of an overdose or who is likely to encounter one.
Naloxone can quickly reverse the effects of opioid drugs. When naloxone is given it blocks the opioid from affecting a person’s nervous system and reverses the effects. Naloxone can reverse slowed breathing within 3 to 5 minutes. A second dose of naloxone may be needed if the first dose does not restore normal breathing.
The effects of naloxone only last for 20 to 90 minutes. After naloxone wears off, the opioid may still be present and can cause breathing to slow down again. That means the overdose may return, requiring another dose of naloxone.
This is why it is important to seek medical help as soon as possible by calling 9-1-1, and then get ready to give a second dose of naloxone if the overdose symptoms return.
Naloxone is very safe and paramedics and emergency room doctors have used it for years to save lives.
Naloxone has no effect on a person if they have not taken opioids, so there is no risk of it causing addiction or dependence.
However, the person who has taken opioids might experience withdrawal symptoms after taking naloxone. Withdrawal is uncomfortable, but it is not life-threatening. In rare cases, some people may have an allergy to naloxone.
Remember, prescription opioids offer pain relief and taken as prescribed are safe when taken for a short time, but they can be misused. Knowing how to recognize the signs of an overdose and what steps to take to help someone by administering naloxone can save a life.
