Naloxone is a medication that can temporarily reverse the effects of an opioid overdose and allow time for medical help to arrive.
Since June 2016, naloxone has been available for free through pharmacies, community organizations and provincial correctional facilities. This was in response to the opioid crisis, and in particular, the increase in overdose deaths. Fentanyl has been linked to many of these overdose deaths.
Fentanyl is an opioid that is prescribed as a skin patch. It is 100 times more powerful than morphine and used to treat severe pain. Most street fentanyl in Canada is produced illegally as a powder. It is increasingly found in street drugs, such as heroin and cocaine, and used to make tablets that look like prescription medications. Many overdoses have occurred because people did not know that what they were taking was contaminated with fentanyl.
If you or someone you know uses opioids or other street drugs, it is a good idea to have a naloxone kit.
Do I need this treatment?
A person may have overdosed if:
they can’t be woken and/or don’t respond to pain (e.g., pinching)
they are not breathing at all or are breathing very slowly
their lips and fingertips are turning blue or purple (in people with darker skin, their gums may be blue or purple)
they are making an unusual gurgling or loud snoring sound
their pupils are very tiny.
If someone is overdosing, call 911 right away! You can then use your naloxone kit while you wait for medical help.
What does Naloxone do?
Naloxone is an opioid antagonist. This means it blocks the effects of opioids, such as heroin, fentanyl, oxycodone and hydrocodone.It can restore normal breathing to a person whose breathing has shallowed or stopped as a result of an overdose.
Side effects of Naloxone
Naloxone is a relatively safe drug. Giving naloxone to a person that is unconscious because of a non-opioid overdose is unlikely to cause harm. However, naloxone will not reverse overdoses that are caused by non-opioid drugs (e.g., overdoses caused by alcohol or cocaine).
