What is an accidental opioid overdose?
An opioid overdose happens when the body has been overloaded with either a medication or an illicit opioid.
Accidents can lead to overdoses because while opioids affect the nerves that feel pain, they also affect the nerves that control breathing. If this slows breathing too much, a person can fall unconscious, experience a coma, brain damage or death.
It only takes 4 minutes
Permanent brain damage can occur within four minutes of oxygen deprivation.
Accidental opioid overdose is more common than you think
Accidental drug overdose is the leading cause of accidental death in the US.; most of these involve opioids.
Even when opioids are taken as prescribed by a healthcare provider, accidents can happen. You could accidentally take more than recommended. Your medicines may interact in ways you didn’t expect.
