Approximately 17% of fatal heroin overdoses are new users.

Approximately 17% of fatal heroin overdoses are new users. As mentioned above, other signs that someone is experiencing a heroin overdose include a history of drug abuse or co-morbid mental health issues.

Not surprisingly, on of the strongest indicators is a previous history of heroin overdoses.

Sadly, heroin overdoses often occur when tolerance is significantly reduced, such as after a prolonged period of abstinence.

According to recent British Medical Journal, the risk of death from overdose increases 7 times in the first 14 days of completing residential heroin addiction treatment or release from prison.

Individuals who snort, smoke or inject the amount of heroin to which they are accustomed after a period of abstinence are at high risk of overdosing.

What to Do in an Emergency?

Heroin overdose is not something that is always identifiable without medical intervention.

The "death rattle" is often mistaken for snoring and overlooked as a sign of a heroin overdose.

For example, the characteristic "death rattle" is often mistaken for snoring and overlooked. Heroin overdose rarely causes death immediately so the opportunity for fast responders to prevent death exists.

Treatment of any type of drug overdose should not be handled without trained medical assistance. In the case of heroin overdose, call 911 or the National Poison Control Center (855-681-1324) and/or go to a hospital immediately.

While waiting for trained medical treatment, the following emergency procedures can be put into effect, if available:

  • Try to wake up the individual.
  • Perform rescue breathing.
  • Administer Evzio (a naloxone hand-held auto injector approved by the FDA for use by family members and caregivers in emergencies).

How to Avoid a Heroin Overdose

Heroin overdose is preventable. The best way to avoid a heroin overdose is to abstain from injecting or snorting heroin in the first instance.

In lieu of abstinence, research findings suggest that a combination of the following may prevent both non-fatal and fatal heroin overdoses:

  • Increased treatment with naloxone or buprenorphine.
  • Peer-to-peer education.
  • Support groups like Narcotics Anonymous.
  • Utilizing supervised injecting facilities.
  • Increased availability of Evzio.

Treatment for Overdose

The combination of behavioral and pharmacological treatments is a more effective strategy for heroin overdose treatment.National Institute on Drug Abuse

Medication-assisted heroin addiction treatment is effective and provides critical recovery support for heroin overdose survivors.

According to the National Institute on Drug Abuse (NIDA) however, the integrated combination of behavioral and pharmacological treatments is a more effective strategy for most people.

To counteract the short and long-term neurological damage that can be caused by heroin addiction and overdose (including permanent brain damage), the use of buprenorphine and/or methadone can help to transition from an acute post-overdose stage to nascent recovery.
