Signs of an Overdose

An overdose occurs when an individual has consumed too much of a substance for the body to process.

No matter which substance a person may be dependent on, from alcohol to cocaine to heroin, overdose is always a possibility.

In fact, in 2014, opioid-related overdose deaths increased 14 percent from the previous year, according to the Centers for Disease Control and Prevention.

Each substance has its own signs of overdose. If you suspect you or someone else may be experiencing an overdose, call 911. This article is not intended to provide medical advice. Emergency services should be contacted immediately if anyone is in a potential overdose situation.

Alcohol Addiction Signs

Loss of consciousness during overdoseAlcohol overdose, more commonly known as alcohol poisoning, occurs when a person drinks more alcohol than the body can process in a specific amount of time. Since alcohol is a depressant, too much of it can essentially shut down an individual’s brain by depressing respiration. When breathing is slowed too much, it prevents oxygen from reaching the brain and can result in coma or death.

The body can process one standard drink per hour – about a blood alcohol concentration of approximately 0.015 per hour. Blood alcohol concentration depends on many factors, including age, gender, height and weight, what was eaten, and even genetics.

Some signs of alcohol poisoning include:

  • Loss of coordination
  • Loss of consciousness
  • Vomiting
  • Slow, irregular, and/or absent breathing
  • Seizures
  • Paleness or blue tinged skin
  • Stupor – being conscious but not responding

If individuals show any of these signs after consuming any amount of alcohol, the first course of action is to contact emergency services. Even after individuals become unconscious, their blood alcohol concentration can continue to rise, causing further damage. Home “remedies” for sobering up, such as taking a cold shower, drinking coffee, or eating greasy food will not reverse alcohol poisoning. Prompt medication attention should be sought.

When mixed with other drugs, such as heroin, sedatives, marijuana, and prescription medications, it may take less alcohol to cause a fatal overdose. For example, combining alcohol with medications for sleep can cause a coma, and combining alcohol with marijuana can cause a suppression of the gag reflex that could lead to individuals choking on their own vomit.

The best prevention tool in regards to alcohol poisoning is for individuals to monitor their alcohol intake and drink responsibly. While drinking, it is best for individuals to stick to a preset drink limit.


More than 8,200 people died from heroin overdose in 2013 – a rate that is nearly four times what it was in 2002. Opiate use is becoming more and more common, and individuals from all demographics are at risk.

Signs and symptoms of an opiate overdose can include:

  • Slow and difficult, shallow, and/or absent breathing
  • Contracted pupils
  • Slurred speech
  • Stupor
  • Vomiting
  • Choking or gurgling sounds
  • Loss of consciousness
  • Irregular, slow, weak, and/or absent heartbeat

If possible, someone should stay with the individual who has overdosed while another individual calls 911. The person staying with the individual in need of assistance should try to keep the individual awake – begin by telling the individual that emergency services are being contacted or that naloxone is being administered. If the person is unconscious, turn the individual slightly on their side with a bent knee for support if consciousness is not regained. This will prevent the person from choking on vomit.

Like alcohol, opiates are commonly mixed with other substances, such as cocaine. This can make individuals more susceptible to overdose.

In 2014, the United States Food and Drug Administration approved a prescription medication called Evzio – an injectable form of naloxone – that can be used by individuals, family members, and caregivers in the event of an opioid overdose. While naloxone can be a lifesaving medication, it does not negate the need for the involvement of emergency services. Naloxone also only works for opiate overdoses and will not work in the event of an overdose caused by another substance.

Stimulants and Cocaine

An overdose – which is sometimes referred to as overamping – on cocaine, meth, or other amphetamines can increase the risk of an overdose-related heart attack, stroke, or seizure. This may occur regardless of the dose

Prompt Help

Seek help as soon as possible for overdoseThe best prevention of drug and/or alcohol overdose is abstinence. If this is not possible, and an individual’s support system is aware of drug and/or alcohol abuse, the individual should be monitored whenever possible. This will increase the chances that emergency services will be able to save the individual’s life should an overdose occur.

If the person is unable to control substance use, professional treatment is recommended. Most addiction treatment programs involve both medical detox and comprehensive therapy to address the reasons that led to substance abuse. The best way to avoid overdose is by living a sober life in recovery, and treatment can make that happen.
