What You'll Learn

Risk factors: Binge drinking, age, and mixing substances
Binge drinking is a significant risk factor for alcohol overdose. Binge drinking is defined as a pattern of drinking that brings blood alcohol concentration (BAC) to 0.08% or 0.08 grams of alcohol per deciliter or higher. This typically corresponds to consuming five or more drinks for males and four or more drinks for females in about two hours. Binge drinking increases the risk of acute harm, such as blackouts and overdoses, and also raises the likelihood of unsafe sexual behaviour, unintentional pregnancy, and sexually transmitted infections. Additionally, it increases the risk of potentially fatal incidents, including falls, burns, drownings, and car crashes. Even a single episode of binge drinking can compromise the immune system and lead to acute pancreatitis in individuals with underlying pancreatic damage.
Age is another factor that influences the risk of alcohol overdose. Teenagers, college-age young adults, and adults between 35 and 64 years old are particularly vulnerable. Research indicates that younger individuals often engage in binge drinking and high-intensity drinking, which can overwhelm the body's ability to process and clear alcohol from the bloodstream. This results in rapid increases in BAC, significantly impairing brain and bodily functions. Lower BAC levels can be achieved in younger individuals with fewer drinks, increasing the risk of harm.
Mixing alcohol with other substances, such as opioid pain relievers or illicit opioids, is extremely dangerous. Alcohol and opioids suppress areas of the brain that control vital functions like breathing. Combining these substances intensifies their individual effects and can lead to an overdose, even with moderate amounts of alcohol. Additionally, drinking alcohol while using other drugs, including cannabis, can have stronger and more harmful effects than using either substance alone. It is crucial to avoid mixing alcohol with other drugs to prevent harmful and potentially deadly consequences.

Signs and symptoms: Vomiting, confusion, and seizures
Alcohol overdose, also known as alcohol poisoning, occurs when there is a high concentration of alcohol in the bloodstream, which causes areas of the brain that control vital functions such as breathing, heart rate, and temperature control to shut down. This can lead to permanent brain damage or even death.
Vomiting is a common symptom of alcohol overdose. Alcohol can irritate the stomach lining, leading to nausea and vomiting. In the context of an alcohol overdose, vomiting can be life-threatening due to the risk of choking on vomit. If you suspect someone is overdosing on alcohol, it is crucial to keep them in a sitting or partially upright position to prevent choking. If the person vomits, turn them onto their side while supporting their head and neck to ensure their airway remains clear.
Mental confusion is another sign of alcohol overdose. The person may exhibit impaired judgment, clouded thinking, and difficulty processing information. They may seem disoriented, have slurred speech, or struggle to understand basic questions or instructions.
Seizures can also occur during an alcohol overdose. Alcohol withdrawal, especially when sudden or involving large reductions in alcohol consumption over a short period, can trigger seizures in people with or without epilepsy. Long-term alcohol abuse can increase the risk of developing epilepsy, and repeated alcohol withdrawal seizures may make the brain more susceptible to future seizures, even in the absence of alcohol.
It is important to note that the presence of any of these symptoms in conjunction with excessive alcohol consumption warrants immediate medical attention. Do not wait for the person to exhibit all the symptoms, as alcohol overdose can rapidly lead to severe health complications and death. Call 911 or your local emergency number, and provide as much information as possible to the responders, including the amount and type of alcohol consumed, any medications the person is taking, and any known health conditions.

What not to do: Walking, cold showers, and leaving them alone
Alcohol overdose, also known as alcohol poisoning, occurs when there is a high level of alcohol in the bloodstream, which causes areas of the brain that control basic life-support functions such as breathing, heart rate, and temperature control to shut down. It is a potentially life-threatening condition that requires immediate medical attention.
If someone is showing signs of alcohol overdose, there are several things you should not do:
Walking
Do not try to get the person to walk or move around. This could make their condition worse, as their motor coordination and balance are likely to be impaired due to the high levels of alcohol in their system. Attempting to walk may lead to falls, injuries, or further complications.
Cold Showers
Avoid giving the person a cold shower or using any other methods such as hot coffee to try to "shock" them out of their intoxicated state. These methods do not reverse the effects of alcohol overdose and can be dangerous, potentially causing hypothermia or further disorientation.
Leaving Them Alone
Never leave a person alone if you suspect they are experiencing an alcohol overdose. They may need help with vomiting to prevent choking, and their condition can deteriorate rapidly. Stay with them, keep them sitting or lying down, and roll them onto their side while supporting their head and neck if they need to vomit.
It is important to call for emergency medical help immediately if you suspect someone is suffering from an alcohol overdose. Do not wait for them to exhibit all the symptoms, as their condition can quickly become life-threatening.

What to do: Call 911, keep them sitting, and prevent choking
Alcohol overdose is a medical emergency that requires immediate attention. If you suspect that someone has overdosed on alcohol, it is important to remain calm and take the following steps:
Call 911
Dial 911 immediately and explain the situation to the operator. Inform them that you suspect an alcohol overdose and provide any relevant information, such as the amount and type of alcohol consumed, any known medical conditions and allergies. It is crucial to seek professional help as soon as possible to ensure the person's safety.
Keep them sitting
While waiting for emergency services to arrive, assist the person in maintaining a sitting or upright position. This helps prevent choking and reduces the risk of falling. If the person is unconscious, place them on their side with an ear to the ground. This position, often referred to as the recovery position, helps to ensure their safety and prevents choking in case of vomiting.
Prevent choking
Alcohol overdose can cause vomiting, and the person may be at risk of choking on their own vomit due to a diminished gag reflex. Encourage the person to lean forward to prevent choking if they are conscious. If they are unconscious, placing them on their side with an ear to the ground helps prevent choking and ensures their airway remains clear.
It is important to stay with the person until help arrives and monitor their breathing and vital signs. Do not leave them alone, and avoid offering them food or attempting to treat the overdose yourself. Be honest with the emergency medical personnel about any substances the person may have consumed to aid in their treatment.

Treatment: Observation, monitoring, and medication
If someone is displaying signs of alcohol overdose, it is important to act quickly. Call emergency services immediately and try to collect information while waiting for them to arrive—for instance, the amount and type of alcohol consumed, as well as any other substances or medications taken. It is crucial that the person is not left alone. If they are conscious, sit with them and position them in a way that prevents choking and falls. If they are unconscious, place them on their side with an ear to the ground to prevent choking in case they vomit.
The treatment for alcohol overdose typically takes place in an emergency care setting and involves supportive care. This means that the treatment is designed to help manage symptoms and avoid complications. Medical staff will take steps to ensure the patient's medical stability and safety to aid their recovery.
Observation and monitoring are key aspects of treating alcohol overdose. Medical staff will closely monitor the patient's vital functions, including frequent assessment of breathing, to ensure that areas of the brain controlling basic life-support functions are not compromised. They will also protect the patient's airway from aspiration, which is crucial as alcohol can cause vomiting, even when unconscious, leading to a risk of asphyxiation and brain damage.
In addition to observation and monitoring, treatment may involve:
- Glucose administration if glucose levels are low
- Fluid hydration via IV to prevent dehydration
- Medication to address specific symptoms:
- Sedative medications may be administered if the patient is agitated, violent, or uncooperative. However, these can delay the elimination of alcohol from the body, so they are typically a last resort.
- Medications will also be given to manage any hypoglycemia and thiamin deficiency.
In extreme cases, where supportive care is ineffective, hemodialysis may be used to filter alcohol from the blood. However, this is uncommon.
