When someone arrives at the hospital with alcohol poisoning, the medical team focuses on keeping them alive while their body processes the alcohol. There is no drug that reverses alcohol intoxication the way naloxone reverses an opioid overdose. Treatment is almost entirely supportive: maintaining breathing, preventing choking, correcting dangerous drops in blood sugar and electrolytes, and monitoring vital signs until the person stabilizes.
What Happens in the First Minutes
The emergency team starts by assessing how severely the person is affected. They check consciousness using a scoring system called the Glasgow Coma Scale, which rates eye, verbal, and motor responses on a scale from 3 to 15. A score below 9 signals that the person may not be able to protect their own airway, and that’s when the situation becomes critical. Staff also measure heart rate, blood pressure, breathing rate, and body temperature at regular intervals, often hourly, until things start to normalize.
Blood tests are drawn quickly. The team checks blood alcohol concentration, blood sugar, and electrolyte levels. Alcohol can cause blood sugar to plummet dangerously low, especially in people who haven’t eaten. It also disrupts potassium, magnesium, calcium, and phosphate levels in ways that can affect the heart. An electrocardiogram (ECG) is often run because alcohol can trigger abnormal heart rhythms, sometimes called “holiday heart syndrome.”
If the person is unresponsive, doctors also need to rule out a head injury. Someone found unconscious after heavy drinking may have fallen and hit their head without anyone realizing it. A physical eye exam looking for signs of increased pressure inside the skull, and sometimes a CT scan, helps determine whether the problem is purely alcohol or something more.
Keeping the Airway Open
The most dangerous immediate risk of alcohol poisoning is that the person stops breathing or chokes on their own vomit. Alcohol suppresses the gag reflex and, at high enough levels, slows breathing to a life-threatening degree. At blood alcohol concentrations above 350 mg per 100 mL, breathing becomes shallow, reflexes fade, heart rate drops, and the person may slip into a coma.
For most patients, the staff positions them on their side (the recovery position) and monitors their breathing closely. Supplemental oxygen through a mask may be used if oxygen levels dip. In more severe cases, roughly 6% of alcohol-intoxicated patients in one large study, a breathing tube is placed into the windpipe. The primary reason for this intervention is a consciousness score below 9, meaning the person is too deeply unconscious to keep their airway clear on their own. A smaller number of patients need the tube because they’re actively vomiting while unresponsive, have facial injuries blocking the airway, or simply can’t maintain adequate oxygen levels with less invasive methods.
IV Fluids and Electrolyte Correction
An IV line is started early. The standard fluid is normal saline, a simple saltwater solution. Despite being routine practice, the evidence that IV fluids speed up sobering is actually limited. Their main value is correcting dehydration (alcohol is a strong diuretic, and many patients haven’t been drinking water) and helping prevent metabolic problems like acidosis or dangerous shifts in sodium and potassium levels.
If blood sugar is low, the IV is used to deliver a concentrated glucose solution directly into the bloodstream. Doctors typically give a starting dose and recheck blood sugar within 15 minutes, repeating treatment until levels stabilize above 70 mg/dL. This matters because alcohol-induced low blood sugar can cause seizures and brain damage on its own, separate from the direct effects of alcohol on the brain. Children are especially vulnerable to this complication.
Thiamine and Preventing Brain Damage
Nearly every patient treated for alcohol poisoning receives thiamine (vitamin B1), usually by injection. This isn’t about treating the immediate intoxication. It’s about preventing a devastating brain condition called Wernicke’s encephalopathy, which can develop when a thiamine-deficient person receives glucose. Chronic heavy drinkers are frequently low in thiamine because alcohol interferes with its absorption, and the consequences of missing this step, permanent memory loss and brain damage, are severe enough that doctors give it as a precaution. For patients showing signs of malnutrition or heavy long-term drinking, higher doses are given for several consecutive days.
What the Hospital Cannot Do
There is no stomach pumping for alcohol poisoning. Alcohol is absorbed through the stomach lining so rapidly, within about 30 minutes of drinking, that by the time someone reaches the emergency department, the alcohol is already in the bloodstream. Activated charcoal, which works for some drug overdoses by binding to toxins in the gut, is equally useless here for the same reason.
There is also no way to speed up how fast the liver breaks down alcohol. The body metabolizes it at a fixed rate, roughly one standard drink per hour, and no medication or IV fluid changes that. The hospital’s job is to keep you safe while your body does the work.
Alcohol Withdrawal During the Stay
For people who drink heavily on a regular basis, a complication can emerge as blood alcohol levels fall: withdrawal. This can begin while the patient is still in the hospital and ranges from tremors, anxiety, and a racing heart to life-threatening seizures. Doctors watch for early signs and, when needed, use sedative medications to manage withdrawal safely. Additional medications may be used to control elevated blood pressure and heart rate. The threshold for experiencing withdrawal varies widely depending on how much someone normally drinks and for how long.
Regular heavy drinkers also present a diagnostic challenge on arrival. Tolerance shifts the relationship between blood alcohol level and symptoms dramatically. A person without tolerance might be in a coma at 350 mg per 100 mL, while a chronic drinker at the same level could still be conscious and talking. This means the medical team can’t rely on a single blood test to gauge how much danger someone is in. They have to watch the whole clinical picture.
How It’s Different for Children and Teens
When minors arrive with alcohol poisoning, the medical approach is largely the same but with heightened concern about two things: low blood sugar and breathing. Children’s livers are less equipped to handle alcohol, and their smaller glycogen reserves mean blood sugar can crash faster and more severely. Lower concentrations of IV glucose are used to avoid tissue damage.
Beyond the medical treatment, hospitals are required to assess the circumstances. Social workers typically evaluate whether the child has a safe home environment and reliable caregivers. If there are signs of neglect or an unstable home situation, child protective services may be contacted. For teenagers, the visit often includes a conversation about patterns of use and a referral for further support.
How Long the Hospital Stay Lasts
Most people with uncomplicated alcohol poisoning are in the emergency department for several hours. The team monitors vital signs, consciousness, and blood sugar at regular intervals until the person is alert, breathing normally, and able to walk and keep fluids down. For someone who required a breathing tube or developed complications like aspiration pneumonia (from inhaling vomit into the lungs), an intensive care stay of a day or more is possible. Patients who develop withdrawal symptoms may need to stay longer for medically supervised detox.
Before discharge, many hospitals offer a brief intervention, a short conversation about the episode and resources for reducing harmful drinking. It’s not mandatory, but it’s increasingly common, particularly for repeat visits or younger patients.
