If someone near you is throwing up drunk, the most important thing you can do right now is get them on their side and stay with them. Vomiting while intoxicated is dangerous because alcohol suppresses the gag reflex, which means a person can choke on their own vomit, especially if they’re lying on their back or losing consciousness. Everything else, including hydration, comfort, and recovery, comes after you’ve secured their airway and confirmed they’re breathing normally.
Get Them Into the Recovery Position
The single most protective thing you can do is roll the person onto their side. According to the Cleveland Clinic, the correct position has three elements: they should be on their side, with their face angled slightly downward, and their head positioned a little lower than their stomach. This lets vomit drain out of the mouth instead of pooling in the throat or being inhaled into the lungs.
If they’re flat on their back, move the arm closest to you out to the side in an L-shape, roughly even with their head. Then take their far hand and use it to help roll them toward you. Bend their top knee forward so it acts as a kickstand, preventing them from rolling onto their face. Place the back of your hand near their mouth so you can feel their breath. If the back of your hand is slightly wet, you’ll feel even faint breathing more easily.
Do not leave them on their back, even for a few minutes. Alcohol dulls the reflexes that normally protect the airway, so a person who seems fine one moment can silently aspirate vomit the next. This is the leading cause of alcohol-related choking deaths, and it is almost entirely preventable.
Know When to Call 911
Vomiting alone doesn’t always mean someone needs an ambulance, but it’s one of several signs of alcohol overdose. The NIAAA lists these critical warning signs:
- Breathing problems: fewer than 8 breaths per minute, or gaps of 10 seconds or more between breaths
- Loss of consciousness: they can’t be woken up, or they drift in and out
- Seizures
- Skin changes: clammy skin, bluish or very pale color, extremely low body temperature
- Mental confusion or stupor beyond typical drunkenness
You do not need to see all of these before calling for help. Even one or two is enough. A person who has passed out and cannot be woken can die from alcohol poisoning. Blood alcohol levels above 0.31% can cause loss of consciousness, breathing failure, or coma, and the person may still be absorbing alcohol from their stomach even after they’ve stopped drinking.
Stay With Them and Monitor Breathing
Once you have them on their side, your job shifts to monitoring. Check their breathing every few minutes. Count breaths over 30 seconds and double it. If you’re getting fewer than 8 breaths per minute, call 911. Watch for long pauses between breaths, and listen for gurgling or choking sounds, which could mean vomit is partially blocking the airway.
Try to keep them awake if you can. Talk to them. Ask simple questions. If they stop responding to voice and gentle shaking, that’s a significant escalation. Don’t assume they’re “just sleeping it off.” The difference between deep sleep and dangerously depressed consciousness isn’t always obvious, so err on the side of getting help.
What Not to Do
Several common instincts actually make things worse. Coffee and other caffeinated drinks don’t sober anyone up. As Harvard’s health guidelines put it, you’ll just end up with a wide-awake, agitated drunk person. Caffeine doesn’t speed up the metabolism of alcohol, and agitation can make the situation harder to manage.
A cold shower is another popular idea that’s genuinely dangerous. The shock of cold water can cause a drunk person to pass out or fall, risking head injuries in an already impaired state. Walking them around to “burn off the booze” doesn’t work either, since the liver processes alcohol at a fixed rate (roughly one standard drink per hour) regardless of physical activity, and a stumbling drunk person is a falling, injuring-themselves drunk person.
Never try to induce more vomiting. The body is already vomiting as a protective reflex against the alcohol in the stomach, and forcing additional episodes increases the risk of tearing the esophageal lining. These tears, called Mallory-Weiss tears, can cause significant bleeding. If you see vomit that looks like dark coffee grounds or contains visible blood, that’s a sign of internal bleeding and requires immediate medical attention.
Why Vomiting While Drunk Is Dangerous
The body triggers vomiting as a defense mechanism when blood alcohol concentration climbs too high, typically in the range of 0.16% to 0.30%. At these levels, a person is already experiencing confusion, memory blackouts, and significant impairment. The problem is that alcohol simultaneously weakens the protective reflexes that keep vomit out of the lungs. The gag reflex and upper-airway reflexes that normally prevent aspiration are dulled, meaning the body is expelling stomach contents while also losing its ability to keep those contents from entering the lungs.
If vomit reaches the lower airways, it can cause aspiration pneumonia, a serious lung infection that develops over the following days. Even a small amount of inhaled stomach acid can damage lung tissue. This is why the recovery position matters so much: gravity does the work that the person’s own reflexes can no longer do reliably.
Once the Vomiting Stops
After the person has stopped vomiting and is alert enough to drink fluids, focus on gentle rehydration. Start with small sips of water. There’s no need to rush. Offering large amounts of fluid to someone whose stomach is still irritated will likely trigger another round of vomiting. A teaspoon every few minutes is a reasonable starting point, gradually increasing as they keep it down.
Electrolyte drinks like Pedialyte or watered-down sports drinks (half water, half sports drink) are better than plain water once they can tolerate more fluid, since vomiting depletes sodium and potassium along with water. Avoid full-strength fruit juice or soda, which can irritate the stomach further. Food can wait until the nausea has clearly passed, and even then, bland options like crackers or toast are the safest bet.
Keep them in the recovery position if they fall asleep, and continue checking on them periodically through the night. Alcohol levels can still be rising if they drank heavily in a short window before vomiting, so someone who seems to be improving can still deteriorate. Set an alarm if you need to, and check that they’re breathing normally and responsive to gentle contact each time.
What the Color of Vomit Can Tell You
Most alcohol-related vomit contains partially digested food and liquid, often with a strong acidic smell. That’s unpleasant but normal. Yellow or green vomit usually means bile, which shows up when the stomach is empty. This is common after multiple rounds of vomiting and isn’t dangerous on its own.
What should concern you is vomit that’s dark brown or looks like coffee grounds. This appearance signals digested blood and can indicate bleeding in the stomach or esophagus. Bright red blood in vomit is also a clear emergency sign. Forceful, repeated vomiting can tear the lining of the esophagus, and these tears sometimes bleed heavily. If you see either of these, call for emergency help right away.
