Is It a Hangover or Alcohol Poisoning?
If someone is confused, can't stay awake, is vomiting, has a seizure, or breathes slowly, it may be alcohol poisoning. Call 911 right away.
The simple answer
A hangover is the morning after. Alcohol poisoning can happen when there's so much alcohol in the blood that breathing and other basic functions start to shut down. If someone shows danger signs, call 911. Don't wait for every sign. Stay with the person, and don't let them 'sleep it off.'
Myth vs Fact
A cold shower, coffee or a walk will bring them around.
NIH says these do not reverse alcohol overdose and can make things worse. Call 911.
The science
- NIHAlcohol overdose happens when parts of the brain that control breathing, heart rate and body temperature begin to shut down.
- NIHSigns: confusion, trouble staying awake, vomiting, seizures, slow breathing (fewer than 8 breaths a minute), irregular breathing (10 seconds or more between breaths), slow heart rate, clammy skin, no gag reflex, and very low body temperature.
- NIHBlood alcohol can keep rising even after someone stops drinking or passes out.
- NIHA person who has passed out can choke on their vomit.
- NIHMixing alcohol with opioids, sleep medicines, anti-anxiety medicines or even some antihistamines raises the risk of overdose.
- NIHWhile you wait for help: don't leave them alone; keep them sitting or partly upright on the ground, not in a chair; if they're vomiting, help them lean forward; if they're passed out or lying down, roll them onto their side.
