If you are throwing up after drinking alcohol the next day, start by checking for warning signs rather than looking for a quick hangover cure. Alcohol can irritate your stomach lining, but vomiting after a night out is not always caused by alcohol and is not automatically harmless.
For an adult who is fully awake, able to swallow, and has no warning signs, small sips and rest may help while symptoms settle. If you cannot keep fluids down or you are getting worse, get medical advice. Trouble waking up, abnormal breathing, or a seizure means calling 911.
When Vomiting After Drinking Alcohol Needs Medical Help
Call 911 for possible alcohol poisoning
Drinking too much alcohol too quickly can cause alcohol poisoning. It can be life-threatening. Call 911 if you suspect alcohol poisoning. These warning signs need immediate medical attention, even if the cause is uncertain:
Trouble waking up or staying awake.
Confusion or a seizure.
Slow breathing, irregular breathing, or trouble breathing.
Pale or blue-tinged skin, especially with cold, clammy skin.
Alcohol affects the gag reflex, so someone with alcohol poisoning may choke on vomit. Stay with the person and follow the dispatcher’s directions. If they are awake and vomiting, help them lean forward. If they are lying down or unconscious but breathing, turn them onto their side. Do not try to make them vomit. Do not offer food. Do not give drinks unless the person is fully awake, swallowing safely, and not vomiting. (NIAAA, n.d.-b;NHS, 2026a)
Get emergency care for blood or sudden severe pain
Vomit containing blood or material that looks like coffee grounds needs emergency medical care. So does sudden, severe abdominal pain. Go to an emergency department or call 911 for help; do not drive yourself. These symptoms should not be treated as an ordinary hangover. (MedlinePlus, 2025b;NHS, 2023)
Seek prompt advice for ongoing vomiting or dehydration
See a doctor or contact urgent care promptly if you keep vomiting and cannot retain small sips, are urinating much less than usual, or stay dizzy when you stand. A dry mouth and dark urine can also signal dehydration. Severe abdominal pain also needs prompt medical assessment, even if it did not start suddenly. Do not wait for a set number of hours if symptoms are worsening. (MedlinePlus, 2025b;NHS, 2023;NHS, 2026c)
Seek help for other severe, unusual, or worsening symptoms too; this is not a complete list.
Tell the clinician when vomiting began, how often it happens, what you can keep down, and when you last urinated. Also mention pain, blood, medicines or other substances, when you last drank, and how much alcohol you had. This helps them assess the cause and the care you need. (MedlinePlus, 2025b;NIAAA, n.d.-b)
What to Do for Mild Hangover Symptoms
Consider the steps below only if symptoms are mild, you are fully alert, can swallow safely, and have none of the warning signs above. Do not try to drink during an episode of vomiting. Once it has stopped and you can swallow comfortably, try a small sip. (NHS, 2026a)
Start with small sips
Take small sips of water, then gradually drink more if they stay down. A pharmacist can recommend an oral rehydration solution to replace fluid and salts lost through vomiting. If even small amounts keep coming back up, seek medical advice rather than forcing a large drink. (NHS, 2026c;NHS, 2023)
Rehydration addresses fluid loss. It is not a way to sober up or a proven cure for a hangover. (NIAAA, n.d.-a)
Rest and eat when you feel able
Rest and eat when you feel able. Try small portions of bland foods such as crackers, toast, or rice if they sound manageable. You do not need to force food. Fatty or spicy meals may be harder to tolerate while you feel sick. (MedlinePlus, 2024;NHS, 2023)
Be careful with medicines
Do not assume over-the-counter pain relievers are harmless after consuming alcohol. Alcohol with acetaminophen can harm the liver, while aspirin and ibuprofen can irritate the stomach. Ask a pharmacist or clinician what is appropriate for you instead of adding medicines to a home remedy. (NIAAA, n.d.-a)
Drinking alcohol with opioids or medicines that make you sleepy can increase the risk of overdose. Tell the clinician about sleeping pills, anti-anxiety medicines, and other substances as well as your alcohol consumption. (NIAAA, n.d.-b)
There is no proven fast hangover cure. More alcohol the next morning may prolong symptoms rather than resolve the problem. (NIAAA, n.d.-a)
Alcohol increases stomach acid, which can contribute to an upset stomach. Other contributors to hangover symptoms include disrupted sleep and fluid loss. Vomiting can make dehydration worse. (NIAAA, n.d.-a;NHS, 2026c)
Other causes, such as an infection, food poisoning, medicine side effects, or pregnancy, may explain vomiting even if you drank the night before. Let a clinician know about unusual, repeated, or worsening symptoms rather than assuming alcohol explains everything. (MedlinePlus, 2025b)
Could This Be Alcohol Withdrawal?
Withdrawal is a separate concern for people who drink heavily on a regular basis and then stop or cut down. Vomiting along with shaking, sweating, anxiety, or a racing heart may be withdrawal, not simply a hangover. Contact a clinician right away if you think this could be happening. A seizure, hallucinations, or severe confusion requires emergency care. (MedlinePlus, 2025a;NHS, 2026b)
If you have had withdrawal symptoms before, get medical help before trying to stop drinking on your own. A clinician can assess whether you need monitored treatment. Do not use this article as a home-detox plan. (NHS, 2026b;MedlinePlus, 2025a)
How Long Should Vomiting After Drinking Last?
Hangover symptoms can last 24 hours or longer. That describes a hangover, not a safe period to wait through repeated vomiting. (NIAAA, n.d.-a)
Seek care sooner if you cannot keep fluids down, become dehydrated, or have warning signs. Vomiting that continues beyond 24 hours also needs medical assessment, even without the other signs. How sick you feel and whether you can retain fluids matter more than a countdown. (MedlinePlus, 2025b)
Reducing Alcohol Consumption Safely
Choosing not to drink alcohol avoids an alcohol hangover. If you do drink, less alcohol reduces the risk; the order of alcoholic beverages does not make heavy drinking safe. (NIAAA, n.d.-a)
If cutting down is difficult, support can include counseling, medicines, and help changing drinking habits. The right approach depends on your needs. Anyone with possible dependence or past withdrawal should seek a medical plan before stopping. (NHS, 2026b)
If Drinking Is Repeatedly Making You Sick
You do not need to decide on an addiction label before asking for help. Start with a medical assessment of the vomiting and a candid discussion about your drinking. A clinician can help you understand what is happening and which options fit your situation. (MedlinePlus, 2025b;NHS, 2026b)

Frequently Asked Questions
Does vomiting mean the alcohol is out of my body?
No. Alcohol can remain in the bloodstream, and alcohol absorption can continue after drinking stops. Vomiting is not a reliable sign that someone is sober or safe. Do not try to make yourself or another person vomit. (NIAAA, n.d.-b;NHS, 2026a)
Should I keep drinking water if it comes straight back up?
Do not force large amounts. If you are fully alert and can swallow safely, try small sips between episodes. If you repeatedly cannot keep fluid down, get prompt medical advice rather than continuing home remedies. (NHS, 2026a;NHS, 2023)

Drinking too much alcohol too quickly can cause alcohol poisoning. It can be life-threatening. Call 911 if you suspect alcohol poisoning. These warning signs need immediate medical attention, even if the cause is uncertain:
Do not wait for every symptom or try to judge safety by how many drinks the person had. Never assume someone with possible alcohol poisoning can sleep it off. (National Institute on Alcohol Abuse and Alcoholism [NIAAA], n.d.-b; NHS, 2026a)

Why Drinking Alcohol Can Cause Next-Day Vomiting
Alcohol irritates the lining of the stomach and can damage it. This can contribute to nausea, vomiting, and stomach pain. That does not mean every episode is an ulcer or that the cause can be identified from symptoms alone. (National Institute of Diabetes and Digestive and Kidney Diseases [NIDDK], 2019)
Alcohol increases stomach acid, which can contribute to an upset stomach. Other contributors to hangover symptoms include disrupted sleep and fluid loss. Vomiting can make dehydration worse. (NIAAA, n.d.-a; NHS, 2026c)
Other causes, such as an infection, food poisoning, medicine side effects, or pregnancy, may explain vomiting even if you drank the night before. Let a clinician know about unusual, repeated, or worsening symptoms rather than assuming alcohol explains everything. (MedlinePlus, 2025b)
