For some people, stopping alcohol suddenly is not just uncomfortable, it can be dangerous. This guide summarizes the MedlinePlus Medical Encyclopedia article on alcohol withdrawal from the U.S. National Library of Medicine. It is general education, not medical advice, and it covers alcohol only.

MedlinePlus says to “Go to the emergency room or call 911 or the local emergency number if seizures, fever, severe confusion, hallucinations, or irregular heartbeats occur.”
If someone is in immediate physical danger, call 911. If you or someone you know is in emotional distress or a suicide crisis, call or text 988. SAMHSA says “911 is the primary contact for emergencies involving medical emergencies, fire, crimes in progress, or other situations requiring immediate physical intervention” and that “988 is for emotional and behavioral health support with minimal law enforcement involvement unless there is an immediate physical safety threat.”
MedlinePlus says “Alcohol withdrawal is a serious condition that may quickly become life-threatening.” It describes withdrawal as symptoms that may occur when a person who has been drinking too much alcohol on a regular basis suddenly stops. It says the more often you drink, the more likely you are to have symptoms when you stop, and that certain other medical problems can make symptoms more severe. It also says withdrawal may range from a mild and uncomfortable disorder to a serious, life-threatening condition, and that death is possible, especially if delirium tremens occurs.
MedlinePlus says symptoms tend to begin within 8 hours after the last drink but can occur days later, tend to peak by 24 to 72 hours, and may go on for weeks. Common symptoms it lists include anxiety or nervousness, depression, fatigue, irritability, jumpiness or shakiness, mood swings, nightmares and not thinking clearly. Other signs include sweating and clammy skin, headache, insomnia, loss of appetite, nausea and vomiting, a rapid heart rate and tremor of the hands or other body parts.
It describes delirium tremens as a severe form of withdrawal that can cause agitation, sudden severe confusion, fever, seeing or feeling things that are not there, and seizures.
MedlinePlus says people with moderate-to-severe symptoms may need treatment at a hospital or other facility that treats alcohol withdrawal, where they are watched closely for hallucinations and other signs of delirium tremens. It says care may include monitoring blood pressure, temperature, heart rate and blood chemistry, fluids or medicines through a vein, and sedatives until withdrawal is complete.
For mild-to-moderate symptoms, it says treatment can often happen in an outpatient setting. In that case, it says you will need someone to stay with you and keep an eye on you, and you will likely need daily visits to your provider until you are stable.
MedlinePlus says to contact your provider right away or go to the emergency room if you think you might be in alcohol withdrawal, especially if you were using alcohol often and recently stopped. If you go to the hospital for another reason, it says to tell the providers if you have been drinking heavily so they can monitor you for withdrawal symptoms.
