Alcohol Withdrawal Symptoms, Timeline, and Detox Treatment

4 min read · 12 sections

The National Dietary Guidelines recommends a cautious approach to alcohol consumption, with women limiting themselves to 1 drink daily (7 per week) and 2 drinks daily for men (14 per week). Consuming more than this level of alcohol increases a person’s risk of liver disease, cardiovascular disease and other injuries. Even drinking within the recommended limits or at lower levels may increase a person’s cancer risk and can increase their risk of physiological dependence.1

This article will introduce problematic patterns of alcohol consumption in the United States and the risks of developing an alcohol use disorder (AUD), the clinical term for alcohol addiction. It will also explore what happens to your brain and body when you are dependent on alcohol and suddenly stop drinking or reduce your alcohol intake—including symptoms of alcohol withdrawal, the approximate timeline for alcohol detox symptoms, delirium tremens (DTs), how withdrawal can affect your mental health, and what to expect from treatment for alcohol withdrawal.

What is Alcohol Withdrawal Syndrome (AWS)?

Alcohol withdrawal syndrome is a set of symptoms that occur when someone who is physically dependent upon alcohol suddenly stops drinking or drastically reduces their alcohol intake.

Alcohol Withdrawal Symptoms

Signs and symptoms of the various stages of alcohol withdrawal may include:

  • Headaches.
  • Anxiety.
  • Tremors or shakes.
  • Insomnia.
  • Fatigue.
  • Mood changes.
  • Gastrointestinal disturbances.
  • Heart palpitations.
  • Increased blood pressure or heart rate.
  • Hyperthermia.
  • Rapid abnormal breathing.
  • Hallucinations.
  • Seizures.

Alcohol Misuse

Alcohol abuse in America

Misuse of alcohol refers to alcohol use that places you at risk for experiencing physical health problems, mental health issues, and social problems.

Having more than 1 drink daily for women (7 per week) or 2 drinks daily for men (14 per week) is generally considered alcohol misuse.2 Binge drinking, a form of alcohol misuse, is when a man has 5 or more drinks or a woman has 4 or more drinks within a short period of time.2,3

Binge drinking or alcohol misuse can increase someone’s risk of developing an alcohol use disorder (AUD).4 An AUD is a disease characterized by the inability to control alcohol use despite negative, harmful consequences. Craving alcohol, having a tolerance to the effects of alcohol, and experiencing withdrawal symptoms when you try to stop drinking are but some of the criteria that point toward having an AUD.2,4 When a person has a physiological dependence on alcohol, the withdrawal symptoms that are experienced after they significantly reduce or stop drinking can be extremely distressing and uncomfortable, and people commonly return to drinking alcohol as a way of relieving their discomfort.4

Causes of Alcohol Withdrawal

Alcohol withdrawal is thought to arise as a function of various changes in brain activity caused by prolonged and excessive alcohol use. Though the neurochemical details of alcohol withdrawal syndrome are somewhat complicated, its associated symptoms reflect a compensation for previous disruptions in both excitatory and inhibitory neurotransmitter activity—the balance between the two having been upended to begin with as a result of prolonged alcohol use.5

The effects alcohol has on the body are complex, but two particular neurochemicals contribute to both short-term effects of drinking as well as the development of alcohol withdrawal syndrome when someone stops drinking: the brain’s main inhibitory chemical, gamma aminobutyric acid (GABA) and the brain’s main excitatory chemical, glutamate.6 When a person drinks alcohol, it changes the functioning of GABA receptors as well as certain glutamate receptors, resulting in a slowdown of brain functioning that a person typically experiences as decreased anxiety and sedation. The brain reacts by decreasing the amount of GABA being released and increasing glutamate signaling to compensate for how alcohol alters these levels.6 This adaptation functions as long as you continue to drink alcohol—this is known as “tolerance.”

If you stop or significantly reduce alcohol intake, it disrupts your brain activity, causing a hyper-aroused state, which leads to a range of withdrawal symptoms that can appear within hours after your last drink.4,7 The withdrawal symptoms a person experiences, as well as the severity of each, may vary greatly from one person to the next, and it has been estimated that more than 80% of those with an alcohol use disorder may experience withdrawal symptoms.4

When To Seek Help

Generally, you may need treatment for alcohol misuse when you can no longer control the amount you drink or how long you drink. You may also know that you need help with alcohol misuse when you begin experiencing consequences directly related to your alcohol misuse—but you still can’t stop or cut back on the amount that you’re drinking.

Alcohol Withdrawal Stages and Severity

What happens to your body when you give up alcohol hinges on a variety of factors. Depending on the level of physiological alcohol dependence, the severity of acute alcohol withdrawal varies for different individuals.3,8

The American Academy of Family Physicians outlines 3 potential stages that a person in withdrawal may experience. These include:9

  • Stage 1 (mild): Symptoms may include headache, insomnia, anxiety, hand tremors, gastrointestinal disturbances, and heart palpitations.
  • Stage 2 (moderate): Symptoms may include Stage 1 mild symptoms in addition to increased blood pressure or heart rate, confusion, mild hyperthermia, and rapid abnormal breathing.
  • Stage 3 (severe): Symptoms include Stage 2 moderate symptoms in addition to visual or auditory hallucinations, seizures, disorientation, and impaired attention.

Alcohol Withdrawal Timeline

Without treatment by a healthcare professional, some people can progress from Stage 2 to Stage 3 rapidly.8

While a precise timeline for alcohol withdrawal varies from person to person based on several factors (average quantity and duration of heavy drinking behavior, the concurrent presence of physical and mental health issues, etc.), a general symptom timeline for alcohol detox may look something like this:7,9

  • 6-12 hours after the last drink, the relatively mild symptoms of early withdrawal may begin, including headache, mild anxiety, insomnia, small tremors, and stomach upset.
  • By 24 hours, some people may begin to experience visual, auditory, or tactile hallucinations.
  • Within 24-72 hours, various symptoms may have peaked and begun to level off or resolve (though some more protracted symptoms may stick around for weeks or longer). Seizure risks may be highest from 24 to 48 hours after the last drink, requiring close monitoring and seizure prophylaxis. Withdrawal delirium (i.e., DTs) may appear from 48 to 72 hours after the last drink.

Though rare, some individuals experience more persistent withdrawal related symptoms—such as sleep disturbances, fatigue, and changes in mood—that can last for months.9 It is important to note, however, that most people recover fully with proper medical detox and withdrawal management services.11

Alcohol Withdrawal Detox Treatment

Detox is often considered the first stage of treatment.9 It will help you navigate the difficult process of alcohol withdrawal, but it doesn’t address patterns of thought and behavior that contribute to alcohol use.6,11 Various treatment approaches and settings can help provide the ongoing support necessary to maintain long-term sobriety after you complete detox.5,9

  • Inpatient or residential treatment involves living at a facility for the duration of treatment while you receive around-the-clock support and intensive therapy in group and individual sessions.
  • Outpatient treatment involves living at home or in a sober living environment and attending group and individual therapy sessions at regularly scheduled appointments. This allows you to practice what you learn in treatment in real-world situations while managing stressors.

In general, the course of alcohol withdrawal is highly variable and somewhat unpredictable. Screening and assessment tools do not allow physicians to predict with confidence who will or will not experience life-threatening symptoms. Those experiencing mild alcohol withdrawal symptoms or who are concerned about experiencing withdrawal symptoms will benefit from the advice of a physician or clinician trained to assess and treat patients in alcohol withdrawal.

Those experiencing moderate to severe symptoms of alcohol withdrawal, or those who are at risk of experiencing moderate to severe symptoms (i.e., if you’ve had severe alcohol withdrawal symptoms in the past) typically require inpatient monitoring and treatment of withdrawal symptoms at an acute care hospital or detox-equipped facility. Outpatient treatment may be available for mild-to-moderate symptoms of alcohol withdrawal, however, should symptoms become severe, inpatient care may be required.

Medication for Alcohol Withdrawal

To prevent or lessen withdrawal symptoms or medical complications that can occur with severe alcohol withdrawal, doctors may prescribe benzodiazepines. These drugs can stop certain withdrawal reactions from proceeding to serious consequences.8

Other medications may also be used to stabilize patients or for supportive care (e.g., anticonvulsants, antipsychotics, beta blockers and alpha-adrenergic agonists.) Patients who are dehydrated or malnourished may be given fluids or certain vitamins.8

Medications that may be used in the treatment of AUDs may include:

  • Acamprosate, which helps you avoid alcohol use after recovery.
  • Disulfiram, which causes unpleasant symptoms if alcohol is consumed.
  • Naltrexone, which helps to block the rewarding or reinforcing effects of alcohol.

Some of these medications may be prescribed after abstinence or detox.

How Much Do I Have to Drink to Get Withdrawals?

It is impossible to accurately predict who will experience alcohol withdrawal, what the course of withdrawal may be, or the severity of withdrawal. Whether or not you develop alcohol withdrawal symptoms depends heavily on your body chemistry, the amount of alcohol you drink daily, how old you are, whether you have any other co-occurring physical or mental health conditions, and many other factors.8
