Alcohol addiction affects millions of people and continues to grow each year. Many people try to stop drinking on their own but quickly realize how difficult the process can be. When alcohol use becomes a daily habit, the body depends on it to function. Removing it suddenly creates strong physical and emotional reactions that can feel frightening without support.

Alcohol detox is the first important step toward healing. It helps the body clear alcohol safely while managing withdrawal symptoms that may appear within hours. A proper detox gives the brain time to rebalance and prepares each person for deeper recovery work. Understanding how detox works can make the process less stressful and much safer.

Key Takeaways

  • Alcohol detox removes alcohol from the body and helps stabilize physical health.
  • Withdrawal symptoms can range from mild discomfort to serious medical complications.
  • Symptoms often begin within the first few hours after the last drink.
  • Some people may develop hallucinations, seizures, or delirium tremens during detox.
  • Medical supervision keeps detox safe and reduces the risk of complications.
  • Medications like benzodiazepines, naltrexone, and acamprosate may help manage symptoms.
  • Detox is only the first step in recovery and must be followed by therapy and aftercare.
  • Some people experience post-acute withdrawal symptoms for weeks or months after detox.

Alcohol is a central nervous system depressant that the body begins to rely on over months of persistent alcohol use disorder. As this happens, the brain of such individuals eventually stops synthesizing certain chemicals as it receives them from alcohol. As a result, they end up becoming dependent on this beverage. In such circumstances, quitting alcohol triggers an unusual body response that requires time to overcome completely. This time period is usually accompanied by severe symptoms, known as withdrawal symptoms which may include several minor and major symptoms. Some common minor alcohol detox symptoms include: (source: MedlinePlus, n.d.)

  • Sweating
  • Anxiety
  • Headaches
  • Insomnia
  • Nausea

As the process of alcohol detoxification progresses, some people develop more severe side effects, such as:

  • Tremors
  • Disorientation
  • Extreme hallucinations
  • Seizures
  • Delirium tremens

Due to the severity of specific alcohol withdrawal symptoms, treatment professionals say it is essential to undergo alcohol detox under professional supervision. This is particularly true for people with a history of medical conditions, such as heart or lung disease, as these symptoms can quickly worsen and may turn life-threatening. A treatment specialist can track such individuals’ heart rates and blood pressure to ensure that their condition is not worsening.

Withdrawal symptoms associated with alcohol detox can surface as early as within two hours of the last drink. While the most painful of these symptoms usually subside within the first seven days, a few milder ones linger for a few weeks, months, or even a whole year. Unfortunately, experts do not have an exact timeline for alcohol withdrawal; however, a general outline regarding what to expect is mentioned below. (source: SAMHSA, n.d.)

First Six to Twelve Hours

During the first twelve hours, the initial symptoms of an alcohol detox begin to surface. These are mild in severity but can quickly start worsening as time goes on. Some of these mild symptoms include headaches, nausea, shakiness, anxiety, and irritability.

Day One

By the end of the first 24 hours, the symptoms of alcohol dependence and withdrawal may have become increasingly severe. Apart from the symptoms felt during the first 12 hours, some additional symptoms, like disorientation, seizures, and hand tremors may appear.

Day Two

The most painful symptoms from the first day of alcohol detox continue into day two. Some people may experience panic attacks and hallucinations during this time as the body continues to rid itself of alcohol. (source: NHS, n.d.)

Days Three To Seven

For the remainder of the week in detox, different symptoms are likely to come and go. Day three to seven is a critical period where alcohol detox occurs when an individual is at the highest risk of developing life-threatening symptoms, like delirium tremens.

After One Week

By the time an individual is done with the first week of alcohol detox, most of their withdrawal symptoms will begin to taper off. Some may linger on for a few more weeks, but most are minor and treatable with medication.

Keep in mind that even after the most severe acute withdrawal symptoms have subsided, some people still experience post-acute withdrawal syndrome (PAWS). PAWS refers to the prolongation of the detox symptoms and may include issues like low energy, anxiety, delayed reflexes, and trouble sleeping. These issues may last from several months up to a year. (source: NIAAA, n.d. (treatment))

Most alcohol detox programs take place in an inpatient rehab facility where experts may use different medications to control uncomfortable withdrawal symptoms. These medications also balance an individual’s body chemicals while lowering the risk of developing severe complications. A medical professional administers these medications in controlled doses and monitors their side effects within a rehab. If the medication interferes with the detox process or causes unwanted side effects, it can be immediately withdrawn or replaced with a safer alternative.

Some common medications used to manage alcohol detox side effects include the following:

Benzodiazepines

Benzodiazepines are commonly used to treat alcohol withdrawal syndrome and drugs related to alcohol detox. These medications work by calming the central nervous system while treating other related issues, like muscle spasms, anxiety, and insomnia. Benzodiazepines come in two forms: long-acting and short-acting. Experts generally prefer long-acting benzodiazepines as they work longer and require fewer re-administrations. Some common examples of benzodiazepines include diazepam (Valium) and chlordiazepoxide (Librium). (source: NICE, 2010)

Naltrexone

Naltrexone helps with alcohol detox by reducing alcohol cravings. In the event of a relapse, this medication also reduces the high feeling triggered by alcohol. Since it can also stimulate withdrawal symptoms in many cases, most experts wait for at least 7 to 10 days before prescribing naltrexone. The medication is available as an injectable (Vivitrol) and a tablet (Depade or ReVia).

Disulfiram

Disulfiram is another medication commonly prescribed to people undergoing an an alcohol detox process. Unlike other medications, disulfiram triggers severe reactions in someone who consumes alcohol during detox. For instance, if someone drinks while using disulfiram, they may develop facial flushing along with weakness, headache, nausea, and low blood pressure. These adverse effects deter them from continuing their drinking pattern.

Acamprosate

Acamprosate is particularly beneficial for people who have been drinking for years. This medication, sold under the name Campral, helps the brain restore its normal functioning once someone quits drinking. Research has revealed that this medication also helps manage alcohol cravings; however, it does not act as a deterrent quit drinking or produce any unwanted effects in people who consume alcohol. (source: Cleveland Clinic, n.d.)

Nutritional Support Medicines

Sometimes, a detox expert may administer certain nutrients, like thiamine, folic acid, and magnesium, to decrease the severity of withdrawal symptoms and correct any nutrient deficiencies that alcohol may have caused.

Once you have successfully gone through all alcohol detox stages and completed the process, it is imperative to keep the recovery process going by seeking help from a rehabilitation program. The following are some important components of a good alcohol addiction treatment and rehabilitation program:

Therapy

Therapies, such as cognitive behavioral therapy (CBT) and dialectical behavioral therapy (DBT), can help recovering alcoholics recognize and address all underlying causes of their addiction. Following detox, many people are at risk of relapsing, especially if the triggers that may lead them to drink again are not managed properly. These triggers include reminders of previous traumas or any stressful life events. Therapy can help people understand and deal with these triggers and other issues that may have led to alcoholism in the first place. It also equips them with skills and tools that they can keep applying in the future to prevent relapses. (source: StatPearls, n.d.)

Aftercare

Recovery from alcohol addiction is a lifelong struggle, and aftercare programs are there to support individuals to maintain it after their initial course of treatment is finished. These aftercare services connect them with a support network comprising empathetic people and support groups that help them maintain abstinence in the long run. It also includes secondary care that allows such people to ease back into normality after completing alcohol detox and rehabilitation.

Whether or not they are combining alcohol with other drugs
Whether or not they have a family history of alcohol or substance abuse.
Whether or not they have experienced alcohol withdrawal before
Why do alcohol withdrawal symptoms occur?
When an individual uses alcohol over a long time, their brain chemistry changes. Since alcohol acts as a depressant, the body responds to its presence by releasing higher levels of stimulating chemicals, such as dopamine and gamma-aminobutyric acid (GABA). The release of these stimulating neurotransmitters causes temporary restoration of the chemical homeostasis in the brain. However, as the individual continues to drink, the body develops a tolerance to alcohol. What this means is that they require increasingly higher quantities of alcohol to experience the same feeling of intoxication. At the same time, the brain keeps producing more and more amounts of stimulating neurotransmitters to keep up with the increased intake of alcohol. As this cycle continues for weeks, the user’s biochemistry becomes imbalanced. In such circumstances, when a person suddenly stops using alcohol, their brain is not fully registered with this cessation. Consequently, the brain continues to produce the neurotransmitters that overflow in the body and lead to withdrawal symptoms.
