Timeline For Alcohol Detox And Withdrawal

Alcohol withdrawal is a condition that develops exclusively in people who’ve become physically dependent on alcohol. This can set in very quickly after a person’s last drink.

Stage 1: First Six To 12 Hours

Individuals who are alcohol-dependent may begin to experience withdrawal symptoms from the lack of alcohol within six to 12 hours after their last drink.

Early signs of alcohol withdrawal may include:

  • headache
  • tremors
  • anxiety
  • upset stomach
  • difficulty sleeping

Stage 2: 12 to 48 Hours

Moderate symptoms, including those physical and psychological, can begin to appear within the first 24 to 48 hours of beginning alcohol detox.

Detox symptoms during this stage might include:

  • agitation
  • disorientation
  • jumpiness
  • mood swings
  • increased body temperature
  • sweating
  • fast breathing
  • high blood pressure
  • pounding heart
  • nightmares
  • not thinking clearly

Severe symptoms of withdrawal, including hallucinations and seizures, can also develop during this time in people with very severe alcohol dependence.

Stage 3: Up to 72 Hours

Alcohol withdrawal symptoms reach peak intensity about 72 hours, or three days, into alcohol detox. Significant physical discomfort, cravings, and anxiety may occur.

Stage 4: Days 3 to 5

After reaching their peak, symptoms generally begin to decline after the first few days of detox. Some symptoms, including lingering effects on mood and sleep, may continue for weeks.

Protracted Withdrawal After Alcohol Detox

People who have been drinking heavily for a long time, or who have developed a severe alcohol addiction, may experience long-lasting side effects of withdrawal.

This condition, known as protracted withdrawal or post-acute withdrawal syndrome (PAWS), can cause symptoms such as depression, anxiety, and insomnia that last weeks or months after your last drink.

What Factors Can Affect The Alcohol Withdrawal Timeline?

A wide range of factors regarding alcohol consumption, overall health, and genetics can affect the amount of time it takes for a person to fully detox from alcohol.

Factors that can affect the alcohol detox timeline include:

  • how much a person drinks
  • how long they’ve been drinking
  • use of other drugs (e.g. opioids, benzodiazepines)
  • co-occurring mental health conditions
  • impaired liver function
  • overall health status
  • history of previous detox attempts
  • genetic factors

Additional factors such as age, weight, metabolism, and body fat can also play a role in how severe withdrawal symptoms become and for how long they last.
