From the Guidelines
Alcohol withdrawal typically occurs over a period of 6-24 hours after the last drink, with symptoms peaking at 24-72 hours and resolving within 1-7 days. The timeline varies based on the individual's drinking history and overall health. Mild symptoms like anxiety, tremors, and insomnia usually appear first, followed by more severe symptoms such as elevated blood pressure, increased heart rate, and fever during the peak period 1. In severe cases, withdrawal seizures may occur 24-48 hours after cessation, while delirium tremens (DTs), the most dangerous manifestation, typically develops 48-72 hours after stopping alcohol and can last 2-3 days.
Symptoms and Treatment
- Symptoms of alcohol withdrawal syndrome (AWS) include increased blood pressure and pulse rate, tremors, hyperreflexia, irritability, anxiety, headache, nausea, and vomiting 1.
- Benzodiazepines, such as diazepam and lorazepam, are considered the 'gold standard' treatment for AWS, given their efficacy in reducing both withdrawal symptoms and the risk of seizures and/or delirium tremens 1.
- Thiamine (100mg daily) is also essential to prevent Wernicke's encephalopathy.
- The Clinical Institute Withdrawal Assessment for Alcohol (CIWA-Ar) is useful in clinical practice to assess the severity of AWS, with a score >8 indicating a moderate AWS and a score ≥15 indicating severe AWS 1.
Management and Prevention
- Pharmacological treatment is recommended for both moderate and severe AWS using a symptom-triggered regimen rather than a fixed dose schedule to prevent the accumulation of the drug 1.
- Long-acting benzodiazepines (e.g. diazepam, chlordiazepoxide) provide more protection against seizures and delirium, but short and intermediate-acting benzodiazepines (e.g. lorazepam, oxazepam) are safer in elderly patients and those with hepatic dysfunction 1.
- Clinicians should avoid the use of benzodiazepines beyond the initial 10-14 days of treatment due to the potential risk of abuse 1.
From the Research
Time Frame for Alcohol Withdrawal
The typical time frame for alcohol withdrawal can vary depending on several factors, including the severity of the withdrawal and the individual's overall health.
- Symptoms of alcohol withdrawal typically begin within 6 to 24 hours after the last drink, and can last for several days to a week or more 2, 3.
- Mild to moderate withdrawal symptoms usually resolve within 5 to 7 days, but more severe symptoms can last longer 4, 5.
- In some cases, withdrawal symptoms can persist for several weeks or even months, a condition known as post-acute withdrawal syndrome (PAWS) 3.
Factors Influencing Withdrawal Time Frame
Several factors can influence the time frame for alcohol withdrawal, including:
- Severity of alcohol dependence: Individuals with more severe dependence may experience longer and more intense withdrawal symptoms 4, 2.
- History of previous withdrawals: Individuals who have experienced previous withdrawals may be at risk for more severe symptoms and a longer withdrawal time frame 4, 5.
- Presence of co-occurring medical or psychiatric conditions: Individuals with underlying medical or psychiatric conditions may be at risk for more severe withdrawal symptoms and a longer withdrawal time frame 3, 6.
Treatment and Management
Treatment and management of alcohol withdrawal typically involve a combination of medications, such as benzodiazepines, and supportive care, such as hydration and nutrition 4, 2, 5.
