What is the recommended treatment for alcohol dependence?

Treatment of Alcohol Dependence

For alcohol dependence, implement a comprehensive treatment strategy combining pharmacotherapy (acamprosate, naltrexone, or disulfiram), psychosocial interventions including cognitive behavioral therapy, and active engagement with Alcoholics Anonymous, with benzodiazepines as first-line treatment for acute withdrawal management. 1

Acute Withdrawal Management

Benzodiazepines are the front-line medication for managing alcohol withdrawal, alleviating discomfort and preventing seizures and delirium. 2, 1

• Antipsychotic medications should never be used as stand-alone treatment for withdrawal—only as adjunct therapy to benzodiazepines in severe delirium that hasn't responded to adequate benzodiazepine doses. 2
• All patients undergoing withdrawal must receive oral thiamine; those at high risk (malnourished, severe withdrawal) or with suspected Wernicke's encephalopathy require parenteral thiamine. 2
• Patients at risk of severe withdrawal, those with concurrent serious physical or psychiatric disorders, or those lacking adequate support should be managed in an inpatient setting. 2, 1
• Anticonvulsants should not be used following an alcohol withdrawal seizure for prevention of further seizures. 2

Pharmacotherapy for Relapse Prevention

First-Line Medication Options

Acamprosate is the only medication with sufficient high-quality evidence demonstrating superiority over placebo for maintaining alcohol abstinence in primary care settings. 1 The choice among acamprosate, disulfiram, or naltrexone should consider patient preferences, motivation, and availability. 2

Naltrexone Dosing and Administration

• Standard dose is 50 mg once daily, which has been proven effective in 12-week placebo-controlled trials. 3
• Naltrexone reduces relapse to heavy drinking and drinking frequency but does not substantially enhance complete abstinence. 4, 5
• Critical contraindication: Never use naltrexone in patients with alcoholic liver disease due to hepatotoxicity risk. 1
• Patients must be completely opioid-free (including tramadol) for a minimum of 7-10 days before starting naltrexone to avoid precipitated withdrawal. 3
• Alternative dosing schedules for supervised administration include 50 mg every weekday with 100 mg on Saturday, 100 mg every other day, or 150 mg every third day. 3

Acamprosate

• Acamprosate reduces drinking frequency and is effective at maintaining abstinence in alcohol-dependent patients following withdrawal. 4, 5
• European studies show better results than U.S. studies, with modest efficacy particularly in recently abstinent patients. 5

Disulfiram

• Evidence for disulfiram is mixed—some studies show reduced drinking frequency but minimal evidence for improved continuous abstinence rates. 2, 4
• Targeted studies on supervised administration may be warranted. 4

Psychosocial Interventions

Brief Interventions (First-Line for Hazardous Drinkers)

• Implement the FRAMES model as first-line approach for hazardous drinkers and those with mild alcohol use disorder, delivered in 5-30 minutes incorporating individualized feedback and advice on reducing or stopping consumption. 1
• Brief interventions are effective at reducing morbidity and mortality related to drinking. 1

Cognitive Behavioral Therapy

• CBT should be implemented to help patients develop coping skills and address psychological patterns underlying drinking behavior. 1
• The combination of naltrexone with CBT is superior to other combinations—fewer CBT-naltrexone patients relapsed, and those who did had fewer and more time between subsequent relapses. 6
• Naltrexone combined with CBT resulted in 27% of patients having no relapses to heavy drinking throughout 32 weeks, compared with only 3% receiving placebo with CBT. 7
• CBT and naltrexone share common mechanisms (craving reduction and relapse prevention), making them well-suited for combination use. 6

Alcoholics Anonymous and Mutual Help Groups

• Healthcare providers should actively encourage engagement with Alcoholics Anonymous as it is highly effective in treating alcohol use disorder and should be routinely recommended as part of comprehensive treatment. 1, 8
• Providers should familiarize themselves with locally available AA groups and monitor the impact of attendance on patient recovery. 2, 8
• Family members should also be encouraged to engage with appropriate mutual help groups for families. 2, 8
• Critical pitfall: AA attendance alone may not be sufficient for patients with severe alcohol dependence or significant psychiatric comorbidities who require more intensive professional treatment. 1, 8

Monitoring and Follow-Up

• Regular follow-up appointments every 1-3 months are recommended to assess progress and adjust treatment. 1
• Continued engagement with treatment is essential even after achieving initial abstinence, as relapse rates can reach 50% at one year. 1
• Psychoactive medications used for withdrawal should be dispensed in small quantities or each dose supervised to reduce misuse risk. 2

Common Adverse Effects and Management

• Most patients tolerate naltrexone well; nausea is the most common side effect leading to discontinuation. 3
• A small fraction of patients may experience an opioid withdrawal-like symptom complex (tearfulness, mild nausea, abdominal cramps, restlessness, bone/joint pain, myalgia, nasal symptoms), which may represent unmasking of occult opioid use. 3
• Depression, suicidal ideation, and suicidal attempts have been reported in all treatment groups for alcoholism. 3
