Gabapentin and Alcohol Withdrawal: Efficacy and Comparisons
Introduction to Gabapentin in Alcohol Withdrawal Treatment
Gabapentin, an anticonvulsant medication, has been increasingly studied for its potential benefits in treating alcohol withdrawal syndrome (AWS) and alcohol use disorder (AUD). This article synthesizes findings from multiple studies to evaluate the efficacy of gabapentin in managing alcohol withdrawal symptoms and reducing alcohol consumption.
Efficacy of Gabapentin in Alcohol Withdrawal Syndrome
Several studies have demonstrated that gabapentin is effective in reducing the symptoms of alcohol withdrawal. A randomized clinical trial found that gabapentin significantly reduced the severity of alcohol withdrawal symptoms compared to lorazepam, a commonly used benzodiazepine, particularly at higher doses (1200 mg) 2. Another study comparing gabapentin with phenobarbital found no significant differences in treatment outcomes, suggesting that gabapentin is as effective as phenobarbital in managing AWS 3.
Gabapentin vs. Benzodiazepines
Gabapentin has been compared to benzodiazepines in multiple studies. One study found that gabapentin was as effective as CIWA-directed benzodiazepines in treating hospitalized patients with mild to moderate AWS, with similar outcomes in terms of length of stay and secondary measures such as seizures and delirium tremens 6. Another study highlighted that gabapentin reduced the need for benzodiazepines and was associated with fewer cravings and better sleep quality during early sobriety 10.
Gabapentin's Role in Reducing Alcohol Consumption and Craving
Gabapentin has also shown promise in reducing alcohol consumption and craving. A double-blind, placebo-controlled trial demonstrated that gabapentin significantly reduced the number of drinks per day, the percentage of heavy drinking days, and increased the percentage of days of abstinence compared to placebo 4. Additionally, gabapentin combined with naltrexone was found to improve drinking outcomes during the early cessation phase, although these benefits did not persist after gabapentin was discontinued 7.
Safety and Tolerability of Gabapentin
Gabapentin is generally well-tolerated, with a favorable safety profile. Common side effects include dizziness, but these do not significantly impact its efficacy 1. A review of the literature indicated that gabapentin is safe for use in managing mild alcohol withdrawal and can positively influence sleep and mood-related outcomes, which may contribute to long-term benefits in treating alcohol dependence 5.
Conclusion
Gabapentin appears to be a promising alternative to traditional benzodiazepines for the treatment of alcohol withdrawal syndrome and alcohol use disorder. It effectively reduces withdrawal symptoms, decreases alcohol consumption, and minimizes cravings, with a favorable safety profile. Future studies should focus on optimizing dosing strategies and further validating these findings to establish gabapentin as a standard treatment option for AWS and AUD.

Systematic ReviewHighly CitedUse of Gabapentin for Alcohol Withdrawal Syndrome in the Hospital Setting: A Randomized Open-Label Controlled Trial
Fixed-dose gabapentin taper showed similar outcomes to CIWA-directed benzodiazepines for treating hospitalized patients with mild/moderate alcohol withdrawal syndrome, but the results are limited due to under-enrollment and pre-enrollment benzodiazepine use.
