Ketamine Therapy for Alcohol Use Disorder

Alcohol use disorder (AUD) affects approximately 29.5 million Americans and is one of the leading causes of preventable death worldwide. Despite available treatments including medications like naltrexone and acamprosate, behavioral therapies, and peer support programs, relapse rates remain high. Emerging research suggests that ketamine, particularly when combined with psychological therapy, may offer a novel approach to reducing alcohol consumption and supporting long-term recovery.

How ketamine may help with alcohol use disorder

  • Memory reconsolidation disruption — research suggests ketamine may interfere with the reconsolidation of maladaptive reward memories associated with alcohol, potentially weakening the powerful cue-triggered cravings that drive relapse
  • Neuroplasticity enhancement — ketamine may promote the formation of new neural connections, supporting the development of healthier behavioral patterns and coping strategies
  • Addressing co-occurring depression — depression and AUD frequently co-occur, and ketamine's rapid antidepressant effects may help address the depressive symptoms that often contribute to alcohol use
  • Enhanced therapeutic engagement — when combined with psychotherapy, ketamine may create a window of increased psychological flexibility that helps patients engage more deeply in therapy

What the research shows

A landmark randomized controlled trial by Grabski et al. (2022), published in the American Journal of Psychiatry, studied 96 participants with severe AUD and found that those who received ketamine combined with psychotherapy had significantly higher abstinence rates at 6-month follow-up compared to those who received placebo with psychotherapy. The ketamine group was 2.7 times more likely to be completely abstinent at the end of the study period. An earlier study by Das et al. (2019), published in Nature Communications, demonstrated that ketamine could weaken alcohol-related memories when combined with a memory reactivation procedure, leading to a significant reduction in drinking days over a 9-month follow-up.

While these results are encouraging, research on ketamine for AUD is still in relatively early stages. Larger, multi-site trials are needed to confirm these findings and establish optimal treatment protocols. Ketamine is not FDA-approved for alcohol use disorder and is used off-label. Importantly, ketamine therapy for AUD should be part of a comprehensive treatment approach that includes psychological support and, where appropriate, coordination with addiction specialists.

Frequently asked questions

Can ketamine help with alcohol addiction?

Preliminary research suggests that ketamine, particularly when combined with psychotherapy, may help reduce alcohol consumption and cravings in people with alcohol use disorder. A notable clinical trial showed that ketamine-assisted therapy led to significantly higher abstinence rates compared to placebo. However, this research is still emerging, and ketamine is not FDA-approved for alcohol use disorder.

How does ketamine help with alcohol cravings?

Researchers believe ketamine may help with alcohol use disorder through multiple mechanisms: it may disrupt maladaptive reward memories associated with alcohol, promote neuroplasticity that supports new behavioral patterns, and address co-occurring depression that often drives alcohol use. Some studies have also explored ketamine's ability to interfere with the reconsolidation of alcohol-related memories.

Is ketamine FDA-approved for alcohol use disorder?

No. Ketamine is FDA-approved only as an anesthetic. Its use for alcohol use disorder is off-label and based on emerging clinical research. Treatment should only be pursued under the supervision of a licensed physician who can evaluate your specific situation, including your alcohol use history and any co-occurring conditions.

Is it safe to use ketamine if I have a history of substance use?

Ketamine is a Schedule III controlled substance with potential for misuse, which requires careful evaluation in patients with substance use histories. Your physician will thoroughly assess your substance use history, current recovery status, and risk factors before determining if ketamine therapy is appropriate. When prescribed and monitored by a physician, the risk of misuse can be managed, but this requires honest communication and close clinical oversight.
