Ketamine Therapy for Alcohol Use Disorder in San Diego: A New Frontier in Addiction Medicine

Alcohol use disorder (AUD) is one of the most common and consequential health conditions in the United States — and one of the hardest to treat. Despite access to FDA-approved medications like naltrexone and acamprosate, most people who attempt sobriety relapse within a year. Ketamine therapy is emerging as a compelling new tool in addiction medicine, with a growing body of research suggesting it may meaningfully reduce relapse rates and extend periods of abstinence in ways that existing treatments cannot.

 

Why Addiction Is So Difficult to Treat

Addiction is not a moral failure — it is a brain disease. Alcohol hijacks the brain’s reward circuitry, weakens prefrontal regulation of impulse control, and creates deeply ingrained behavioral and emotional patterns that are extraordinarily resistant to change. The craving pathways are powerful and are often activated by people, places, emotions, and sensations that the individual has no ability to fully avoid.

Traditional addiction treatment — detoxification, therapy, 12-step programs, and medications — addresses these problems at the behavioral and pharmacological level, but leaves the underlying neurological patterns largely intact. This is a significant reason why relapse rates remain so high even among motivated, well-supported individuals.

 

What Research Shows About Ketamine for Alcohol Use Disorder

Several compelling clinical trials have examined ketamine’s potential for AUD. The most significant is the KARE trial (Ketamine for the Reduction of Alcoholic Relapse), conducted by researchers at University College London and published in the American Journal of Psychiatry. The trial found that patients receiving ketamine infusions in combination with psychological therapy were significantly less likely to relapse to heavy drinking at 6 months compared to those receiving therapy alone — and those effects persisted at 12-month follow-up.

The proposed mechanisms include:

 

Disrupting Maladaptive Memory Reconsolidation

Ketamine interferes with the reconsolidation of reward memories — essentially weakening the powerful associative memories that trigger cravings. When a smell, a location, a feeling, or a social situation reactivates an alcohol-related memory, the urge to drink is a direct result. Ketamine appears to disrupt this recall and reconsolidation process, reducing the grip of those conditioned responses. This is a fundamentally different approach from simply blocking the pleasure of alcohol, as naltrexone does.

 

Promoting Neuroplasticity

Ketamine stimulates BDNF (brain-derived neurotrophic factor) and promotes the rapid formation of new synaptic connections — creating a window of opportunity during which new, healthier behavioral and emotional patterns are more easily established. This is why pairing ketamine with meaningful therapeutic work during and after treatment significantly extends its benefits.

 

Treating Co-Occurring Depression

Depression is a powerful driver of relapse for people with AUD — alcohol is one of the most commonly self-medicated mood disorders in existence. Because ketamine is one of the fastest and most effective treatments for depression available, addressing this co-occurring condition directly and rapidly may remove one of the most significant triggers for return to drinking.

 

How We Approach Addiction at Seaside Ketamine

Ketamine for alcohol use disorder is not a standalone cure, and we don’t present it as one. At Seaside Ketamine, it is used as part of a comprehensive approach that includes:

• Medical evaluation and safety screening
• A structured series of IV ketamine infusions
• Integration sessions to process experiences and embed new patterns
• Coordination with your broader support system (therapist, primary care, sponsor, or family) as appropriate

An important note on detox: We do not offer outpatient detoxification services. Patients who are physiologically dependent on alcohol — at risk for alcohol withdrawal seizures — must complete a medically supervised detox before beginning ketamine treatment. We can help coordinate this referral and will have you assessed appropriately before beginning any treatment.

 

Is Ketamine Right for You If You’re Struggling with Alcohol?

Ketamine for AUD is most appropriate for patients who:

• Have already completed a supervised detox or are not physiologically dependent
• Have a genuine desire to reduce or stop drinking
• Have not responded adequately to standard treatments (therapy, naltrexone, acamprosate, or similar)
• Do not have severe active liver disease or other absolute medical contraindications

The consultation with Dr. Gillin will assess all of these factors honestly and without judgment. If ketamine isn’t the right fit for your situation, we’ll tell you — and help you understand what might be.
