If you live with both depression and a drinking problem, a dual diagnosis, you have probably heard two pieces of advice that cancel each other out. The rehab program says it cannot touch your antidepressants until you are sober. The psychiatrist says get the drinking under control first, then we will talk about your mood. So you wait in the gap between them, and nothing gets better.
This guide is about a different path. Ketamine for dual diagnosis addresses the mood disorder and the substance use disorder as one problem in one brain, at the same time, under medical supervision. At Nushama’s Midtown Manhattan clinic on Madison Avenue, that is how we approach dual diagnosis care. If you have felt caught between fragmented systems, the idea of ketamine for depression and alcohol use in a single, screened protocol is worth understanding carefully, including where the evidence is strong and where it is still early.
Why does treating one condition at a time so often fail?
Depression and heavy drinking feed each other. Low mood makes a drink feel like relief. The drink deepens the low mood the next day. Each condition makes the other harder to manage, which is why sequential treatment tends to stall.
This overlap is common. In the 2024 National Survey on Drug Use and Health, SAMHSA reported that 21.2 million U.S. adults had both any mental illness and a substance use disorder in the past year. When both conditions exist together, clinicians call it a dual diagnosis. MedlinePlus defines a dual diagnosis as having both a mental disorder and a substance use disorder (SUD) at the same time, also called co-occurring disorders.
The care standard is clear even when the system fails to deliver it. SAMHSA recommends treating co-occurring mental health and substance use disorders at the same time because the symptoms of one make the other worse. Treating them in sequence asks a person to fix one hand while the other keeps pulling it apart.
What do depression and alcohol use share in the brain?
Both conditions involve the same messaging system. Glutamate is the brain’s main excitatory neurotransmitter, and it acts on a receptor called the NMDA (N-methyl-D-aspartate) receptor. Ketamine is an NMDA receptor antagonist. It briefly blocks that receptor and prompts the brain to form new connections, a process called neuroplasticity.
That shared biology matters. The same signaling involved in depressive rumination is also involved in craving. We go deeper into how ketamine supports this window of flexibility in our brief on ketamine, nervous system flexibility, and emotional resilience, so we will not repeat the full mechanism here.
The clinical signal is encouraging. A 2023 systematic review in Cureus found that ketamine was associated with reduced cravings, lower alcohol consumption, and longer abstinence in alcohol use disorder compared with usual care. One of the studies it drew on, the Ketamine for Reduction of Alcoholic Relapse (KARE) trial published in The American Journal of Psychiatry, enrolled 96 people with alcohol use disorder and found that ketamine plus therapy helped them stay abstinent longer than placebo. This evidence is emerging rather than settled, and larger trials are underway.
Isn’t ketamine itself addictive?
It is a fair question, and it deserves a straightforward answer. Ketamine can be misused. Outside of medicine, recreational use involves large, repeated, unsupervised doses, often taken to chase a high. That pattern carries real risk of dependence.
A clinical protocol is very different. In a supervised setting, ketamine is given at a sub-anesthetic dose, a small fraction of the amount used for surgery, during a single monitored session with no medication sent home. The setting removes the conditions that drive misuse: no self-administration, no escalating doses, no take-home supply.
Screening is part of that safety. Before any infusion, a clinician reviews your history and may determine that ketamine is not the right fit, for example if you have certain heart or blood pressure conditions, active psychosis, uncontrolled substance use, or a personal pattern of ketamine misuse. Bipolar disorder calls for careful evaluation too. We cover that in our overview of ketamine’s FDA approval and off-label use. The goal is straightforward: ketamine belongs in the hands of people it can help, given in a way that keeps them safe.
What does an integrated protocol actually look like?
An integrated protocol holds the mood disorder and the alcohol use disorder within one plan, rather than passing you between programs. It usually moves through four stages.
- Evaluation and screening. A medical intake and psychiatric assessment confirm the dual diagnosis, review medications, and check for contraindications.
- Preparation. Sessions before the infusions set intentions and build coping tools, so the experience has direction.
- A supervised infusion series. A course of intravenous (IV) ketamine infusions, delivered under medical monitoring. For a full walk-through of a session, see what to expect from a ketamine infusion for depression and anxiety.
- Integration. Sessions after the infusions turn insight into habit, which is where a biological opening becomes lasting behavior change.
Preparation and integration are the parts people are tempted to skip, yet they are what turn a short window of neuroplasticity into lasting change. Ketamine can loosen an old pattern. The work around it decides whether a new one takes hold. This is why we see ketamine as a catalyst, not a cure. If your care includes pain management alongside mood and alcohol goals, our note on ketamine for pain management covers how those protocols differ.
How do I evaluate a provider for dual diagnosis?
Not every clinic is set up to treat both conditions together. Use this checklist when you compare options, whatever provider you are considering.
- Physician supervision. Infusions should be dosed and monitored by qualified medical staff, not left to self-administration. At Nushama, an anesthesiologist supervises every session.
- Addiction-informed screening. Intake should ask about substance use directly and screen for contraindications, rather than treating mood in isolation. Learn more about how our medical intake and psychiatric assessment works for alcohol use disorder.
- Preparation and integration support. Look for structured sessions before and after the infusions, not just the medicine. Our preparation and integration approach is built into every journey.
- Coordination with your existing care. A good provider will work with your therapist, psychiatrist, or intensive outpatient program (IOP) instead of asking you to abandon them.
- Honest framing of the evidence. Be wary of anyone promising a cure. The research is promising and still developing, and a trustworthy clinician will say so.
Some at-home telehealth services and same-day infusion centers skip the screening or the integration work. That is the difference worth watching for, whoever you choose.
One protocol for both conditions
The checklist above describes how we practice at our Manhattan flagship. Our physician-led IV ketamine infusions take place at 515 Madison Avenue, 21st floor, in Midtown Manhattan (cross street 53rd, steps from the E/M subway entrance). Preparation and integration sessions are built into every journey. Sessions happen in quiet, calming journey rooms rather than a clinical back office, because environment shapes the experience.
The clinic is easy to reach from across the New York metro area. Grand Central is a 15-minute walk, Penn Station connects via the E train (four stops to 53rd Street), and paid parking is available on 53rd between Lexington and Park Avenues.
For members living with both a mood disorder and alcohol use disorder, that means one team, one location, and both goals held together. You can read more about our approach to ketamine for alcohol use disorder, and bring your questions to a consultation whenever you are ready.
We are also following the growing research on GLP-1 receptor agonists and alcohol use disorder. A 2024 retrospective study of over 83,000 patients published in Nature Communications found that semaglutide was associated with a 50–56% lower risk of AUD incidence and recurrence compared with other medications, and multiple tirzepatide-specific trials for alcohol use disorder are now underway. GLP-1 receptor agonists appear to modulate the same dopamine reward pathways involved in craving and compulsive drinking. While this research is still early, Nushama offers GLP-1 therapy as a complementary tool within our existing care plans for members whose clinician determines it may help address alcohol-related cravings alongside ketamine treatment.
If you have felt stuck between two systems that each want the other to go first, there is a path that holds both. Request a consultation at Nushama’s Midtown Manhattan clinic.
Frequently asked questions
Can ketamine treat depression and alcohol use disorder at the same time?
It may help address both within one supervised plan. Ketamine acts on glutamate signaling tied to both low mood and craving, and a 2023 Cureus review found it was associated with reduced cravings and longer abstinence in alcohol use disorder. Results are promising but still emerging, so care should be individualized and medically supervised.
Where is Nushama’s Manhattan ketamine clinic?
Nushama’s flagship is at 515 Madison Avenue, 21st floor, New York, NY 10022, in Midtown Manhattan at 53rd Street. The clinic is next to the E/M subway entrance on 53rd and a short walk from Grand Central. You can reach us at (646) 394-9996.
Is IV ketamine FDA approved for this use?
No. IV ketamine is FDA approved as an anesthetic and is used off-label for psychiatric indications. The FDA approved esketamine (Spravato), a related nasal spray, in 2019 for treatment-resistant depression, but that is a separate medication from IV ketamine.
Will I get addicted to ketamine in treatment?
Clinical ketamine is given at a low, sub-anesthetic dose in a single monitored session with no take-home medication, which removes the conditions that drive misuse. Screening also excludes people with a history of ketamine misuse. This is very different from unsupervised recreational use.
Do I have to stop drinking before I start?
Not necessarily, and that is part of the point of integrated care. Your clinician will assess where you are during screening and build a plan that addresses mood and alcohol use together, rather than requiring you to solve one before the other.
Does ketamine work without therapy?
The medicine opens a window of neuroplasticity, but preparation and integration sessions are what tend to turn that opening into lasting change. Most evidence for alcohol use disorder pairs ketamine with psychological therapy rather than using it alone.
