Key takeaways
- Ketamine for anxiety is used off-label, meaning it is not FDA-approved for anxiety but may be prescribed by a clinician when other treatments have not worked.
- Ketamine works on the brain’s glutamate system, which is different from how most anxiety medications work and may explain why relief can come faster.
- Early research suggests ketamine can lower symptoms in people with treatment-resistant anxiety, though the studies so far are small.
- Ketamine for anxiety is not right for everyone, and a careful evaluation helps decide if it may be a good fit.
- At Pacific Mind Health, ketamine is offered as an intranasal or sublingual treatment, sometimes paired with therapy.
Ketamine for anxiety is an off-label treatment that may quickly reduce severe or treatment-resistant anxiety symptoms. It works on the brain’s glutamate system rather than serotonin, which can bring relief faster than traditional medications. While not approved by the US Food and Drug Administration (FDA) for anxiety, early research and clinical use suggest it can help some people when other treatments have not.
If you have been living with anxiety that won’t ease up, you may be wondering whether ketamine for anxiety could be an option worth exploring. Maybe you have already tried therapy, medication, or both, and you’re still searching for relief. This guide explains what ketamine is, how it may help with anxiety, who it tends to suit, and what treatment can look like, so you can have a more informed conversation with a provider.
What is ketamine for anxiety?
Ketamine for anxiety is the off-label use of ketamine to ease anxiety symptoms, usually in people who have not responded well to standard treatments. Ketamine is a medication first approved as an anesthetic, and over the past two decades researchers have studied its effects on mood and anxiety.
Anxiety is very common. An estimated 19.1% of U.S. adults had an anxiety disorder in the past year, and about 31.1% experience one at some point in their lives. For many people, therapy and standard medications work well. But when they don’t, it can feel discouraging, and that is often where newer options like ketamine enter the conversation.
Ketamine is not FDA-approved to treat anxiety. When a clinician uses it for this purpose, that is considered off-label, a common and legal practice in medicine where a provider prescribes an approved medication for a different use based on clinical judgment and emerging evidence.
How does ketamine work to ease anxiety?
Ketamine works differently from most anxiety medications. Instead of acting mainly on serotonin, it targets the brain’s glutamate system by blocking a receptor called the NMDA receptor, which may help the brain form new connections in areas that regulate mood and stress.
This different mechanism is one reason ketamine has drawn so much interest. Many traditional medications can take weeks to take effect. Ketamine, by contrast, has been observed to lower symptoms more quickly in some people, sometimes within hours or days.
That speed can matter a great deal for someone who has been stuck in cycles of anxiety for a long time. Still, ketamine is not a cure, and its effects can fade over time, which is why treatment is usually planned and monitored carefully.
Who might benefit from ketamine for anxiety?
Ketamine for anxiety is generally considered for adults whose anxiety has not improved after trying other evidence-based treatments, such as therapy and standard medications. It is not usually a first step.
Most of the research so far has focused on people with treatment-resistant generalized anxiety disorder (GAD) and social anxiety disorder (SAD). In one small study, weekly ketamine over three months helped reduce anxiety symptoms in adults whose anxiety had not responded to at least two prior treatments. A later double-blind study reported similar anxiety-lowering effects, adding to the early evidence.
While these results are promising, more research is needed. Anxiety also often travels alongside depression, and ketamine may be discussed as an option when both are present. A thorough evaluation is the best way to understand whether it may be appropriate for your situation.
“For someone who has spent years cycling through treatments without relief, the possibility of feeling better in days rather than weeks can be genuinely meaningful,” said Joshua Flatow, MD, medical director and chief psychiatrist at Pacific Mind Health. “That’s why we take time to evaluate each person carefully. Ketamine isn’t right for everyone, but for the right person it can open a door that felt closed.”
Is ketamine for anxiety safe and legal?
Ketamine is a legal, FDA-approved medication, and using it off-label for anxiety is allowed when prescribed by a qualified clinician. When given in a medical setting at carefully controlled doses, it is generally considered safe, though it does carry possible side effects.
During treatment, some people feel temporary dissociation, a dreamlike or disconnected sensation, along with mild dizziness, nausea, or a short rise in blood pressure. These effects usually pass the same day, which is why treatment includes monitoring. Research into ketamine for anxiety also continues to study its long-term safety.
Because ketamine can be misused, it should only be taken under medical supervision and never on your own. If you or someone you know is in crisis, call or text 988 to reach the Suicide and Crisis Lifeline.
How is ketamine for anxiety used at Pacific Mind Health?
At Pacific Mind Health, ketamine for anxiety is offered as an intranasal (nasal spray) or sublingual (under-the-tongue) treatment, given under medical supervision. It may also be paired with therapy in an approach called ketamine-assisted therapy, which combines the medication with guided psychological support.
For people whose anxiety occurs with treatment-resistant depression, a related FDA-approved option called Spravato® (esketamine) may also be discussed. Spravato is a nasal spray approved for treatment-resistant depression, and it works on the same glutamate system as ketamine.
Every plan starts with an evaluation by a provider, who reviews your history, current symptoms, and past treatments to recommend the safest, most appropriate path. Treatment is always monitored, and your provider will adjust the approach based on how you respond.
Looking for Spravato or ketamine treatment near you?
Pacific Mind Health offers Spravato (esketamine) and ketamine therapy for treatment-resistant depression, major depressive disorder, and more.
Located in Southern California and serving patients across the state, Pacific Mind Health was founded by Joshua Flatow, MD, a board-certified psychiatrist and published research author.

Frequently asked questions
Is ketamine FDA-approved for anxiety?
No. Ketamine is not FDA-approved to treat anxiety, so its use for this purpose is considered off-label. Off-label prescribing is a common and legal practice where a clinician uses an approved medication for a different use based on clinical judgment and emerging research. A related medication, Spravato (esketamine), is FDA-approved for treatment-resistant depression but not for anxiety.
How quickly does ketamine work for anxiety?
Ketamine may lower anxiety symptoms faster than traditional medications, sometimes within hours or days rather than weeks. However, the effects can fade over time, so treatment is usually planned and monitored. Individual responses vary, and not everyone experiences fast relief.
Is ketamine for anxiety safe?
When given at controlled doses under medical supervision, ketamine is generally considered safe, though it can cause temporary side effects like dissociation, dizziness, or nausea that usually pass the same day. Because ketamine can be misused, it should only be taken under a clinician’s care. A provider evaluates your health history to help reduce risks.
Who should not use ketamine for anxiety?
Ketamine for anxiety is not right for everyone. It is typically considered only after other treatments have been tried, and it may not be appropriate for people with certain medical or psychiatric conditions. The best way to know if it may be a fit is through an evaluation with a qualified provider.
What’s the difference between ketamine and Spravato for anxiety?
Both ketamine and Spravato (esketamine) work on the brain’s glutamate system. The key difference is that Spravato is FDA-approved for treatment-resistant depression, while ketamine used for anxiety is off-label. A provider can explain which option, if any, may suit your needs.
