Do You Qualify for Ketamine Therapy?

You've done the research. You've read about how ketamine therapy can help when antidepressants haven't, and now you're wondering whether you'd actually qualify.

You're not alone. Roughly one in five people being treated for depression in primary care meet the criteria for treatment-resistant depression. That's a lot of people stuck between treatments that haven't worked and options that feel uncertain.

The short answer: You may qualify for ketamine therapy if you have depression, anxiety, or post-traumatic stress disorder (PTSD), and you don't have certain cardiovascular, liver, or psychotic conditions that make treatment unsafe. Ketamine can also help when traditional treatments haven't worked, and it can be considered as a first-line option before or instead of SSRIs.

Which Mental Health Conditions Qualify?

Ketamine therapy is most commonly used for treatment-resistant depression, which has the strongest evidence base and is the only condition (in its esketamine form) with U.S. Food and Drug Administration (FDA) approval.

A separate FDA approval covers depressive symptoms in adults with major depressive disorder who have acute suicidal ideation or behavior, and esketamine is one of the few medications shown to rapidly reduce depressive symptoms in this population.

Ketamine works through a different mechanism than traditional antidepressants. Rather than targeting serotonin, it promotes neuroplasticity: the brain's ability to form new neural connections in regions affected by depression and anxiety.

Beyond these FDA-approved uses, many clinicians prescribe ketamine off-label for other conditions:

• PTSD has moderate research support, especially when first-line options haven't led to remission.
• Generalized and social anxiety also have moderate evidence that ketamine can ease symptoms.
• Obsessive-compulsive disorder (OCD) has limited but promising early research, and bipolar depression shows rapid antidepressant effects in short-term studies.

The distinction between FDA-approved and off-label matters, but not in the way many people assume. Off-label prescribing is both common and legal in medicine, though clinical screening matters even more for these uses. The risk-benefit conversation becomes more individualized.

When Ketamine Isn't Safe

Some conditions make ketamine genuinely unsafe. A thorough screening process will catch these early, and your clinician should be straightforward about them.

Conditions That Rule Out Treatment

These include:

• Uncontrolled high blood pressure or serious heart disease. Ketamine temporarily raises blood pressure and heart rate. If you have unstable cardiovascular disease, an aneurysm, or a history of brain bleeding, those temporary spikes can pose serious risks, as reflected in ketamine's FDA label. Many protocols require blood pressure to be well-controlled, often below 140/90, before treatment begins.
• Active psychosis or schizophrenia. Ketamine can produce dissociative effects and hallucinations, which means it can worsen existing psychotic symptoms. If you have a current or historical diagnosis of schizophrenia or schizoaffective disorder, ketamine is not appropriate.
• Active substance use disorder. Most protocols require substance use concerns to be in remission. Past substance use in stable recovery is evaluated individually.
• Severe liver disease. The liver processes ketamine, and severe dysfunction like cirrhosis can lead to dangerous buildup.
• Pregnancy. Animal studies suggest potential risks to fetal development, so pregnancy must be ruled out before treatment.
• Known allergy to ketamine. Any documented allergic reaction rules out treatment entirely.

When Eligibility Is Conditional

Some situations fall into a gray zone:

• Moderately elevated blood pressure that responds to medication adjustment.
• Moderate liver concerns with stable enzyme levels.
• Elevated eye pressure.

While these don't automatically rule you out, they do require additional evaluation before treatment can proceed. Still, a "no" today doesn't always mean "no" permanently. Getting blood pressure under control, building a longer track record of recovery from substance use, or obtaining cardiac clearance can shift the picture.

Innerwell's eligibility guide covers these edge cases in more detail.

If ketamine isn't the right fit for your situation, other paths are available. Innerwell also offers talk therapy, EMDR, and psychiatric care for people who need a different treatment approach.

What "Treatment-Resistant" Actually Means

Many people aren't sure whether they actually meet this threshold. Treatment resistance has a specific clinical definition: you've tried at least two antidepressant medications without adequate improvement. But not every prescription you've been on counts toward that number.

An adequate trial means two things happened: the medication was prescribed at a therapeutic dose, and you took it long enough for it to work. The traditional standard is four to six weeks, though some people need longer for a full response.

If you stopped a medication after two weeks because of side effects, that may not count as a complete trial.

Two trials that didn't work is the baseline. In practice, some programs look for more history, especially if your records are incomplete or your past trials were borderline in dose or duration. Needing several attempts isn't a failure. It's common.

How Current Medications Affect Eligibility

A common worry is that you'll need to stop all your medications before trying ketamine. For most people, that isn't the case.

Selective serotonin reuptake inhibitors (SSRIs), serotonin-norepinephrine reuptake inhibitors (SNRIs), bupropion, and mirtazapine are generally safe to continue during ketamine treatment. Research suggests ketamine's effects hold whether or not you're on other antidepressants.

Benzodiazepines are the main concern. They won't rule you out, but research shows they can reduce ketamine's therapeutic benefits. Your care team may work with you on tapering before treatment starts. Never stop benzodiazepines abruptly; always discuss changes with your prescriber first.

Monoamine oxidase inhibitors (MAOIs) require closer blood pressure monitoring but aren't an automatic barrier. Lithium and other mood stabilizers are generally compatible with ketamine, though your care team will want to coordinate closely if you're being treated for bipolar depression.

What the Screening Process Involves

Innerwell's screening is thorough, and because the program is at-home, you complete everything virtually. The assessment typically includes a psychiatric evaluation to confirm your diagnosis and document your medication history, basic lab work covering liver and kidney function, a cardiovascular check including blood pressure and sometimes an electrocardiogram, a substance use screening, and a pregnancy test if applicable.

The psychiatric evaluation is the cornerstone. Your clinician needs to confirm you meet treatment-resistance criteria with documented medication trials. It helps to come prepared with records of what you've tried: medication names, doses, how long you took each one, and why you stopped. If your records are incomplete, write down what you can remember. Even approximate dates and dosages help.

The complete screening process typically takes one to four weeks, depending on scheduling and whether additional clearance is needed. After you're approved, monitoring continues throughout treatment with blood pressure checks before and after every session and ongoing tracking of how you're responding.

How Innerwell's At-Home Ketamine Therapy Works

If you think you might qualify, the next question is what treatment actually looks like. Innerwell offers at-home ketamine therapy that pairs sublingual ketamine tablets with licensed therapeutic support.

Unlike medication-delivery services with minimal supervision, Innerwell is a structured clinical program built around a core principle: ketamine promotes neuroplasticity, and that window of increased flexibility in the brain is most valuable when you use it intentionally. The medication opens a door; therapy helps you walk through it.

That's why the program builds preparation and integration into every step, not as optional add-ons, but as part of how the treatment works.

The process:

1. Evaluation: Innerwell's own psychiatric team conducts the screening described above as part of the virtual intake process.
   Delivery: A licensed pharmacy ships sublingual ketamine tablets to your home with adult-signature verification. No IV clinics, no scheduling around infusion appointments.
2. Preparation and integration: Licensed Master's and Doctoral level therapists, not unlicensed guides, work with you before and after sessions to help you process what comes up and build lasting change.
3. Ongoing monitoring: Your care team tracks your progress and adjusts dosing as needed throughout the program.

Frequently Asked Questions

Do I need a referral from my current doctor?

No. Innerwell's evaluation includes a full psychiatric and medical assessment. That said, if you have documentation of past medication trials, bringing it to your evaluation helps confirm you meet treatment-resistance criteria faster.

What does a ketamine session actually feel like?

Most people experience altered perception, a sense of floating, and emotional shifts that last 45 minutes to an hour. Some describe it as dreamlike. The dissociative effects are temporary and expected, and your care team prepares you beforehand so you know what to anticipate. Effects typically fade within a few hours.

Can I do ketamine therapy while seeing another therapist?

Yes. Many people continue working with an existing therapist while doing ketamine therapy. Innerwell's integration sessions focus specifically on processing what comes up during treatment, which complements rather than replaces other therapeutic work.

Is there a minimum or maximum age?

The minimum age is 18. Research on ketamine therapy in adolescents remains extremely limited, so most programs treat adults only. There's no maximum age; eligibility for older adults depends more on cardiovascular health and blood pressure control than on age itself.

Is ketamine therapy FDA-approved?

Esketamine (Spravato), a nasal spray form, has FDA approval for treatment-resistant depression and for depressive symptoms with acute suicidal ideation. It requires in-clinic administration. The sublingual ketamine used in at-home programs like Innerwell's is prescribed off-label, which is a common and legal practice in medicine. The FDA has also cautioned people about risks associated with compounded ketamine.
