How to Get Prescribed Ketamine Treatment

To get prescribed ketamine treatment, you generally need a clinical evaluation by a qualified provider who confirms you have a condition ketamine may help, rules out reasons it would be unsafe, and determines that you have not responded adequately to standard treatments. Ketamine is a controlled, prescription-only medication, so it cannot be obtained over the counter or online without a legitimate medical assessment. The path typically involves finding a reputable clinic or telehealth program, completing an intake and medical screening, and then beginning supervised treatment if you are a good candidate.

How to get prescribed ketamine treatment: the basic path

While details vary by provider and country, most patients move through a similar sequence:

1. Identify a legitimate provider. This may be a dedicated ketamine clinic, a psychiatry or anesthesiology practice, or a licensed telehealth program offering at-home oral ketamine.
2. Complete an intake assessment. You will share your medical history, current symptoms, medications, and prior treatments.
3. Undergo a medical and psychiatric evaluation. A clinician confirms eligibility and screens for safety risks.
4. Receive a treatment plan. If appropriate, the provider prescribes a specific route (IV infusion, intramuscular injection, intranasal esketamine, or oral lozenges) and schedule.
5. Begin monitored treatment with follow-up to track response and adjust the plan.

Who qualifies for ketamine treatment?

Ketamine and the related medication esketamine (Spravato) are most commonly used for treatment-resistant depression — depression that has not improved after trying two or more antidepressants. Studies suggest ketamine may also help with conditions including:

• Treatment-resistant or severe major depression
• Depression with suicidal ideation, in certain monitored settings
• Post-traumatic stress disorder (PTSD)
• Certain anxiety and obsessive-compulsive conditions
• Some chronic pain conditions, often managed by pain specialists

Only intranasal esketamine carries U.S. FDA approval for treatment-resistant depression and depression with suicidal thoughts. Other ketamine uses for mental health are typically prescribed "off-label," which is legal and common but means the specific use was not formally evaluated by regulators.

What providers screen for

Because ketamine affects blood pressure, heart rate, and mental state, clinicians evaluate your safety carefully. Factors that may require caution or rule out treatment include uncontrolled high blood pressure, certain heart or vascular conditions, a history of psychosis or mania, active substance use disorder involving ketamine, pregnancy, and some liver or bladder conditions. Being honest during screening protects you. Learn more about how this is handled in our ketamine safety hub.

Where to seek a prescription

There are two broad routes, each with trade-offs:

Option	Typical setting	Best suited for
In-person clinic	IV infusions or IM injections with on-site monitoring	Higher-acuity cases, those wanting direct supervision
Telehealth program	Oral/sublingual ketamine prescribed and shipped, with remote check-ins	Stable patients seeking lower-cost, at-home convenience
Psychiatry/specialty practice	Esketamine (Spravato) in a certified office under a federal safety program	Patients pursuing the FDA-approved nasal option

If you are weighing the at-home route, our guide to at-home telehealth ketamine explains how remote prescribing and monitoring work and what makes a program legitimate.

How to evaluate a provider before committing

Quality and safety vary widely, so vetting matters. Look for providers who:

• Require a thorough medical and psychiatric intake before prescribing
• Are staffed or overseen by licensed clinicians (psychiatrists, anesthesiologists, or appropriately trained prescribers)
• Provide monitoring during and after dosing, or clear safety protocols for at-home use
• Integrate follow-up, therapy, or coordination with your existing care team
• Are transparent about costs, risks, and realistic expectations — and avoid promising guaranteed results

A provider who offers a prescription with no real evaluation is a warning sign. Our guide to choosing a ketamine provider walks through specific questions to ask.

What it costs and how to pay

Ketamine for mental health is frequently paid out of pocket because many insurers do not cover off-label infusions. Esketamine (Spravato) is more often covered when prescribed per its approved indication, though prior authorization is common. Costs depend on the route, the number of sessions, and your location. Reviewing options in advance helps you avoid surprises — see our cost and insurance resources for what to expect and how to ask about coverage.

Preparing for your evaluation

To make your assessment efficient and accurate, gather your list of past and current medications, records of previous treatments and their outcomes, and a summary of your symptoms over time. Be prepared to discuss alcohol and substance use, and bring questions about the treatment route, frequency, side effects, and follow-up. The more complete your information, the better a clinician can decide whether ketamine is appropriate for you.

Frequently Asked Questions

Can I get ketamine prescribed online?

Yes, some licensed telehealth programs can legally prescribe oral or sublingual ketamine after a proper medical and psychiatric evaluation. However, a legitimate program always requires screening first; any service offering ketamine without a real assessment should be avoided.

Do I need a referral from my doctor to get ketamine treatment?

A referral is not always required, as many clinics and telehealth providers accept self-referrals. That said, coordinating with your primary care doctor or psychiatrist is encouraged so your overall care stays consistent and safe.

What conditions can ketamine be prescribed for?

Ketamine is most commonly used for treatment-resistant depression, and studies suggest possible benefit for PTSD, certain anxiety conditions, and some chronic pain. Only intranasal esketamine is FDA-approved for depression; other uses are typically off-label.

Why might a provider decline to prescribe ketamine?

Providers may decline if you have uncontrolled high blood pressure, certain heart conditions, a history of psychosis or mania, active substance misuse, pregnancy, or other safety concerns. These screenings exist to protect you from serious risks.
