Ketamine is the most accessible form of psychedelic-assisted therapy in the United States — available in outpatient clinics and, in some cases, at home. For treatment-resistant depression, it can lift mood in hours or days, not the weeks conventional antidepressants take.
Ketamine was developed in the 1960s and has been used safely as an anesthetic in hospitals worldwide ever since. In the last two decades, researchers discovered that at much lower doses it does something remarkable: it can rapidly lift severe, treatment-resistant depression — often within hours.
It's a dissociative — at therapeutic doses it produces a gentle, floaty separation from ordinary thought that, held in the right setting, can open a window for real change. And because it's already an approved medicine, it's legal and accessible in the U.S. right now.
The form changes the setting, the intensity, and the cost. Here's how the main routes compare.
Reputable ketamine therapy starts at an outpatient clinic with a proper intake: a psychiatric evaluation, a medical review, and often a urinalysis. You're assessed for fit before anything begins.
From there it's usually a series — a common protocol is a set dose given one to four times a month across about six weeks, followed by maintenance sessions as needed. You're monitored during each session and rest before heading home with a driver.
Conventional antidepressants nudge serotonin over weeks. Ketamine works on a different system entirely, and far more quickly.
A psychiatric evaluation, medical review, and often a urinalysis — to confirm ketamine is a safe, sensible fit for you.
At an outpatient clinicYou receive your dose (IV, injection, nasal, or lozenge) in a quiet room, monitored by staff. Most feel a gentle, floaty dissociation — dreamlike, not frightening.
Effects fade within an hour or so. You rest until you're clear, then head home with a driver — no driving that day.
A typical protocol is a set dose one to four times a month over roughly six weeks — the repetition is part of how the benefit builds.
Maintenance sessions as needed, ideally alongside therapy to turn the relief into lasting change.
A dreamy, dissociative drift — separated from the usual weight of thoughts, often calm and curious.
Many describe stepping back from a heaviness that felt permanent — and remembering it doesn't have to be.
A lift in mood the same day or the next — striking after years of slow-acting medications.
A softer, wider view of problems that felt immovable — space to think differently.
Some nausea or wooziness during the session that passes quickly with rest.
People who pair sessions with integration therapy tend to hold the gains longer.
Ketamine has decades of medical use behind it and is well-tolerated in a proper clinical setting. The cautions are straightforward and easy to manage with a reputable program.
Because ketamine can be misused, the setting matters. A reputable program screens you, supervises sessions, and paces treatment responsibly.

Speak With An Advisor →Yes. Ketamine is used off-label for depression and esketamine (Spravato) is FDA-approved for treatment-resistant depression.
Many people notice relief within hours of the first infusion; effects fade without maintenance.
A typical induction is six sessions over two to three weeks, then maintenance.
Roughly $400–$800 per infusion in most US clinics; Spravato is sometimes covered by insurance.
