Ketamine for Severe Depression
When the darkness is heavy enough that showering, working, or answering a text feels impossible — waiting six weeks for a pill to maybe work isn't a plan. Ketamine can act in hours.
Not Sad. Shut Down.
Severe depression isn't an intense version of a bad mood — it's a different state altogether. The body feels weighted. Food loses taste. Sleep is broken or endless. Concentration collapses, so work and conversation become performances you can barely sustain. People around you say "reach out if you need anything," and the disease itself makes reaching out feel impossible.
This page is a sibling to our treatment-resistant depression page. That one is about depression that has outlasted multiple medications. This one is about depression whose defining feature is severity — where the urgency of getting functional again is the reason to consider a fast-acting treatment, sometimes alongside the very first medications you try.
When Speed Is Part of the Treatment
Ketamine works on the brain's glutamate system, triggering rapid synaptic repair through neuroplasticity rather than the slow neurotransmitter accumulation of oral antidepressants. In severe depression that difference is clinical, not cosmetic: measurable antidepressant effects within hours to days can restore enough function — sleep, appetite, momentum — to re-engage with work, family, therapy, and the rest of your treatment.
Honest framing: Ketamine is FDA-approved as an anesthetic; its use for depression is off-label, supported by a substantial body of controlled research showing rapid symptom reduction, with response rates in studies commonly in the 50–70% range. Effects of individual infusions are temporary, which is why treatment runs as a series with maintenance as needed. Individual results vary and are never guaranteed.
How We Treat Severe Depression at Desert Sands
Your evaluation covers symptom severity and history, safety, prior treatments, medical background, and current medications. Treatment protocols are physician-directed and supported by experienced clinical staff under the medical oversight of board-certified anesthesiologist Dr. Eric Evans, whose more than 30 years of clinical experience help guide the highest standards of patient safety, comfort, and care. Because severe depression can involve safety concerns, your evaluation includes a candid conversation about them — and if what you need is a higher level of care than an outpatient clinic, we will tell you that directly and help you get there.
A typical course is six infusions over two to three weeks in a private treatment room at sub-anesthetic doses calibrated to you, with continuous monitoring, followed by individualized maintenance. We coordinate with your psychiatrist or therapist whenever you want us to.
Patient Selection
- Have severe depressive symptoms significantly impairing daily function
- Can't afford the 4–8 week wait for oral antidepressants to take effect
- Have responded poorly or partially to medications in the past
- Are connected to, or willing to connect with, ongoing mental-health care
- An immediate safety crisis — that calls for emergency care today, not a scheduled infusion
- Uncontrolled high blood pressure or unstable cardiovascular disease
- A history of psychosis or schizophrenia
- Active substance-use concerns that haven't been evaluated
Outcomes, Honestly Stated
Responders often describe the earliest change as space — the weight easing enough to think, sleep, and act. That functional recovery frequently precedes full mood recovery, and it's what makes the rest of treatment possible. Benefit builds across the series; some patients respond early and strongly, some partially, some not at all, and we will always tell you which we're seeing.
Risks and side effects
During and shortly after infusion, patients may experience dissociation, elevated blood pressure or heart rate, nausea, dizziness, or drowsiness. These effects are typically temporary and most resolve within about two hours. Every patient is screened before treatment and monitored continuously throughout, and you'll need a ride home after each session.
What the Research Shows
Randomized controlled trials beginning at the National Institute of Mental Health established ketamine's rapid antidepressant effect, with symptom reduction measurable within 24 hours — findings replicated across dozens of subsequent studies and repeated-infusion protocols in severely depressed populations.
Severe Depression FAQ
Do I have to fail other medications first?
Not necessarily. Severity itself — the inability to function while waiting on slower treatments — is part of the clinical picture Dr. Evans's team weighs. Your evaluation answers this for your specific situation honestly.
What if I'm too depressed to organize all this?
We've built the process for exactly that. One phone call starts it, Shannon walks you through every step, and a family member or friend can help coordinate with your permission. Bring your support person — they can drive you home anyway.
