You did the course. You paid for it. Everyone described it as the thing that works when nothing else does.
Nothing changed, and now you are wondering whether anything will.
Ketamine did not work is a real and reasonably common outcome. It is not a verdict on you, and it is not the end of the options. This page covers what to check first, what can be adjusted, and what comes after.
Ketamine Did Not Work. What That Means
Non-response to ketamine means this treatment, at this dose, by this route, did not produce a meaningful change for you. It does not predict how you will respond to other treatments, since the mechanisms are different. It does not mean your depression is untreatable. It does not mean you did the treatment wrong. A proportion of people do not respond to any given psychiatric treatment, and ketamine is not an exception to that.
Two things are worth separating before you conclude anything.
Whether nothing changed at all, and whether something changed and not enough.
Check These Before Concluding Anything
Several things get mistaken for non-response.
Was the course completed? A response is usually assessed across a series, not after one or two sessions. Stopping partway through is a different situation from completing and not responding.
Was anything measured? Without a baseline score and repeat measurement, “it did not work” is an impression. Depression distorts recall of how you felt weeks ago. Ask for the numbers if they exist.
Were you on a benzodiazepine? There is reasonable evidence that benzodiazepines may blunt the response to ketamine. If you take one regularly, raise it. This is a prescriber conversation and never a reason to stop one on your own.
Did anything else shift? Sleep, appetite, energy and concentration frequently improve before mood. People report no change when sleeping better for the first time in a year.
Has anyone close to you noticed anything? Outside observers often see change the person does not.
Was the diagnosis right? Bipolar depression, undiagnosed ADHD, a thyroid problem, sleep apnea and long-term substance use all present as treatment-resistant depression and need different treatment.
That last one matters more than any dose adjustment. Our post on ketamine for bipolar depression covers one common version.
Adjustments Worth Discussing
Before abandoning the approach entirely.
Dose. Non-response is sometimes under-treatment. This is a clinical decision and no dosing information appears on this page.
Route. Absorption differs considerably between sublingual, intramuscular, intravenous and nasal routes. Someone who does not respond to a sublingual lozenge at home may respond to a monitored route. Our post on routes compared covers the differences.
Session count. Some people need more of the initial series than the standard structure allows.
Interfering medications. Benzodiazepines and, in some accounts, lamotrigine. A prescriber reviews this.
Whether therapy was running alongside. If the plasticity model holds, treatment without any accompanying psychological work may be leaving benefit unclaimed. Our post on integration covers this.
Whether the setting was adequate. An unmonitored, rushed or uncomfortable setting affects the experience and possibly the outcome.
A good clinic will raise several of these before recommending you continue paying. One that suggests only more of the same is worth a second opinion.
Treatments That Come Next
Not responding to one treatment does not predict the others.
Option
What it is
TMS
Magnetic stimulation, around 30 daily sessions, mild side effects, frequently insurance-covered
ECT
Strongest evidence for severe depression, done under anesthesia, memory effects
Spravato
FDA-approved esketamine, different molecule and route, often covered
Medication review
Augmentation strategies, less commonly used classes, a genuine second opinion
Structured psychotherapy
CBT, behavioral activation, trauma-focused work where indicated
Reassessment of diagnosis
Bipolar, ADHD, thyroid, sleep apnea, substance use
Clinical trials
Access to treatments not yet usually available
Our post on ketamine vs TMS vs ECT compares the first three.
Clinical trials deserve a mention people rarely get. Trials are not a last resort for hopeless cases. They offer access to newer treatments with close monitoring, often at no cost. ClinicalTrials.gov lists what is recruiting near you.
What Is Not the Answer
Worth naming plainly.
Continuing to pay for a treatment that is not working. If a completed course produced nothing measurable and adjustments have been tried, more sessions are not the answer.
Increasing frequency on your own initiative. Wanting more sessions after a course that did nothing is worth examining rather than acting on.
Switching to an unmonitored at-home program to get more sessions cheaply. Covered in our post on at home ketamine.
Stopping all treatment. The most common response to a failed course and the most damaging.
Concluding you are untreatable. No clinician can tell you that, and one treatment failing is not evidence of it.
Stopping your other medications. Never do this without your prescriber.
If You Are Losing Hope
A failed treatment is genuinely demoralizing, and it hits hardest when it was framed as the last option.
It was not the last option. This page lists several that remain.

Tell your psychiatrist or therapist that the treatment did not work and how that has left you feeling. That second part is the one people leave out, and it is the part that changes what happens next.
Something worth holding onto. People who have not responded to several treatments do sometimes respond to the next one. Sequence matters, and running out of options is different from not having found the right one yet.
FAQs About Ketamine Not Working
Why did ketamine not work for me? Possible reasons include an incomplete course, dose or route not suited to you, an interfering medication such as a benzodiazepine, a diagnosis that needs revisiting, or simply not responding, which happens with every psychiatric treatment. Ask whether response was actually measured before concluding anything.
How many sessions before I know it is not working? Response is usually assessed across an initial series rather than after one or two sessions, commonly around six over two to three weeks. Judging after a single session is too early. Ask your clinician at what point they would say it is not working.
Can I try ketamine again later? Sometimes, particularly where the route, dose or circumstances change, or where a diagnosis has been revised. Not responding once does not permanently rule it out. Discuss timing rather than rebooking immediately.
Does not responding to ketamine mean nothing will work? No. The mechanisms behind TMS, ECT, Spravato, medication changes and psychotherapy are different, and non-response to one says little about the others. People who have not responded to several treatments do respond to later ones.
Should I stop my antidepressant if ketamine did not work? No. Never stop or change a psychiatric medication without speaking to your prescriber. Several classes carry discontinuation effects and stopping abruptly can worsen symptoms considerably.

If a course of treatment produced nothing, a fresh assessment of the diagnosis and the plan is worth more than another round of the same thing.
