Two medication trials in, and the next conversation is often about ketamine and TMS. They could not feel more different. One is a medication given under monitoring. The other is magnetic stimulation while you sit awake in a chair. So when a patient asks me about ketamine vs TMS, my first answer is usually quieter than they expect, because neither one wins for everyone. What tends to decide it is your diagnosis, your timeline, what your insurance covers, and whether you can get to weekly appointments – not the name on the door.
Our take comes with a built-in bias check. At Washington Behavioral Medicine Associates, we run both ketamine therapy and TMS therapy in the same practice. So the ketamine vs TMS discussion is not being steered toward the one machine we happen to own. I can lay out where each treatment helps and where it falls short, and still point you somewhere else entirely if that fits you better.
Treat this as prep for your consultation. First the clinical differences, then the practical things that usually settle the plan – time off work, who drives you home, side effects, coverage, and how fast you need your symptoms to move.
Why the Ketamine vs TMS Question Comes Up
Start with a number. At least 30% of people with depression do not get enough relief from their first medications. That is roughly the line for treatment-resistant depression, which usually means an inadequate response to two antidepressants taken at a real dose for a real length of time. Once you are there, looking past standard prescriptions toward neuromodulation services and other options is a reasonable next step.
Ketamine and TMS earned their place in that conversation for one reason. They do not work like the pills that came before them. Older antidepressants nudge serotonin over weeks. TMS works through magnetic pulses aimed at the mood circuits. Ketamine and esketamine act on glutamate, the signaling system tied to how the brain forms new connections. For someone who has not improved on medication alone, that difference in mechanism can change the whole recommendation.
How TMS Therapy Works
From the patient’s side of the chair, TMS is the undramatic one. You stay awake. A coil rests against your scalp and sends focused magnetic pulses into the brain regions that regulate mood. No anesthesia, no medication to absorb.
The FDA cleared rTMS for depression in people who did not respond to at least one antidepressant in the current episode, and later cleared it for severe obsessive-compulsive disorder.
Plan on weekday sessions across 4 to 6 weeks, with visits of about 20 to 40 minutes, though some courses run longer. Because nothing enters your system, TMS sidesteps the weight changes, sexual side effects, and fatigue that some people get from oral antidepressants.

How Ketamine and Spravato Work
Ketamine goes a different route. It acts on glutamate, the brain chemical behind how neurons build and rework their connections, and for some people with treatment-resistant depression that can mean relief arriving faster than a typical antidepressant. One distinction matters before anything else, because ketamine and Spravato are not the same thing.
- Esketamine (Spravato) is a nasal spray that is FDA-approved for treatment-resistant depression in adults and must be given under medical supervision through a restricted REMS program. You can read more about it in our overview of Spravato treatment.
- Intravenous (IV) ketamine is used off-label for depression. Clinicians may use it legally when it is appropriate, but the FDA has not approved IV ketamine as a depression treatment.
Research reviews put ketamine in the rapid-acting category for treatment-resistant depression, with the honest caveat that response and durability vary from person to person. Either way, it is given in office under monitoring, and that supervision is part of the treatment rather than red tape. Spravato follows a set induction and maintenance schedule. IV ketamine protocols shift with the clinician, your history, and how you respond.
Ketamine vs TMS – The Side-by-Side Comparison
The table pulls together the practical ketamine vs TMS differences patients ask about most. Read it as a list of questions for your visit, not a scorecard. Your history is what actually decides the recommendation.
| What to compare | TMS Therapy | Ketamine / Spravato |
|---|---|---|
| How it works | Magnetic pulses stimulate mood-regulating brain regions | Acts on glutamate signaling tied to neural connections |
| FDA status | FDA-cleared for depression and severe OCD | Spravato FDA-approved for TRD; IV ketamine off-label |
| How it is given | Awake, in office, magnetic coil on the scalp, no medication | In-office nasal spray or IV infusion under monitoring |
| Typical course | Weekday sessions over 4 to 6 weeks; some plans run longer | Spravato uses induction and maintenance phases; IV protocols vary |
| When relief may begin | Usually gradual, often over a few weeks; effects may last after the course | Often faster for some patients, especially during the early course |
| Common side effects | Scalp discomfort and mild headache during or after sessions | Short-lived dissociation, dizziness, sedation, or raised blood pressure |
| Insurance coverage | Often covered for TRD after prior medication trials | Spravato is often covered; IV ketamine is usually self-pay |
| Often considered for | Patients who want a non-drug option and can commit to frequent visits | Patients who need faster relief and can be monitored after each treatment |
How WBMA Decides Which to Recommend
Being evaluated where both treatments already live has a practical upside. The conversation starts with you, not with the equipment list. A single-treatment clinic has a shorter menu by definition. When someone brings us the ketamine vs TMS question, our psychiatric care team opens with the diagnostic picture, your symptoms, the medications you have already tried, your other conditions, your schedule, and your coverage, before anyone names a treatment.
And because both live under one roof, the care stays joined up. We can land on TMS, ketamine, Spravato, or a staged plan without shipping you off to another clinic to start the workup over.
Gonzalo Laje, MD, WBMA’s founder and director, is a psychiatrist, clinical researcher, author, and speaker whose work spans medication management and neuromodulation. The practice’s approach centers on matching the treatment to the patient’s diagnosis, urgency, and circumstances instead of defaulting to one intervention. Offering both treatments in one practice makes that assessment more practical, and you can read Gonzalo Laje’s background before your visit.
When TMS and Ketamine Are Used Together
They are not always an either-or. Sometimes clinicians sequence or combine them, using ketamine or Spravato for fast early relief while TMS builds underneath it over the following weeks. A plan like that needs close psychiatric supervision, because the evidence for combining the two is still maturing.
The research context matters here. The National Institute of Mental Health lists TMS among FDA-authorized brain stimulation therapies used for depression that has not responded to standard treatment. Any combined plan should be supervised by a psychiatrist who can monitor your response over time.
Which Option Fits Your Situation
No table can replace an evaluation. Still, a few patterns can help you walk in prepared. Bring whichever ones sound like you.
- TMS may be worth discussing if you want to avoid adding another medication, can commit to frequent sessions for a few weeks, and prefer a non-systemic treatment.
- Ketamine or Spravato may be worth discussing if speed of relief matters, medication side effects have been difficult, or monitored treatment visits fit your schedule.
- A combined or staged plan may be worth discussing if your depression is severe, prior treatments have not helped enough, or your psychiatrist thinks faster early relief should be paired with a longer treatment plan.
Frequently Asked Questions
Is TMS more effective than ketamine for treatment-resistant depression?
No treatment is universally more effective for every patient. Research supports both TMS and ketamine for treatment-resistant depression, with different strengths. Ketamine is often discussed for faster onset, while TMS may be the better fit when a non-drug option and durability matter most. In the end, your diagnosis, history, and timing needs decide it.
Can you do TMS and ketamine at the same time?
In some cases, yes. Some patients use ketamine or Spravato for rapid early relief and TMS for longer-term support, under close psychiatric supervision. Combined approaches remain an area of active clinical study, so the decision should be made with a psychiatrist who can monitor your response.
Does insurance cover TMS or Spravato more easily?
Both are frequently covered for treatment-resistant depression after other medications have been tried, though requirements vary by plan. IV ketamine is the outlier – it is typically not covered and is usually offered as a self-pay option. Our team can help you understand what your specific coverage may include.
What are the side effects of TMS compared to ketamine?
TMS side effects are usually mild, mostly scalp discomfort or a brief headache during sessions. Ketamine and Spravato can cause short-lived dissociation, dizziness, sedation, or a temporary rise in blood pressure, which is exactly why treatment happens under monitoring. Both have established safety protocols in a clinical setting.
How fast does TMS work compared to ketamine?
Ketamine is often the faster-acting option, with some patients noticing changes early in treatment. TMS tends to work more gradually, building across the treatment course. If speed of relief is a priority for you, that gap is worth a direct conversation during your evaluation.
Do I have to choose between ketamine and TMS on my own?
No. At a practice that offers both, a psychiatrist helps you work through the ketamine vs TMS decision based on your situation. You bring your history and goals, and the clinical team explains which option, sequence, or combination may be appropriate.
Taking the Next Step
The ketamine vs TMS decision gets a lot easier when the starting point is your symptoms instead of a single clinic’s menu. Both are serious, well-studied options for depression that standard care has not reached. In our practice, the right one is simply the one that fits your diagnosis, your timeline, your medical history, and your daily life.
