Depression and other mental health disorders like obsessive-compulsive disorder (OCD) are both common and serious. They affect how you feel, think, and function at home and work. When your symptoms don’t improve with traditional antidepressants and psychotherapy, it can feel discouraging.
Choosing between transcranial magnetic stimulation (TMS) and ketamine/Spravato can feel overwhelming, especially when you’re searching for relief after other treatments haven’t helped enough. While both are effective ways to treat a variety of disorders, both options work in very different ways:
- TMS uses targeted magnetic stimulation to influence mood‑related brain circuits
- Ketamine/Spravato acts chemically to rapidly shift patterns of thought and emotion.
Each has its own strengths, pace of improvement and ideal clinical fit.
At AwakeningsKC, we offer effective, proven outpatient therapies that help people reclaim their lives. Two of our leading therapies are transcranial magnetic stimulation and rapid-acting therapies such as ketamine and esketamine (Spravato).
Overview: How TMS and Ketamine/Spravato Work
Transcranial magnetic stimulation and ketamine/Spravato target the brain in very different but complementary ways to relieve treatment resistant depression and other disorders.
TMS
TMS is a noninvasive, FDA-cleared treatment that uses focused magnetic pulses to stimulate brain regions involved in mood regulation, often the prefrontal cortex. Sessions take place in our outpatient clinic while you are awake and seated.
A typical acute course involves short daily sessions five days per week for four to six weeks. Newer protocols can reduce session length while preserving clinical benefit.
Comparing Ketamine and Spravato
Ketamine and Spravato address mood through systemic pharmacology. Ketamine is often administered by intravenous infusion in specialized clinics. Spravato is the brand name for an FDA-approved nasal spray form of ketamine.v Ketamine therapy targets glutamate receptors and related pathways, rapidly modulating neural circuits that influence mood and cognition. Relief can begin within hours to days.
In simple terms, TMS delivers localized stimulation to specific cortical networks without circulating medication throughout the body. Ketamine and Spravato rely on medication absorbed into the bloodstream, with in-clinic monitoring during and after dosing.
A side-by-side comparison:
| Feature | TMS | Ketamine/Spravato |
| How it works | Localized magnetic stimulation of mood-related brain circuits | Systemic medication that modulates glutamate and related pathways |
| Onset of effect | Days to weeks; often noticeable by week 2–3 | Hours to days after dosing |
| Course and maintenance | Daily sessions for 4–6 weeks; maintenance or retreatment as needed | Induction series followed by scheduled maintenance dosing |
| Common side effects | Scalp discomfort, mild headache; no sedation or systemic side effects | Dissociation, dizziness, nausea, transient blood pressure and heart rate rise |
| Monitoring needs | No post-session observation; resume normal activities | In-clinic supervision with observation; no driving until the next day |
| Candidacy considerations | Non-systemic; useful for medication sensitivities or drug-interaction concerns | Rapid relief prioritized; cardiovascular and psychiatric screening required |
| Insurance landscape | Often covered for treatment-resistant depression | Spravato is commonly covered under REMS; ketamine coverage varies by plan |
TMS vs. Ketamine/Spravato: Do They Work?
Studies have shown that TMS therapy is at least partially effective over 50 percent of the time. Many people maintain improvement for months, and benefits can be extended with periodic maintenance or brief retreatment when needed. TMS typically builds over days to weeks and can be sustained with maintenance planning.
On the other hand, ketamine often acts faster. Some patients notice symptom relief within hours or days after the first dose, an advantage when depression is severe or rapidly worsening. Sustaining improvement usually requires completing a series of treatments and transitioning to maintenance dosing at intervals tailored to response.
TMS vs Ketamine/Spravato: Safety, Side Effects and Monitoring
TMS is well tolerated by most patients. Common, mild effects include
- Scalp tenderness
- Tapping sensations
- Facial muscle twitching during stimulation
- Headache that usually fades after the first few sessions
There is no sedation and no systemic side effects such as weight gain or sexual dysfunction. There is no downtime; most people return to normal activities immediately after treatment.
However, ketamine and Spravato can cause short-lived effects during or soon after dosing. These include changes in perception, dissociation, dizziness, nausea, and temporary increases in blood pressure and heart rate. Because of these effects, patients are monitored in clinic and typically need a ride home.
Driving and operating machinery should be avoided until the next day, or as directed by your care team.
TMS vs. Ketamine/Spravato: Who Is a Good Candidate?
TMS is often recommended for adults with mental health disorders who have not responded to one or more forms of treatment or who cannot tolerate side effects. It is a strong option for those with medication sensitivity, comorbid anxiety, or concerns about drug interactions with other medical treatments. Because TMS is non-systemic, it can be considered when minimizing overall medication exposure is a priority.
Ketamine may be considered when rapid relief is important, such as during severe episodes, elevated suicide risk or when multiple prior treatments have not worked. Suitability depends on a careful review of cardiovascular health, blood pressure, medication interactions, and psychiatric history.
People with uncontrolled hypertension, certain neurologic conditions, a history of adverse reactions to dissociative agents, or active substance misuse may need additional precautions or may be better served by another approach.
Age, pregnancy, and medical history influence selection as well. Because TMS does not involve systemic medication, it can be discussed in scenarios where limiting fetal exposure is important, though decisions during pregnancy always require individualized risk-benefit consultation with obstetric and psychiatric clinicians.
What to Expect: Experience, Timeline and Coverage
During a TMS session, you will sit comfortably while a small coil rests against your scalp. Sessions typically last between three and 20 minutes, depending on the protocol used. You can drive yourself to and from appointments and resume normal activities right away. The acute course generally runs five days per week for four to six weeks, with optional tapering or maintenance sessions based on response.
Ketamine and Spravato visits include pre-dose assessments, supervised administration, and post-dose observation. Time in clinic usually ranges from one to two hours or more. Due to ketamine’s side effects, transportation arrangements are required, and driving is avoided until the next day.
Treatment Timelines
Treatment schedules often begin with more frequent visits (for example, twice weekly) and shift to maintenance intervals as symptoms improve.
Timelines for improvement vary. Many TMS patients notice changes within the first two to three weeks, with continued gains toward the end of the course. Ketamine and Spravato may provide relief within hours to days, particularly helpful during crisis periods.
Both approaches can include maintenance strategies, like periodic TMS sessions or scheduled booster doses for Spravato or ketamine, to help sustain progress.
Coverage for TMS and Spravato
Coverage differs by insurer and medical policy. TMS is widely covered by many commercial plans and Medicare for treatment-resistant depression when criteria are met. Spravato is FDA-approved for treatment-resistant depression and for depressive symptoms in adults with major depressive disorder with acute suicidal ideation or behavior; coverage typically follows REMS and plan rules.

TMS vs. Ketamine/Spravato: Which Is Better for Me?
The best choice depends on your goals, timeline, medical history and how you want treatment to fit into your life. If you value a noninvasive option with no systemic medication and minimal disruption to your routine, TMS may be a strong fit.
On the other hand, if you need rapid relief during a severe episode or crisis, Spravato or ketamine may offer faster symptom reduction, with a plan for maintenance dosing to sustain progress.
Some patients consider TMS and Spravato together across different phases of care. An example might be completing a TMS course for foundational improvement and using Spravato for focused booster support during periods of increased symptoms. Others begin with Spravato to stabilize quickly and transition to TMS to build durable gains without ongoing medication.
Our clinicians help you design a plan that aligns with your preferences and clinical needs.
