If you're struggling with treatment-resistant depression, you may be weighing your options between two innovative treatments: Spravato (esketamine) and TMS (Transcranial Magnetic Stimulation). Both are FDA-approved and can provide relief when traditional antidepressants haven't worked—but they work very differently. Here's everything you need to know to make an informed choice.
Understanding the Treatments
What Is Spravato?
Spravato (esketamine) is an FDA-approved nasal spray derived from ketamine. It works by targeting the glutamate system—the brain's primary excitatory neurotransmitter—to rapidly create new neural connections. This mechanism is fundamentally different from traditional antidepressants that target serotonin, norepinephrine, or dopamine.
Spravato must be administered in a certified healthcare setting under the FDA's REMS (Risk Evaluation and Mitigation Strategy) program. Patients self-administer the nasal spray and are monitored for 2 hours afterward.
What Is TMS Therapy?
TMS (Transcranial Magnetic Stimulation) uses magnetic pulses to stimulate nerve cells in the brain's prefrontal cortex—the region associated with mood regulation. It's a non-invasive, non-drug treatment that doesn't require anesthesia or sedation.
During TMS, a magnetic coil is placed against the scalp, delivering targeted pulses. Standard treatment involves daily sessions (typically 20-30 minutes) five days a week for 4-6 weeks.

| Cost (Without Insurance) | $600-900 per session | $300-500 per session ($6,000-15,000 full course) |
| Insurance Coverage | Often covered; $20-150 copay typical | Often covered; varies by plan |
| Can Drive After? | No - must arrange ride home | Yes - can drive immediately |
How Do They Work? Understanding the Mechanisms
Spravato's Mechanism
- • Blocks NMDA receptors in the glutamate system
- • Triggers rapid release of growth factors (BDNF)
- • Promotes synaptogenesis (new neural connections)
- • Works within hours to days, not weeks
- • Acts on a completely different pathway than SSRIs/SNRIs
TMS's Mechanism
- • Generates magnetic fields that penetrate the skull
- • Induces electrical currents in targeted brain regions
- • Activates underactive areas of the prefrontal cortex
- • Gradually normalizes neural activity over weeks
- • No systemic drug effects—targeted brain stimulation only
"The key difference is speed and approach. Spravato creates rapid chemical changes that can provide relief quickly, while TMS gradually retrains brain circuits over time. Both can be transformative—they just work differently."
Who Is Each Treatment Best For?
Spravato May Be Best For You If:
- You need faster relief — Spravato can work within days to weeks, not months
- You're in crisis or have suicidal thoughts — FDA-approved specifically for MDD with acute suicidal ideation
- You can't commit to daily treatments — Spravato is 2x/week initially, then less frequent
- Traditional antidepressants haven't worked — Works through a completely different mechanism
- You have good insurance coverage — Most plans cover Spravato with manageable copays
- You're comfortable with temporary dissociative effects — These are monitored and resolve within 2 hours
TMS May Be Best For You If:
- You prefer a non-drug approach — TMS uses no medications or chemicals
- You want to avoid systemic side effects — Effects are localized to the brain
- You need to drive yourself to appointments — No post-treatment impairment
- You can commit to daily sessions for 4-6 weeks — The intensive schedule is key to success
- You have contraindications to Spravato — Such as uncontrolled hypertension or certain vascular conditions
- You want longer-lasting effects between treatments — TMS effects often persist 6-12 months
Side Effects Comparison
Spravato Side Effects
Most resolve within 2 hours of treatment:
- Dissociation (feeling detached) — 61%
- Dizziness — 29%
- Nausea — 28%
- Sedation — 23%
- Headache — 20%
- Temporary blood pressure increase
TMS Side Effects
Generally milder, may improve over treatment course:
- Scalp discomfort/pain at treatment site — 50%
- Headache — 30%
- Facial muscle twitching during treatment
- Lightheadedness — rare
- Seizure — very rare (<0.1%)
Insurance Coverage & Costs
Both treatments are often covered by insurance, but coverage details vary significantly:
Spravato Insurance Coverage
- • Most commercial insurance plans cover Spravato with prior authorization
- • Medicare Part D typically provides coverage
- • Many Medicaid plans cover treatment
- • Typical copays: $20-150 per session with insurance
- • Without insurance: $600-900 per session
- • Manufacturer assistance programs available for eligible patients
TMS Insurance Coverage
- • Many commercial insurers cover TMS after failed antidepressant trials
- • Medicare coverage varies by region and specific plan
- • Prior authorization typically required
- • Full course cost without insurance: $6,000-15,000 (30-36 sessions)
- • Coverage requirements often stricter than Spravato

Frequently Asked Questions
Can you do Spravato and TMS at the same time?
Yes, some patients benefit from combining Spravato and TMS therapy. They work through different mechanisms—Spravato affects glutamate neurotransmission while TMS uses magnetic stimulation to activate brain circuits. However, combining treatments should only be done under close psychiatric supervision. At Next Step Psychiatry, we can help determine if a combination approach might benefit your specific situation.
How fast does Spravato work compared to TMS?
Spravato typically works faster. Many patients notice improvement within the first 1-4 weeks, with some experiencing relief after their first few sessions. TMS usually takes 4-6 weeks of daily treatments before significant improvement is seen. For patients in crisis or those who need faster relief, Spravato's rapid onset can be a significant advantage.
Which is more effective: Spravato or TMS?
Both treatments show strong effectiveness for treatment-resistant depression, with response rates of 50-70% for Spravato and 50-60% for TMS. The "better" treatment depends on individual factors. Spravato may be preferred for faster relief and chemical-based depression, while TMS may suit those who prefer non-drug approaches. Some patients who don't respond to one may respond to the other.
Does insurance cover Spravato and TMS?
Yes, most insurance plans cover both treatments when medically necessary. Spravato is FDA-approved for treatment-resistant depression and is covered by most commercial insurance, Medicare Part D, and many Medicaid plans—often with copays of $20-150 per session. TMS is also FDA-cleared and covered by many insurers, though coverage varies more. At Next Step Psychiatry, we specialize in obtaining Spravato insurance authorization.
What are the main side effects of Spravato vs TMS?
Spravato's common side effects include temporary dissociation, dizziness, nausea, and sedation—these typically resolve within 2 hours and patients are monitored during this time. TMS's main side effects are scalp discomfort and headaches during treatment, with rare risk of seizures. TMS has fewer systemic side effects since it's non-drug, while Spravato's effects are more noticeable but temporary.
How long do the effects of Spravato and TMS last?
Both treatments can provide lasting relief with proper maintenance. Spravato effects are maintained with ongoing sessions—typically weekly during the first month, then weekly or biweekly. TMS effects often last 6-12 months after an initial treatment course, with some patients needing periodic "booster" sessions. Both require an individualized maintenance plan based on your response.
Who should NOT get Spravato or TMS?
Spravato is not recommended for those with uncontrolled high blood pressure, aneurysms, or history of certain substance abuse. TMS is contraindicated for people with metal implants in or near the head (excluding dental work), pacemakers, or history of seizures. Both require evaluation to determine candidacy. A psychiatric consultation can help determine which treatment is safe for you.
