SAINT® TMS vs Antidepressant Medication
SAINT® TMS and antidepressant medication both treat depression, but through entirely different mechanisms. Antidepressants are chemicals that affect neurotransmitters throughout the body — they can cause systemic side effects like weight gain, sexual dysfunction, and GI issues. SAINT® uses magnetic pulses to stimulate a specific brain region — it introduces no chemical into the body and causes no systemic side effects. SAINT® is FDA-cleared for adults whose depression hasn't improved on antidepressants. The two treatments can be used together. Neither guarantees results, and the appropriate choice depends on clinical circumstances.
Key takeaways
- Antidepressants are chemicals; SAINT® is magnetic brain stimulation.
- Antidepressants cause systemic side effects; SAINT® does not.
- SAINT® is FDA-cleared for depression that hasn't improved on medication.
- The two can be used together.
- Neither guarantees results.
How They Work
Antidepressant medication (SSRIs, SNRIs, etc.) works by altering neurotransmitter levels — serotonin, norepinephrine, dopamine — throughout the brain and body. These chemicals affect many systems, which is why antidepressants can cause side effects like weight gain, sexual dysfunction, insomnia, and GI issues. SAINT® TMS uses magnetic pulses to stimulate a specific brain region (the left dorsolateral prefrontal cortex) involved in mood regulation. It introduces no chemical into the body and affects only the targeted brain region.
Key Differences
| Feature | SAINT® TMS | Antidepressants |
|---|---|---|
| Mechanism | Magnetic brain stimulation | Chemical neurotransmitter modulation |
| FDA status | FDA-cleared (K220177) | FDA-approved |
| Treatment duration | 5 days | Ongoing (months to years) |
| Systemic side effects | None | Weight gain, sexual dysfunction, GI issues |
| Common side effects | Headache, scalp discomfort | Varies by medication |
| Onset | Days (in trials) | 2–6 weeks |
| Discontinuation | No withdrawal | Possible discontinuation syndrome |
| Medication required | No | Yes (daily pill) |
Can They Be Used Together?
Yes. Many patients continue antidepressant medication during and after SAINT®. Combining approaches is often more effective than any single treatment. Whether to continue, adjust, or stop medication is a clinical decision made by your psychiatrist. Do not stop medication on your own — abrupt discontinuation can cause withdrawal symptoms and increase relapse risk.
Understanding SAINT® TMS: How It Works & What to Expect
SAINT® is an FDA-cleared treatment for adults with major depressive disorder who have not improved on antidepressants in the current episode. These videos explain how it works and how it differs from conventional TMS.
SAINT® is an FDA-cleared, fMRI-guided form of TMS developed at Stanford. Most patients complete treatment in one week — not the six weeks standard TMS requires.

Is SAINT® TMS Right for You?
Tried antidepressants without enough relief? SAINT® TMS is an FDA-cleared, fMRI-guided treatment for adults with major depressive disorder who have not improved enough with antidepressant medication.
SAINT® uses a personalized brain target and delivers treatment over five consecutive days. It differs from standard TMS in its targeting approach, treatment schedule, and research background. In a small randomized trial, 11 of 14 people receiving active treatment reached remission at the four-week assessment, compared with 2 of 15 receiving sham treatment. Results vary, and a five-day treatment course does not guarantee remission in five days.
How SAINT® Works and How It Differs From Conventional TMS
SAINT® is an FDA-cleared treatment for adults with major depressive disorder who have not improved on antidepressants in the current episode. This video explains how it works, and how it differs from conventional TMS.
Conventional TMS usually means about 30 visits over 6 to 9 weeks. SAINT is five visits over five days.
What makes it different: SAINT is the only FDA-cleared depression treatment that uses an fMRI scan to personalize the stimulation target to your individual brain. A 45-minute scan maps your brain and identifies the specific circuit linked to depression. Treatment is then delivered as ten 10-minute sessions per day, with 50-minute breaks between them, across five consecutive days.
In clinical trials, 79% of participants reached remission, with an average of 2.6 days to remission. SAINT is generally well tolerated; the most common side effects reported were mild headache and temporary scalp discomfort at the treatment site.

Frequently Asked Questions
Is SAINT TMS better than antidepressants?
Not universally. SAINT® works through a different mechanism and doesn't cause systemic side effects. Antidepressants are effective for many people and are often covered by insurance. SAINT® is FDA-cleared for depression that hasn't improved on medication. The appropriate choice depends on your history and clinical circumstances.
Can I stop antidepressants if I get SAINT TMS?
Not on your own. Stopping abruptly can cause discontinuation symptoms and increase relapse risk. Talk to your prescriber about a gradual taper. Many patients continue medication during and after SAINT®. Combining approaches is often more effective.
Does SAINT TMS have fewer side effects than antidepressants?
SAINT® doesn't cause systemic side effects like weight gain, sexual dysfunction, or GI issues because it introduces no chemical into the body. Its side effects (headache, scalp discomfort) are localized and usually mild. However, individual experiences vary.
