Antidepressants are often an important part of depression treatment, but they do not work equally well for everyone. Some people experience only partial improvement, while others continue to have significant symptoms despite trying more than one medication.



When depression remains difficult to treat, a psychiatrist may consider additional options such as transcranial magnetic stimulation, or TMS. TMS is a noninvasive treatment that uses magnetic pulses to stimulate areas of the brain involved in mood regulation. It is commonly considered when standard approaches have not provided enough relief.

One Medication Failure Does Not Mean Treatment Has Failed

Not responding to the first antidepressant does not automatically mean someone has treatment-resistant depression.

Different medications work through different mechanisms, and people vary considerably in how they respond. A psychiatrist may first evaluate whether the medication was taken for an adequate amount of time, whether the dose was appropriate, whether side effects limited treatment, and whether another medication or combination may be reasonable.

The broader diagnosis may also need to be reviewed. Other medical or psychiatric conditions can sometimes affect how depression responds to treatment.

When TMS Enters the Conversation

TMS may become an option when depression symptoms continue despite appropriate medication treatment.

During TMS, an electromagnetic coil is positioned against the scalp. Magnetic pulses stimulate nerve cells in targeted areas of the brain associated with depression and mood regulation. Unlike surgery or implanted brain stimulation, the treatment does not require an incision.

Treatment is typically delivered through a series of sessions rather than a single appointment. The exact protocol depends on the TMS system, treatment plan, and individual patient.

TMS Works Differently From Medication

Antidepressants circulate throughout the body and affect chemical signaling in the brain.

TMS takes a more targeted approach by applying magnetic stimulation to specific brain regions. This difference can make TMS worth considering when medications have not produced an adequate response or when medication-related side effects have complicated treatment.

TMS does not require patients to stop all psychiatric medication automatically. Medication management and TMS may sometimes be used together, depending on the individual treatment plan.

Treatment Does Not Require Anesthesia

Another important feature of TMS is that patients remain awake during treatment.

There is no general anesthesia, and patients typically return to normal activities after a session. This makes TMS very different from electroconvulsive therapy, which requires anesthesia and produces a controlled seizure.

For people balancing treatment with work, family responsibilities, or other daily obligations, the outpatient nature of TMS can be an important consideration.

A Psychiatric Evaluation Still Comes First

TMS is not appropriate simply because someone feels that an antidepressant “did not work.”

A psychiatrist should review previous treatment trials, current symptoms, diagnosis, medical history, medications, and other factors before recommending an advanced treatment.

That evaluation may reveal that a medication needs more time, that a dosage adjustment is appropriate, or that another treatment strategy should be considered.

For some patients, however, the evaluation may show that continuing to cycle through standard medication approaches is unlikely to be the only reasonable next step.

Partial Improvement Can Still Matter

Depression treatment is not always an all-or-nothing process.

Someone may experience better sleep but continue to struggle with motivation. Another patient may feel less sadness but still have significant fatigue, concentration problems, or loss of interest in activities.

These remaining symptoms matter when evaluating whether treatment has been adequate.

The goal is not simply to determine whether medication produced any improvement. It is to understand how much depression is still affecting everyday functioning and whether another treatment could reasonably be considered.

Expanding the Treatment Plan

When antidepressants have not worked well enough, the next step should be based on a careful review rather than frustration or guesswork. Medication adjustments, psychotherapy, TMS, SPRAVATO®, and other evidence-based strategies may all be considered depending on the diagnosis and individual circumstances.

Apex Interventional Psychiatry provides comprehensive psychiatric evaluation, medication management, TMS, and SPRAVATO® treatment for appropriate patients. If depression symptoms continue despite previous antidepressant treatment, contact Apex Interventional Psychiatry to discuss whether TMS or another treatment approach may fit into a more individualized plan.
