For many people living with depression, finding the right treatment can feel like a long and uncertain journey. Antidepressant medications have been the standard of care for decades, but they don’t work for everyone. In recent years, Transcranial Magnetic Stimulation (TMS) has emerged as a promising, non-drug alternative that helps many patients achieve relief when medications fall short.
At Cantera Psychiatry, we take a holistic approach to mental health. We specialize in both medication management and TMS therapy for depression, tailoring every treatment plan to the individual. If you’re in San Antonio, we proudly offer FDA-approved, insurance-covered TMS therapy.
Understanding how these treatments differ can help you make a confident, informed decision about your mental health care. Let’s explore the key distinctions between TMS and traditional medication.
How Antidepressant Medication Works
Antidepressants target the brain’s chemical messengers, known as neurotransmitters, such as serotonin, norepinephrine, and dopamine. These medications help restore balance to brain chemistry, improving mood and energy levels over time.
There are several common classes of antidepressants, including:
- SSRIs (Selective Serotonin Reuptake Inhibitors): e.g., Prozac, Zoloft, Lexapro
- SNRIs (Serotonin-Norepinephrine Reuptake Inhibitors): e.g., Effexor, Cymbalta
- Tricyclics and MAOIs: older options often used when newer medications are ineffective
For many patients, these medications can significantly improve symptoms of depression. However, they typically require several weeks to take effect, and finding the right medication or dose often involves a period of trial and adjustment.
Common side effects may include nausea, sleep disturbances, sexual dysfunction, or weight changes. While some side effects improve over time, others may persist, leading some patients to seek non-medication alternatives.
How TMS Therapy Works
TMS (Transcranial Magnetic Stimulation) uses gentle, targeted magnetic pulses to stimulate areas of the brain involved in mood regulation, specifically the left dorsolateral prefrontal cortex, which tends to be underactive in people with depression.
Unlike medication, TMS does not rely on altering brain chemistry through systemic drug use. Instead, it helps the brain “reconnect” key neural pathways that regulate mood and emotional balance.
At Cantera Psychiatry in San Antonio, we use the MagVita TMS system, an advanced, highly focused device delivering MRI-strength magnetic pulses with precision. This is the only depression treatment with virtually no systemic side effects, and the only contraindication is having metal implants in the upper body or head.
What a session looks like:
- You sit comfortably on a chair for 20–40 minutes
- An 8-shaped coil rests over the targeted brain region
- Pulses are delivered while you remain awake and alert
- No downtime patients can drive themselves to and from the appointment
TMS is FDA-approved, drug-free, and covered by most major insurances. It’s an especially effective option for individuals whose depression has not improved with medication.
Comparing Effectiveness: What the Research Shows
While antidepressant medications remain effective for many people, studies show that up to one-third of patients don’t respond adequately to their first medication, and with each new trial, the chance of remission decreases.
By contrast, TMS therapy has demonstrated treatment response rates around 60–75%, twice as effective as oral medications alone, with many patients achieving lasting improvement even after multiple failed medication trials.
A 2024 study published in the American Journal of Psychiatry found that patients receiving TMS achieved significantly higher remission rates (27%) compared to those who switched medications (4.9%) after two or more failed trials.
This data suggests that TMS may not only be effective for difficult-to-treat depression but could also be considered earlier in the treatment plan, rather than as a last resort.
Comparing Side Effects and Tolerability
| Aspect | TMS Therapy | Antidepressant Medication |
| Invasiveness | Non-invasive | Oral or sometimes injectable |
| Common Side Effects | Mild scalp discomfort or headache | Nausea, weight gain, fatigue, sexual dysfunction |
| Sedation or Anesthesia | None required | Not applicable |
| Cognitive Effects | None | Some patients experience mental “fog” |
| Discontinuation Symptoms | None | Possible withdrawal symptoms if stopped abruptly |
TMS is generally well tolerated, with minimal side effects and no downtime, making it a strong option for patients who can’t tolerate or prefer to avoid medication-related side effects.
When Medication Management Is Effective
Medication is often a good first-line treatment for mild to moderate depression, especially for individuals who have not yet tried an antidepressant or have responded well in the past.
Our clinicians monitor medication effectiveness, side effects, and progress closely, adjusting your plan as needed. For many patients, medication works best when combined with therapy and lifestyle adjustments.
When TMS Might Be the Better Fit
TMS may be recommended if:
- You’ve tried two or more antidepressants without adequate relief
- You experience intolerable side effects from medications
- You prefer a non-drug, non-invasive treatment
- You want to reduce long-term reliance on medication
TMS directly targets the brain’s mood regulation centers, helping “reset” neural activity and restore emotional balance, without affecting the rest of the body.
For San Antonio residents specifically, we offer easy access to FDA-approved, insurance-covered TMS therapy with proven effectiveness and no downtime.
Combination Therapy: The Best of Both Worlds
For some individuals, combining TMS with medication produces the best outcomes. Research supports using both together, as TMS can enhance the brain’s responsiveness to antidepressants and help sustain remission longer.
At Cantera Psychiatry, we personalize every treatment plan. Whether that means starting with TMS, continuing with medication, or combining both, our goal is to help each patient achieve lasting relief and a restored quality of life.
Ready to Begin Your TMS Journey?
Both TMS therapy and antidepressant medication are valuable tools for treating depression. The right choice depends on your medical history, response to past treatments, and personal preferences.
If you’re in San Antonio and struggling with depression that hasn’t responded to medication, TMS may be the solution you’ve been searching for. This non-invasive, FDA-approved treatment uses targeted magnetic pulses to stimulate the brain’s mood-regulation centers, offering effective relief with virtually no side effects. Schedule a consultation today to explore how TMS or medication may help you reclaim balance and well-being.
