Condition
Treatment-Resistant Depression Treatment in Texas
If two or more antidepressants haven’t worked, you may have treatment-resistant depression — but that describes what’s been tried, not a dead end. Real options remain: switching, augmentation, TMS, and esketamine. Many people who didn’t respond to the first medications respond to a thoughtful next step.

What counts as treatment-resistant?
Treatment-resistant depression is usually defined as major depression that hasn’t improved after adequate trials of two or more antidepressants from different classes — a reasonable dose, taken long enough (often about six weeks each). It’s common: roughly 15–30% of people don’t respond adequately to their first treatments. That’s a signal to change the approach, not to give up.
First, a careful re-look
Before escalating, a good evaluation revisits the basics: is the diagnosis right, were doses and durations adequate, is there an untreated condition (like a thyroid problem, bipolar spectrum, or substance use) muddying the picture, and are sleep, medical, and life factors being addressed? Sometimes the “next step” is fixing one of those.
Next-step options
- Switch to a different antidepressant, often from another class
- Augment — add a second medication (for example a second-generation antipsychotic proven as an add-on) alongside the antidepressant
- TMS (transcranial magnetic stimulation) — a non-invasive, FDA-approved outpatient treatment using magnetic pulses; no anesthesia
- Esketamine (intranasal, used with an antidepressant) — FDA-approved for TRD
Which path fits depends on your history, preferences, and safety considerations — decided with your prescriber, with close follow-up. This page is educational and doesn’t include dosing.
Medication guides
The antidepressants often tried first
These are common first-line antidepressants — the kind of medications a TRD evaluation reviews before moving to a switch, augmentation, TMS, or esketamine. Each guide explains what it treats, how it works, and side effects. Your prescriber decides what’s right for you.
Frequently asked questions
What is treatment-resistant depression?
Treatment-resistant depression (TRD) is most often defined as major depression that hasn't improved after adequate trials of two or more antidepressants from different classes — meaning a reasonable dose taken for long enough (often about six weeks each). It doesn't mean your depression can't be treated; it means the first-line approach needs to change.
How common is it?
It's common — roughly 15% to 30% of people treated with antidepressants don't respond adequately to their first treatments. Because TRD carries a higher risk of relapse and of serious outcomes, it's worth escalating care rather than giving up.
What are the next-step options?
Common strategies include switching to a different antidepressant, augmenting (adding a second medication — for example a second-generation antipsychotic proven as an add-on), and non-medication or newer options like transcranial magnetic stimulation (TMS) and intranasal esketamine (used alongside an antidepressant). Both TMS and esketamine are FDA-approved for TRD. The right path depends on your history.
What is TMS?
Transcranial magnetic stimulation (TMS) is a non-invasive, FDA-approved treatment that uses magnetic pulses to stimulate mood-related areas of the brain. It's done in a series of outpatient sessions and doesn't require anesthesia or sedation. A clinician can tell you whether you're a candidate.
Is there hope if nothing has worked so far?
Yes. 'Treatment-resistant' describes what's been tried, not a dead end. Many people who didn't respond to the first one or two medications do respond to a thoughtful next step — a switch, an augmentation, TMS, or esketamine. A careful re-evaluation often finds a path forward.
