When Antidepressants Aren’t Working: Treatment-Resistant Depression Options in New Mexico

You took the medication.

You waited for it to work. Maybe the dose changed. Maybe you tried another one. Maybe therapy helped with some things, but the heaviness, exhaustion, disconnection, or lack of interest never fully lifted.

At some point, it’s reasonable to start asking a different question:

What if the next step isn’t simply another antidepressant?

For people living with depression that hasn’t responded adequately to standard treatment, there are other options. And increasingly, those options include treatments that work very differently from the medications most people try first.

If you’re looking for treatment-resistant depression care in New Mexico, here’s what to know about the paths that may come next.

What Is Treatment-Resistant Depression?

There isn’t a single experience that defines treatment-resistant depression, but the term is generally used when a person with depression has not improved adequately after trying at least two antidepressant treatments.

That can look different from person to person. Maybe neither medication helped. Maybe one helped for a while and then stopped. Maybe there was some improvement, but significant symptoms remain. Or perhaps the medication caused side effects that made continuing treatment difficult.

Whatever the circumstances, “treatment-resistant” does not mean “untreatable.” It means the approach may need to change.

Before Assuming the Depression Is Treatment-Resistant

When depression isn't improving, a good clinical evaluation looks beyond the question of which medication to try next.

A psychiatrist may review whether previous medications were taken at an adequate dose for long enough, whether other health conditions could be contributing to symptoms, and whether the original diagnosis still fits. Life circumstances, substance use, other medications, and co-occurring mental health conditions can also affect how someone responds to treatment.

That evaluation matters because persistent depression symptoms don't always mean the same thing.

The goal is to understand why the current approach isn't getting you where you need to go before deciding what to change.

Option 1: Adjusting the Medication Strategy

Sometimes the next step is still medication—but not simply starting over.

A psychiatrist might change the dose, switch to a different antidepressant, or combine an antidepressant with another medication intended to strengthen its effect. NIMH notes that augmentation strategies can include adding certain antipsychotic or anticonvulsant medications to an antidepressant for treatment-resistant depression.

There are many possible medication strategies, and the right one depends on factors such as your previous response, side effects, other health conditions, and the medications you've already tried. For some people, medication adjustments eventually make a meaningful difference. For others, repeated trials begin to feel like diminishing returns—and that is often when conversations about treatments such as TMS or ketamine begin.

Option 2: Psychotherapy

Medication resistance does not necessarily mean psychotherapy has nothing more to offer.

Different forms of therapy address different aspects of depression, and sometimes changing the therapeutic approach matters just as much as changing a medication.

Psychotherapy can help people identify patterns of thought and behavior, develop coping strategies, work with difficult relationships or experiences, and gradually reconnect with activities and parts of life that depression has narrowed. NIMH continues to recommend psychotherapy, medication, or a combination of the two as foundational approaches to depression treatment.

For many people with treatment-resistant depression, psychotherapy remains part of the treatment plan even when another intervention is added. The question isn't necessarily therapy or something else. It may be what combination gives you the best chance of improving?

Option 3: Transcranial Magnetic Stimulation (TMS)

TMS is one of the major non-medication options for people whose depression hasn't responded adequately to antidepressants. Transcranial magnetic stimulation uses repeated magnetic pulses to stimulate targeted areas of the brain involved in depression.

The treatment is noninvasive. There is no surgery, anesthesia, or implanted device, and patients remain awake during the session. The FDA first cleared an rTMS device for depression in 2008 for adults who had not responded adequately to an antidepressant. Treatment usually involves a series of appointments over several weeks.

One of the practical differences between TMS and many other interventional treatments is what happens afterward: because TMS does not involve sedation, patients can generally return to their normal activities after a session.

TMS may be especially worth discussing if you've tried multiple antidepressants without adequate improvement, you've had difficulty tolerating medication side effects, or you're interested in exploring a non-medication treatment.

It isn't appropriate for everyone, and a clinical evaluation is necessary to determine whether it makes sense for you.

Option 4: Ketamine and Esketamine

Ketamine-based treatments have also become an important part of the conversation around treatment-resistant depression.

There are two terms you may encounter.

IV ketamine is an anesthetic medication that some clinicians use off-label at lower doses to treat depression.

Esketamine, sold as Spravato, is a related medication administered as a nasal spray in a supervised medical setting. The FDA has approved Spravato for treatment-resistant depression in adults.

One characteristic that distinguishes ketamine-based treatment from many traditional antidepressants is its potential speed. NIMH notes that esketamine can produce improvement within hours for some patients.

The treatment experience is also different from TMS.

Ketamine and esketamine can temporarily affect perception and awareness. Spravato treatment requires medical supervision and a period of observation after administration because of risks including sedation, dissociation, changes in blood pressure, and respiratory effects.

Option 5: Electroconvulsive Therapy (ECT)

ECT remains another important treatment for severe or treatment-resistant depression.

Modern ECT is performed under general anesthesia. A carefully controlled electrical current produces a brief seizure, which can lead to significant improvement in severe depression. It may be considered when other treatments haven't worked or when a rapid response is particularly important—for example, in some cases involving severe suicidality, catatonia, or inability to eat or drink.

ECT is very different from the way it is often depicted in popular culture.

At the same time, it is a more medically intensive treatment than TMS. It requires anesthesia and can cause temporary confusion and memory problems, among other side effects. For some patients with severe depression, those tradeoffs may be appropriate. For others, a less intensive option such as TMS may be considered earlier.

So How Do You Decide What to Try Next?

When you've already gone through several treatments, it can be tempting to search for the one option that is simply “best.” Depression rarely works that neatly.

The most appropriate next step depends on questions such as:

• What treatments have you already tried, and for how long?

• Did they help at all?

• What side effects have you experienced?

• How severe are your symptoms right now?

• Are you looking for a medication or a non-medication approach?

• Do you have medical conditions that make certain treatments less appropriate?

• How much time can you realistically devote to treatment?

• How important is being able to drive or return to work immediately after appointments?

• What does your insurance cover?

Your preferences matter too. NIMH emphasizes that depression treatment should take into account a person's needs, preferences, and medical situation—not simply the diagnosis itself.

When Is It Time to Look Beyond Another Antidepressant?

There isn't one exact moment.

But if you've gone through multiple adequate medication trials and continue to experience significant depression symptoms, it is reasonable to ask your provider whether you're dealing with treatment-resistant depression and whether a different treatment approach should be considered.

That conversation doesn't obligate you to start TMS, ketamine, or any other treatment. It simply expands the conversation.

Instead of asking: “Which antidepressant should I try next?” you can begin asking: “What are all of my treatment options now?”

That distinction can matter.

Exploring Treatment-Resistant Depression Care in Santa Fe and New Mexico

Access to specialized psychiatric treatment hasn't always been easy for people living outside major metropolitan medical centers.

If you live in Santa Fe, Albuquerque, or elsewhere in New Mexico, the logistics of treatment are part of the decision too. Some options require frequent visits. Others require monitoring or arranging transportation home. Insurance coverage can also differ significantly depending on the treatment and your individual plan.

Those are practical questions—but they are important ones. A treatment only works as an option if you can realistically access and complete it.

At Anew TMS in Santa Fe, we help patients understand whether TMS may be an appropriate next step when depression hasn't improved enough with previous treatment. The first conversation isn't about convincing you to choose TMS. It's about understanding what you've already tried, how depression is affecting your life now, and whether this particular treatment makes sense within the larger picture of your care.

You Still Have Options

Repeated treatment attempts can be exhausting. When one medication after another doesn't create the change you hoped for, it's easy for disappointment with treatment to start feeling like hopelessness about depression itself. Those aren't the same thing. A treatment not working is information. And sometimes that information tells your care team that it's time to approach depression differently.
