Approximately 30 percent of people with major depressive disorder do not achieve adequate symptom relief after two or more antidepressant trials conducted at therapeutic doses and durations—a reality that the psychiatric community formally recognizes as treatment-resistant depression (TRD). The frustration of watching medication after medication fail can erode hope in ways that go far beyond the original diagnosis, and many patients in this situation assume they have simply exhausted their options. At Thrive Center for Health, we work specifically with patients who have reached that point, and we want to be direct: there are meaningful options available even when the standard path has not worked.
Understanding Why Standard Antidepressants Fall Short
Treatment-resistant depression is not a character flaw, a failure of willpower, or a sign that the situation is hopeless. It is a recognized clinical phenomenon driven by complex neurobiological factors that conventional antidepressants—primarily SSRIs and SNRIs—may not adequately address for every patient. Understanding why standard medications do not work for some people is important context for understanding why interventional approaches exist and why they are increasingly integrated into clinical guidelines for this population.
SSRIs and SNRIs primarily work by modulating the serotonin or norepinephrine systems in the brain. For many patients, this is sufficient to achieve remission. For those with TRD, however, the depressive pathology may involve dysregulation in other neural systems, including the glutamate system, which conventional antidepressants do not directly target. To better understand how these two approaches compare, see our overview of ketamine vs antidepressants: key differences. Ketamine acts as an NMDA receptor antagonist, rapidly influencing glutamate transmission and triggering neuroplastic changes that may restore function in circuits associated with mood regulation. This is why ketamine can produce antidepressant effects within hours rather than the weeks it typically takes for SSRIs to work—a clinically meaningful distinction for patients in severe distress.
IV Ketamine Therapy at Our Grand Rapids Clinic
At our Grand Rapids clinic, we offer unique depression treatment as a primary intervention for patients with treatment-resistant depression. IV ketamine infusions are administered in a comfortable private treatment room with continuous clinical monitoring throughout. Each session typically lasts approximately forty to sixty minutes, and most patients describe the experience as manageable and, for many, surprisingly meaningful. We prepare every patient thoroughly before their first infusion so that they arrive informed and as comfortable as possible with what to expect.
A separate but complementary option we offer is ketamine-assisted psychotherapy (KAP), which pairs the neuroplasticity window created by ketamine with structured therapeutic support. For patients whose depression is intertwined with unprocessed trauma, grief, or deeply entrenched patterns of thought, this integration approach may offer benefits that go beyond what either treatment provides in isolation. Our clinical team works with each patient to determine which approach best fits their goals and history.
A Clinic Built for Complex Treatment Histories
One barrier that many patients with TRD have encountered long before arriving at our door is dismissal—the sense that their struggle was not believed or taken seriously by previous providers. We built Thrive Center for Health specifically for patients with this background. Our intake process is designed to be thorough and non-judgmental, and our clinical culture centers around five values: compassionate, approachable, inspiring, dedicated, and authentic. Every patient who walks through our doors brings years of experience navigating a system that was not designed for them, and we take that history seriously.
The second barrier we consistently address is cost and logistics. IV ketamine is not universally covered by insurance, and we understand that this reality weighs heavily on patients who may already be dealing with significant financial strain from years of previous treatments. We have transparent conversations about cost from the very first intake consultation, and we work with patients to identify the most accessible path to care. We also understand that managing a chronic condition alongside work, family, and daily life requires flexibility—and we do our best to accommodate that reality in how we schedule and structure care.
Medication management is another dimension of care we offer for patients navigating TRD. For some patients, the path forward involves ketamine as a bridge treatment combined with thoughtful reassessment and adjustment of their overall psychiatric medication regimen. Our team brings expertise in both interventional and pharmacological approaches, and we coordinate care holistically rather than treating each modality in isolation.
Treating the Whole Person, Not Just the Diagnosis
We also want to be honest about what treatment-resistant depression looks like in the broader context of our patient population. Many of the patients we see carry co-occurring diagnoses: PTSD, anxiety disorders, obsessive-compulsive disorder, and in some cases chronic pain conditions like fibromyalgia, CRPS, or migraines. These conditions often interact in ways that make depression harder to treat in isolation, and our approach reflects that complexity. For patients whose depression overlaps with chronic pain, our post on the psychobiology of chronic pain offers helpful context on how these systems are intertwined. We do not treat a diagnosis—we treat a person.
Results vary by individual. Some patients experience significant relief after their initial ketamine series; others require ongoing maintenance sessions or additional therapeutic support. We never guarantee outcomes, because doing so would not be honest—and honesty is the foundation on which we have built every aspect of care at Thrive Center for Health. Discuss with your provider what a realistic and personalized treatment plan might look like for your specific situation.
Frequently Asked Questions
How is treatment-resistant depression diagnosed?
Treatment-resistant depression is generally defined as a major depressive episode that does not respond adequately to at least two antidepressant medications tried at appropriate doses and durations. Some clinicians use more stringent criteria requiring failure of additional medication classes. A thorough evaluation by a qualified psychiatric provider is necessary to establish this diagnosis and determine appropriate next steps.
Is IV ketamine effective for treatment-resistant depression?
A substantial and growing body of clinical research supports the effectiveness of IV ketamine for treatment-resistant depression, with studies showing rapid symptom reduction in many patients who have not responded to conventional antidepressants. Results vary by individual, and ketamine’s use for depression is off-label. A full clinical evaluation will help determine whether this is an appropriate option for your situation.
How long do the effects of ketamine last for depression?
The duration of benefit varies considerably from one patient to another. Some patients experience sustained relief after an initial infusion series; others find that periodic maintenance sessions are needed to preserve the gains they have achieved. We discuss with every patient what ongoing care might realistically look like based on their response to initial treatment.
Do I need a referral to be seen at Thrive Center for Health?
Most patients contact us directly, and a formal referral is not required to schedule an initial consultation. We do recommend that patients have documentation of their prior treatment history, including previous medications and therapeutic interventions, as this helps us conduct the most thorough evaluation possible.
Can ketamine be combined with my current psychiatric medications?
In many cases, yes—but a detailed medication review is an essential part of the evaluation process. Certain medications may interact with ketamine or affect its safety profile. Always discuss with your provider your complete list of current medications, supplements, and substances before beginning ketamine treatment.
