When antidepressants have not brought enough relief, it can be hard to know what question to ask next. You may feel worn down by medication changes. You may be frustrated by partial improvement. You may wonder whether depression is simply something you have to endure.
It is not a failure to need a more careful conversation. At HavenNexus Advanced Psychiatry & TMS, we meet people in Palm Coast, FL who are looking for a thoughtful next step, not a sales pitch or a one-size-fits-all answer. If antidepressants have not provided sufficient relief, it may be time to review whether your history suggests treatment-resistant depression.
When depression has not responded as hoped
Depression can affect much more than mood. It may change sleep, appetite, focus, motivation, relationships, and your sense of possibility. It can also make daily tasks feel much heavier than they once did. Information on depression and daily functioning recognizes that depression can affect how a person feels, thinks, and manages everyday life (MedlinePlus, n.d.).
The phrase treatment-resistant depression is often used when appropriate antidepressant trials have not produced sufficient relief. It does not mean you are beyond help. It means your treatment history deserves a close look.
We consider which medications you have tried, the dose and length of each trial, and any side effects. We also discuss whether symptoms changed and whether other health or mental health concerns may be involved. Medication management, therapy, sleep, substance use, stress, trauma history, and safety can all shape what comes next. You can explore our broader mental health services as you consider the support that may fit your needs.
What IV ketamine is, and what it is not
Ketamine is a medication long used in anesthesia. It works differently from standard antidepressants and affects NMDA receptors in the brain. A clinical overview of NMDA receptor medicines explains the pharmacology and clinical context of these medications (Davoudian et al., 2020).
In psychiatry, ketamine is used off-label. This means the FDA has not approved ketamine specifically as a treatment for depression. Off-label prescribing is a recognized medical practice. It still calls for a careful assessment, informed consent, monitoring, and a clear discussion of possible benefits, limits, and risks.
For people with treatment-resistant depression, IV ketamine may be one part of a broader care plan. It is not simply an infusion followed by a permanent reset. Depression is often complex. A plan should account for your symptoms, current medications, health history, support system, and follow-up care. Our ketamine therapy page offers a starting point for that conversation.
Ketamine is also not interchangeable with SPRAVATO®. SPRAVATO® is an esketamine nasal spray with its own FDA-approved indications, administration requirements, and monitoring process. If you are comparing options, our SPRAVATO® treatment information can help you understand that distinction before an evaluation.
Why an evaluation comes first
A good evaluation is where the important work begins. Before we recommend IV ketamine for treatment-resistant depression, we want to understand what has happened before and what is happening now.
We may discuss:
- Your symptoms, their severity, and how they affect daily life
- Previous antidepressants, therapy, and other treatments
- Current medications and relevant medical conditions
- Alcohol or substance use that could affect safety or planning
- A personal or family history of bipolar disorder, psychosis, or other psychiatric concerns
- Pregnancy considerations, when relevant
- Current safety concerns, including thoughts of self-harm or suicide
- Your goals, practical supports, and ability to participate in follow-up care
This is not about finding a reason to exclude you. It is about making a sound decision together. We want you to understand why an option may or may not fit your situation. We also want you to know what alternatives remain available if it does not.
Substance use and mental health can overlap in ways that matter for treatment planning. National behavioral health resources emphasize the value of addressing mental health and substance use concerns together when both are present (SAMHSA, n.d.).
Research also shows why we do not assume that one person’s response predicts another’s. A recent review of genetic influences on ketamine response describes the complexity of predicting outcomes across ketamine and related interventions (Franklin et al., 2025). These findings cannot tell us in advance who will benefit. They do reflect an important clinical truth: individual response cannot be promised.
What researchers are still learning
Ketamine has generated interest because it may affect brain signaling in ways that differ from many standard antidepressants. Interest, however, is not certainty. Researchers are still studying why responses vary. They are also studying how brain changes relate to symptoms and which care approaches may fit different people.
For example, a recent study found distinct whole-brain connectivity patterns after ketamine (Moujaes et al., 2024). This research helps build understanding of ketamine’s effects in the brain. It does not mean a scan or a single biological marker can tell us whether ketamine will help a particular person.
That uncertainty is one reason we value direct, unhurried conversations. We will not present IV ketamine as a guaranteed answer. We will help you weigh it against your history and other evidence-based options. One option may include TMS therapy for depression, which is FDA-cleared for depression.
Questions worth bringing to your appointment
You do not need to arrive knowing whether ketamine is right for you. It can help to bring questions that make the conversation more useful:
- Does my treatment history suggest treatment-resistant depression?
- What would make IV ketamine reasonable to consider in my situation?
- Are there medical or psychiatric concerns that need attention first?
- What monitoring is involved during and after treatment?
- How would ketamine fit with my current medications, therapy, and longer-term care?
- What other approaches should I consider if ketamine is not the right fit?
We welcome these questions at HavenNexus Advanced Psychiatry & TMS. They show that you are taking your care seriously. They also help us create a plan that respects both your hope and your need for clear information. When you are ready, you can request an appointment to begin that conversation.
If depression feels urgent right now
If you are in immediate danger or feel unable to stay safe, call 911 or go to the nearest emergency department. You can also call or text 988 for the 988 Suicide & Crisis Lifeline, available 24 hours a day in the United States (988 Suicide & Crisis Lifeline, n.d.).
Depression can narrow your view of what is possible. Reaching out, even when you are unsure what treatment you need, is a meaningful first step.
