Ketamine Therapy for Treatment Resistant Depression in Charlotte
Treatment resistant depression is one of the most common reasons people reach out to us. If you have taken two or more antidepressants without lasting relief, the problem is not a lack of effort on your part. It often means your depression has not responded to the serotonin focused mechanism that most first line drugs rely on. Ketamine therapy at our clinic in Charlotte, NC takes a different route, and every patient begins with a physician consultation to confirm whether it is appropriate.
What Treatment Resistant Depression Means
Clinicians generally use the term treatment resistant depression when a person has not responded adequately to at least two antidepressants, each taken at a sufficient dose for a sufficient duration. The definition varies somewhat across research groups, but the lived experience is consistent: the medications that are supposed to help simply have not. If that sounds familiar, our broader page on ketamine therapy for depression provides additional context that pairs well with this one.
When SSRIs Have Not Worked
SSRIs and SNRIs raise the availability of serotonin and related neurotransmitters. For people with treatment resistant depression, that approach has already been tested and found wanting. Continuing to cycle through medications in the same class can feel discouraging. The value of ketamine is that it does not depend on the pathway that has already let you down.
A Different Mechanism
Ketamine modulates NMDA receptors within the glutamate system, the brain’s main excitatory signaling network. Research suggests this prompts a cascade that supports synaptic plasticity, the brain’s ability to build new connections. Our overview of how ketamine therapy works explains this in plain language and links to the underlying science.
What the Evidence Shows
- A National Institute of Mental Health trial reported rapid, significant improvement in participants with treatment resistant depression after a single infusion (Zarate et al., 2006).
- A two site randomized controlled trial found that a meaningful share of participants with treatment resistant depression responded to ketamine relative to an active control (Murrough et al., 2013).
- A meta analysis of individual patient data reported a rapid reduction in suicidal ideation in the days after a single infusion (Wilkinson et al., 2018).
- Esketamine, the nasal spray version, earned FDA approval for treatment resistant depression after its own clinical trial program (FDA, Spravato).
The research is promising, and it is not a promise of results. Response rates vary, and some people do not benefit. We will be honest with you about what the data does and does not support.
What Treatment Looks Like
A typical course begins with a series of infusions across two to three weeks, which allows us to gauge your response. From there we design a maintenance plan with sessions spaced to your needs. A clinician monitors your vital signs during every infusion. Our what to expect page describes each visit in detail.
Realistic Outcomes
In published trials, many participants with treatment resistant depression experienced a clinically significant reduction in symptoms, frequently on a faster timeline than oral antidepressants allow. Others responded only partially, and some did not respond. We never promise a permanent fix or a certain outcome. We aim for meaningful, honestly measured relief.
Safety and Screening
Because ketamine is not right for everyone, our physician reviews your full medical and psychiatric history and screens for conditions that raise risk. Monitoring during infusions and a supervised recovery period are standard. This careful screening is built into the consultation that every patient completes first.

Common Questions About Treatment Resistant Depression
What counts as treatment resistant depression?
Treatment resistant depression generally means depression that has not responded adequately to at least two different antidepressants taken at the right dose for the right length of time. Our physician confirms whether this describes your situation during the consultation.
Why would ketamine work when other medications did not?
Standard antidepressants act mainly on serotonin and related systems. Ketamine acts on the glutamate system and is thought to support new connections between brain cells, a different pathway. That difference is part of why it can help some people who did not respond to other drugs.
How long do the benefits last?
Benefits from an initial series often last weeks, and many patients use spaced maintenance sessions to extend relief. Durability varies. We build a realistic maintenance plan with you rather than promising a fixed result.
Is esketamine (Spravato) the same thing?
Spravato is esketamine, a nasal spray that is FDA approved specifically for treatment resistant depression. Intravenous ketamine is used off label. Both are reasonable options to discuss, and we explain the trade offs during your consultation.
