Why Traditional Antidepressants Often Fail
For many patients with depression, anxiety, or PTSD, conventional antidepressants — SSRIs, SNRIs, and tricyclics — provide only partial relief or no relief at all. These medications act on serotonin and norepinephrine systems and typically take four to eight weeks to produce noticeable effects. Roughly one-third of patients with major depressive disorder fail to respond adequately to two or more trials of standard antidepressants, a condition known as treatment-resistant depression.
How Ketamine Works Differently
Ketamine acts on the glutamate system — specifically as an NMDA receptor antagonist — rather than on serotonin pathways. By modulating glutamate, ketamine promotes synaptogenesis: the rapid formation of new neural connections in regions of the brain associated with mood regulation, including the prefrontal cortex and hippocampus. This mechanism is fundamentally different from SSRIs and helps explain why patients often experience symptom relief within hours or days rather than weeks.
Conditions We Treat
- Treatment-resistant depression
- Severe generalized anxiety
- Post-traumatic stress disorder (PTSD)
- Acute suicidal ideation (as part of a comprehensive safety plan)
- Bipolar depression (in select cases, under close supervision)
What At-Home Ketamine Treatment Looks Like
After a thorough psychiatric evaluation and medical screening, eligible patients receive low-dose oral or sublingual ketamine to take at home under a structured protocol. Each session takes place in a calm, private setting. Patients are instructed to have a support person present, avoid driving for the rest of the day, and follow specific guidance on dosing, timing, and integration practices afterward.
Treatment is delivered as a series — typically two sessions per week for two to three weeks — followed by maintenance dosing tailored to each patient's response.
How Quickly Patients See Results
Many patients report meaningful improvement in mood, sleep, or anxiety within the first one to three sessions. For treatment-resistant depression, clinical research consistently shows rapid reductions in depressive symptoms — often within 24 hours of a dose — with cumulative benefit over a full treatment course. Response is not universal, and a careful evaluation is essential to determine whether ketamine is the right option.
Why Medical Supervision Matters
Ketamine is a powerful medication. It can interact with other psychiatric medications, raise blood pressure, and produce dissociative effects that require clinical guidance. At New Age Psychiatry, every patient is evaluated by a board-certified psychiatrist, screened for medical and psychiatric risk factors, and monitored throughout the course of treatment. We do not prescribe ketamine without ongoing clinical oversight.
Is Low-Dose Ketamine Right for You?
If you've tried multiple antidepressants without lasting relief, or if your depression, anxiety, or PTSD is interfering with daily life, an evaluation is the first step. We'll review your history, current medications, and treatment goals to determine whether ketamine therapy is appropriate — and if it isn't, we'll recommend a path that is.
