IV ketamine doesn't mask symptoms. It targets the biological infrastructure that depression, trauma, and chronic pain have degraded — and helps your brain repair it.
For decades, psychiatry operated on the serotonin hypothesis — the idea that depression is caused by low serotonin levels. SSRIs and SNRIs were built on this model. They increase the amount of serotonin or norepinephrine floating between neurons.
The problem: the serotonin hypothesis has never been proven. A landmark 2022 meta-analysis published in Molecular Psychiatry (Moncrieff et al.) concluded there is no convincing evidence that depression is caused by serotonin abnormalities. This doesn't mean SSRIs don't help some people — they do. But it explains why they fail for roughly 30–40% of patients and take 4–8 weeks to show any effect at all.
If you've tried two or more antidepressants without adequate relief, clinicians classify your condition as treatment-resistant depression (TRD). You're not broken. The medications were targeting the wrong pathway.
Glutamate is the brain's primary excitatory neurotransmitter. It's involved in roughly 90% of all synaptic connections. Where serotonin is a supporting player, glutamate is the infrastructure itself — the electrical grid of the brain.
Here's what happens when ketamine enters your system:
Ketamine is an NMDA receptor antagonist. It temporarily blocks specific glutamate receptors on inhibitory interneurons. This releases a cascade — a burst of glutamate activity in areas of the brain that depression has quieted.
The released glutamate activates AMPA receptors, triggering a signaling pathway called mTOR (mechanistic target of rapamycin). This is the master switch for protein synthesis in neurons. When mTOR activates, your brain starts building.
BDNF is essentially fertilizer for your brain. It promotes the growth, survival, and differentiation of neurons. Depression, chronic stress, and PTSD all reduce BDNF levels. Ketamine rapidly increases them — sometimes within hours.
This is neuroplasticity in action. The mTOR pathway + elevated BDNF trigger the formation of new dendritic spines — the physical connection points between neurons. Studies using two-photon microscopy have shown visible new spine growth within 24 hours of a single ketamine dose. Your brain is literally rebuilding its wiring.
Depression disrupts connectivity in the prefrontal cortex and default mode network. As new synapses form and strengthen, these networks restore. Patients describe it as the fog lifting, as color returning to the world, as feeling like themselves again for the first time in years.
Not all ketamine delivery methods are equal. The route of administration determines how much of the drug actually reaches your brain — this is called bioavailability.
When you swallow a ketamine tablet or dissolve a lozenge under your tongue, the drug passes through your digestive system and liver before reaching your brain. This first-pass metabolism destroys 70–85% of the active compound. You're getting a fraction of the dose.
IV ketamine bypasses all of this. It enters your bloodstream directly, meaning your anesthesia provider can control the exact dose reaching your brain in real time. They can adjust the rate based on how you're responding. This precision is why IV ketamine produces more reliable, more predictable results — and why it requires trained anesthesia professionals to administer safely.
There's a lot of mystery around what a ketamine session feels like. Here's the truth: it varies. But there are common threads.
You'll arrive, settle into a private treatment suite, and meet with your provider. We'll review your protocol, check vitals, and set up hospital-grade monitoring. Weighted blanket, eye mask, and a curated music playlist are ready. Walter White or Wilma are available if you'd like company.
The infusion typically lasts 40–60 minutes. Most patients describe a deep state of relaxation — a sense of distance from their usual thought patterns. Some experience visual shifts, a floating sensation, or a feeling of emotional openness. Your anesthesia provider monitors every vital sign throughout and adjusts the infusion in real time.
You'll spend 15–30 minutes in our recovery lounge as the effects fully subside. Most patients feel a sense of calm, sometimes lightness. Some notice a shift in mood within hours. Others feel it develop over the first few sessions. You'll need someone to drive you home — no exceptions.
The doses used in therapeutic ketamine are calibrated for neuroplasticity, not dissociation. Your provider controls the rate, monitors your response, and adjusts in real time. This is a medical procedure administered by anesthesia professionals with hospital-grade equipment. The clinical environment is what separates therapeutic outcomes from everything else.
When two or more antidepressants have failed. IV ketamine offers a fundamentally different mechanism targeting the glutamate system. 45–65% response rate in this specific population.
Generalized anxiety, social anxiety, and panic disorder. Ketamine's rapid BDNF release and prefrontal cortex restoration can interrupt the anxiety feedback loop that talk therapy and SSRIs haven't reached.
Trauma rewires neural pathways into hypervigilance and fear responses. Ketamine promotes neuroplasticity in the amygdala and prefrontal cortex — the exact regions PTSD has hijacked — creating a window for the brain to form new, healthier patterns.
Ketamine blocks NMDA receptors involved in central sensitization — the process where your nervous system amplifies pain signals. IV ketamine can reset this amplification, particularly in neuropathic pain, CRPS, fibromyalgia, and migraine disorders.
Obsessive-compulsive disorder involves dysregulated glutamate signaling in the cortico-striatal-thalamic circuit. Ketamine's direct action on this system can provide rapid symptom reduction where SSRIs and CBT have plateaued.
This is where speed matters most. A 2018 study in the American Journal of Psychiatry showed ketamine reduced suicidal thoughts within hours. The rapid onset makes it a critical intervention when other treatments are too slow.
When administered by trained anesthesia professionals with hospital-grade monitoring, IV ketamine has an excellent safety profile. It has been used in anesthesia since 1970 and is on the WHO's List of Essential Medicines. Our team monitors heart rate, blood pressure, oxygen saturation, and respiratory function throughout every session.
There's no universal template. Most patients begin with an initial series of infusions, typically over 2–3 weeks. Your provider builds your protocol based on how you respond — not a one-size-fits-all schedule. Some patients transition to monthly maintenance sessions; others need them less frequently.
Most insurance plans do not cover IV ketamine for mental health indications, as it remains an off-label use. We provide superbills that you can submit for potential out-of-network reimbursement. We're transparent about costs upfront — no surprises.
In most cases, yes. Ketamine works through a different mechanism than SSRIs, SNRIs, and most other psychiatric medications. However, certain medications (particularly MAOIs and benzodiazepines) may require adjustment. We review your complete medication list during your initial conversation.
No. Spravato is an intranasal spray containing only the S-enantiomer of ketamine. IV ketamine delivers the racemic mixture (both S and R enantiomers) directly into your bloodstream at ~100% bioavailability. The R-enantiomer has distinct anti-inflammatory and analgesic properties that Spravato lacks. Additionally, IV allows real-time dose adjustment that intranasal cannot.
No. Therapeutic ketamine doses are sub-anesthetic — well below what would be used for surgical anesthesia. You'll remain conscious throughout. Most patients describe a deeply relaxed, reflective state. Some experience mild perceptual shifts. Your provider calibrates the dose to maintain this therapeutic window.
No pressure, no intake forms to start. Just a straightforward conversation about your history, your goals, and whether ketamine therapy makes sense for your situation.
