Ketamine Therapy for Depression and Anxiety in Florida | New Option

Reviewed by Hilary Ortega, NP — Florida-licensed

Medically reviewed by our Florida clinical team. Last updated October 2026.

Low-dose ketamine works in hours, not weeks — and it offers new hope for patients whose depression or anxiety has not responded to SSRIs. ([2022 review on ketamine treatment for depression](https://pmc.ncbi.nlm.nih.gov/articles/PMC9010394/))

The psychiatric playbook hasn't changed much in decades: we give you a pill, tell you to wait six weeks, and hope for the best. Statistics show those meds only work for about half the folks who try them, which is a frustrating reality I've seen play out in clinic too many times. Low-dose ketamine therapy has flipped that script entirely. Because it hits a completely different set of receptors, it often brings relief in hours, providing a real path forward for patients who honestly thought they’d run out of options. [1]

What exactly is low-dose ketamine?

For over fifty years, ketamine has been a staple in operating rooms, but lately, we’ve found its real magic happens at a tiny fraction of that surgical dose. This lower amount induces a quiet, dissociative state where the brain basically hits a reset button and starts self-repairing. While you'll see it given through IVs or shots in some clinics, our protocol focuses on supervised at-home sessions using sublingual lozenges to keep things comfortable and accessible. [2]

The science behind the shift

Look—standard SSRIs focus on serotonin, but ketamine targets glutamate, which is your brain's big-picture excitatory neurotransmitter. By blocking NMDA receptors for a short window, the drug triggers a release of BDNF—think of it like 'Miracle-Gro' for your neurons—to regrow the synaptic connections that chronic stress and depression have essentially pruned away. Believe it or not, imaging studies show these physical structural changes happening in the brain as soon as 24 hours after one dose. [3]

Is this right for you?

  • Adults struggling with treatment-resistant depression who haven't seen results from at least two different SSRIs.
  • Folks dealing with severe anxiety that just isn't budging with standard first-line therapies.
  • Anyone experiencing suicidal ideation who needs relief much faster than traditional antidepressants can provide.
  • Candidates who have passed our thorough screening for psychiatric and cardiovascular health.

Inside a typical session

Patients often tell me they feel a 'gentle distance' from their own thoughts during a session. It’s a mild dissociation—you might feel like you're floating or observing your life from a few steps back—which finally allows you to process painful stuff without feeling totally overwhelmed by it. The experience usually peaks around the 45-minute mark and wears off within two hours. You're awake the whole time, resting in your own bed with a support person right there to keep things grounded. [1]

The structure of your treatment

We start with an induction phase, which is typically 6 to 8 sessions spread over a few weeks, then we taper into maintenance sessions based on how you're feeling. I always tell my patients that the lozenge is only half the work; the lasting change comes from our clinician-led preparation and integration calls. It's about how you process what came up during the session that makes the relief stick.

Safety, screening, and limits

I’ll be straight with you: ketamine isn't a silver bullet for everyone. We have to rule out people with active psychosis, uncontrolled high blood pressure, or untreated thyroid issues to keep things safe. Every intake involves a deep dive into your psych history and a solid in-home safety plan. Also, if you’re in a true emergency right now, please put the computer down and call 911 immediately.

My final take

Don't look at low-dose ketamine as a total replacement for therapy or healthy habits; it’s an accelerator for when those tools haven't been enough. For the right person, it provides more headspace and relief in a single fortnight than years of conventional medication ever did. It’s about giving your brain the breathing room it needs to actually start healing.

Key Clinical Studies

A short, responsible summary of recent peer-reviewed research relevant to this topic. This is for education only, not medical advice.

Efficacy of ketamine therapy in the treatment of depression

Indian Journal of Psychiatry · 2019

Key finding: Subanesthetic ketamine (0.5 mg/kg IV) produced robust, rapid antidepressant effects that were visible immediately and largely sustained at one month in patients with depression.

Why it matters: Supports the rapid onset and structured dosing protocol used in our at-home low-dose ketamine program.

Extended-release ketamine tablets for treatment-resistant depression

Nature Medicine · 2024

Key finding: 180 mg twice-weekly extended-release ketamine tablets significantly improved MADRS scores vs placebo in treatment-resistant depression, with good tolerability and mostly at-home dosing.

Why it matters: Demonstrates that controlled at-home ketamine delivery can be both safe and effective for difficult-to-treat cases.

View study

Ketamine vs ECT for non-psychotic treatment-resistant major depression

New England Journal of Medicine · 2023

Key finding: Intravenous ketamine was non-inferior to electroconvulsive therapy for non-psychotic treatment-resistant depression, with roughly 55% of ketamine patients showing sustained improvement.

Why it matters: Reinforces ketamine as a credible option for patients who have not responded to traditional antidepressants.
