Depression — what we treat
- Persistent low mood lasting weeks to months
- Loss of interest in previously enjoyed activities (anhedonia)
- Sleep disturbance (insomnia or hypersomnia)
- Energy loss, fatigue out of proportion to activity
- Difficulty concentrating or making decisions
- Feelings of worthlessness or excessive guilt
- Recurrent thoughts of death or self-harm
How ketamine works for depression
Standard antidepressants work through monoamine systems (serotonin, norepinephrine, dopamine) and take weeks to months to produce mood improvement. Ketamine works on the glutamate system via NMDA receptor modulation, triggering a downstream cascade that increases synaptic plasticity and BDNF expression. The clinically observable effect is rapid — many patients describe meaningful mood improvement within hours to days, compared to the 4-8 week lag with SSRIs. The FDA designated ketamine's nasal-spray cousin (esketamine, Spravato) as a Breakthrough Therapy for treatment-resistant depression in 2019.
The at-home protocol
At-home ketamine therapy for depression typically begins with an induction phase of 6-8 sessions over 4-6 weeks, then transitions to a maintenance schedule based on response. Sublingual rapid-dissolve tablets are used at home with a peer supervisor present. Doses are calibrated to the patient, starting low and adjusting based on tolerability and therapeutic response. PHQ-9 scores are tracked across the course as an objective response marker.
Who's a candidate
Patients with major depressive disorder, persistent depressive disorder, or treatment-resistant depression (defined as inadequate response to ≥2 antidepressant trials at adequate dose and duration) are candidates. Patients with bipolar depression require a stable mood-stabilizer regimen first. Patients with active psychosis, uncontrolled blood pressure, untreated substance use disorder, or pregnancy are not candidates. The eligibility intake screens all of this in detail before any prescription is issued.
Depression in California: the local picture
California has roughly 39 million residents, and national survey data (SAMHSA NSDUH 2022) suggests around 8% of adults experience a major depressive episode in a given year — on the order of 2.4 million Californians annually with active depression, the largest absolute caseload of any state. Access is starkly uneven: the coastal metros hold a deep psychiatric workforce while the Central Valley, Inland Empire, and the rural north carry HRSA-designated mental-health professional shortage areas, and even insured patients in Los Angeles and the Bay Area routinely face weeks-to-months waits for a psychiatric intake. Telehealth-delivered at-home ketamine therapy was designed to clear exactly that bottleneck, and California's telehealth statute (Business & Professions Code 2290.5) is among the clearest in the country in treating video care as the ordinary practice of medicine.
Ketamine therapy for Fountain Valley (Orange County) residents
Fountain Valley calls itself "a nice place to live," and its healthcare corridor along Warner is genuinely strong — for physical medicine. Specialty mental health is thinner. At-home ketamine therapy adds a physician-led option for treatment-resistant depression and anxiety that requires no clinic at all.
Treatment is delivered entirely via telehealth. Fountain Valley-area patients complete an online eligibility intake, have a video consult with Dr. Soffer, and receive prescription medication via mail. Sessions take place in the patient's home with a peer supervisor present. No travel to a clinic, no in-person visits required, anywhere in Orange County.
Depression + ketamine — common questions
Is at-home ketamine therapy for depression legal in California?
Yes. Ketamine is a Schedule III controlled substance that a California-licensed physician can prescribe off-label via telemedicine under Business & Professions Code 2290.5, consistent with the federal Ryan Haight Act's telemedicine rules (a live video visit with the prescribing physician establishes the relationship). California adds a safeguard most states lack: the physician consults CURES, the state prescription-monitoring database, before prescribing. The compounded sublingual ketamine is dispensed by a licensed California pharmacy and shipped to your home.
How fast does ketamine therapy work for depression?
Many patients describe meaningful mood improvement within hours to days of the first session, with continued gains over the 6-8 session induction phase. This is fundamentally different from SSRIs, which typically require 4-8 weeks before any benefit appears. The rapid onset is one of the main reasons ketamine is studied for depression that hasn't responded to traditional medications.
Will I have to stop my antidepressant to do ketamine therapy?
No, in most cases. SSRIs, SNRIs, and most other antidepressants are considered compatible with at-home ketamine therapy and continue throughout treatment. Benzodiazepines and certain other medications may require timing adjustments around sessions. Every intake includes a complete medication review before prescribing.
How long does the antidepressant effect of ketamine last?
After the induction series, individual responses vary widely. Some patients maintain benefit with monthly or every-other-month maintenance sessions; others sustain remission for longer periods between sessions. The maintenance schedule is calibrated to each patient based on their response curve and PHQ-9 trajectory.
