Ketamine Therapy Near Deer Park, TX
There’s a point in the treatment-resistant journey where the conversation shifts. It stops being about which medication to try next and becomes about whether a fundamentally different approach exists. If you’ve reached that point — if the SSRIs, the SNRIs, the mood stabilizers, the augmentation strategies, and the therapy modalities have all had their turn without delivering the change you need — then this page was written for you.
The reason conventional treatments plateau isn’t complicated. They all operate within the same narrow lane of brain chemistry: serotonin, norepinephrine, dopamine. Adjusting doses, combining drugs, switching classes — those are variations on a single theme. For roughly a third of patients, that theme doesn’t contain the answer. Ketamine therapy opens an entirely different chapter. It acts on the glutamate system — the brain’s most active and widespread signaling network — and triggers rapid restoration of the neural connections that chronic depression, anxiety, PTSD, and pain have steadily degraded. A recent multi-site study highlighted by Michigan Medicine found that after just three infusions over 11 days, 52% of participants with severe treatment-resistant depression achieved remission, with half of those experiencing frequent suicidal thoughts reporting a dramatic reduction in those impulses. Catalyst Health & Wellness delivers this treatment through three Houston-area clinics, all led by Dr. Ho — a physician whose board certifications in both anesthesiology and pediatrics equip him with the pharmacological expertise and patient-centered demeanor that safe, effective ketamine administration requires.

How Ketamine Works — and Why It Succeeds Where Other Treatments Stall
Ketamine’s history stretches back six decades. Synthesized in 1962, it received FDA approval as a general anesthetic in 1970 and quickly became a staple of surgical suites, emergency rooms, and military field hospitals worldwide. That track record translates into one of the most extensively studied safety profiles in modern pharmacology.
Its psychiatric chapter opened unexpectedly in the late 1990s. Scientists investigating glutamate’s role in brain function noticed that patients given low-dose ketamine experienced rapid, substantial improvements in depression — improvements that arrived in hours rather than weeks, and that occurred even in patients who hadn’t responded to any prior antidepressant. The mechanism behind this effect is now well understood. Standard antidepressants boost the activity of chemical messengers the brain already produces and then hope the brain adapts favorably over time. Ketamine doesn’t wait for adaptation. It blocks NMDA receptors within the glutamate system, initiating a biochemical cascade that releases brain-derived neurotrophic factor (BDNF) — the protein that physically rebuilds synaptic connections in brain regions responsible for mood regulation, threat assessment, and pain processing. Chronic mental health conditions and persistent pain don’t just change how you feel — they change the structure of your brain, thinning the connections that healthy cognition depends on. Ketamine reverses that structural damage directly. And because disrupted connectivity underlies depression, anxiety, PTSD, OCD, chronic pain, and suicidal thinking alike, a single mechanism can produce improvement across multiple diagnoses simultaneously.

How We Administer Ketamine
Two established delivery methods. Both produce strong clinical results. Your treatment team will match the route to your medical profile, comfort level, and therapeutic goals.

IV Ketamine Therapy
Intravenous delivery introduces ketamine directly into the bloodstream through a small catheter, providing your clinician with continuous, real-time dosing control. Need a modest adjustment up to optimize the therapeutic window? It happens instantly. Need to ease back to manage a transient side effect? Equally immediate. That responsiveness is why IV administration remains the reference standard in ketamine therapy. Mood disorder sessions typically run 40 to 60 minutes.

IM Ketamine Therapy
Intramuscular delivery uses a single injection — typically in the deltoid or thigh — and skips the IV entirely. The medication enters the bloodstream through muscle tissue and produces the same fundamental therapeutic response. Patients who prefer a simpler setup, feel anxious about IVs, or have veins that don't cooperate easily often find IM delivery more comfortable. Full monitoring in a private treatment room continues throughout. We'll discuss both options during your consultation. The right choice is the one that matches your clinical needs and personal comfort — and we'll help you arrive at that choice without pushing in either direction.

Your Treatment Journey at Catalyst
Clear expectations from start to finish. Here's every step of ketamine therapy, so you know exactly what's coming and can focus on what matters — getting better.
Step 1: Free Phone Consultation
Call (713) 772-5315 and tell us what’s been going on. No referral needed. No insurance pre-authorization. Just a straightforward conversation about your symptoms, your treatment history, and whether ketamine therapy makes sense for your situation.
We’ll walk through:
- Your day-to-day experience — what symptoms look like when they’re at their worst
- The full inventory of treatments you’ve already tried and how each one played out
- A clear explanation of how ketamine therapy works, what it costs, and what the timeline involves
- Realistic outcome expectations based on your specific condition and history
- Any questions or concerns you want addressed before making a decision
No charge. No commitment. Just information delivered with honesty and without sales pressure.
Step 2: Medical Intake
After your consultation, we’ll send a comprehensive intake form. Take your time with it — every detail you share feeds directly into the protocol we design for you. We’ll ask about medication responses (both helpful and harmful), physical health factors, symptom timing and triggers, sleep patterns, and what meaningful improvement would look like in the context of your actual life. If coordinating with your existing providers — psychiatrist, therapist, primary care doctor — would strengthen your care, we’ll reach out with your permission. It’s optional, but it almost always adds value.
Step 3: Your First Visit
Preparation couldn’t be simpler:
- Nothing to eat for at least 6 hours before treatment
- Clear liquids in small amounts are fine up to 2 hours beforehand
- Comfortable clothing — the more relaxed you feel physically, the better
Once you arrive:
- We’ll address any remaining questions and walk through the session step by step
- Record your baseline vital signs
- Place the IV line or prepare the injection site
Dr. Ho’s pediatric training shows up right here. He spent years inserting IVs in children who needed gentleness above everything — a skill that translates directly to adult patients who feel anxious about needles. He selects the smallest gauge needle the treatment allows, offers topical numbing cream before any skin contact, and keeps a portable ultrasound available for patients whose veins are challenging. Most patients say the IV placement was the part they dreaded most and barely noticed.
Step 4: The Session Itself
You’ll recline in a padded chair inside a private treatment room built for comfort, not clinical sterility:
- Noise-cancelling headphones with calming playlists
- A soft eye mask
- A warm blanket
- Lighting you control
Session length varies by condition:
- Mood disorders (depression, anxiety, PTSD, OCD): roughly 40 minutes of active treatment plus 20 minutes of recovery
- Chronic pain conditions (fibromyalgia, migraines, EDS, CRPS, complex pain): approximately 4 hours of treatment plus 2 hours of recovery
The longer chronic pain protocol allows ketamine’s NMDA-blocking effects the time required to fully engage central sensitization — the nervous system amplification that keeps chronic pain alive long after the original tissue damage has resolved.
Vitals are monitored continuously throughout. Dr. Ho or a clinical team member stays present and checks in at regular intervals. If you’re nervous about your first session, that’s completely expected — and nearly everyone says afterward that the experience was quieter, safer, and more calming than they’d anticipated.
Step 5: Post-Treatment Recovery
When the infusion or injection ends, you’ll rest comfortably while the effects gradually subside. Most patients feel clear-headed and stable within 20 to 60 minutes.
Important logistics:
- You cannot drive yourself home — please arrange a ride before arriving
- Plan a low-key remainder of the day, preferably with someone you trust nearby
- Hold off on major decisions, heavy exertion, or operating machinery until the following day
- We’ll follow up by phone that evening or the next morning to check in
At the carefully calibrated sub-anesthetic doses we use, serious adverse events are rare. But our team stays reachable by phone if anything concerns you after you leave.
Step 6: Your Ongoing Treatment Plan
How quickly ketamine works varies person to person. Some patients feel a dramatic change after their first session. For others, improvement accumulates steadily across the initial series. Both trajectories are normal and expected.
Here’s the general framework:
- Initial series: 6 sessions spread over 2 to 3 weeks for mood conditions
- Dosing adjustments between each session, informed by your specific response
- A maintenance schedule designed around your results — weekly, biweekly, or monthly
- Reassessment at every appointment to keep your protocol aligned with your evolving needs
Nothing about this plan is rigid. It responds to you — your data, your feedback, your goals — and shifts whenever the evidence says it should.
The Science Backing Ketamine Therapy
Ketamine didn’t become a psychiatric treatment through anecdote or early enthusiasm. Its credibility rests on decades of controlled, peer-reviewed research from some of the most respected institutions in medicine.
The landmark trial came from the National Institutes of Health: a single IV ketamine infusion produced a 71% response rate among patients with treatment-resistant depression — versus 0% in the placebo group. No controlled psychiatric drug study has ever matched that separation (Zarate et al., 2006).
That finding was validated under tighter experimental conditions in a multi-center trial that used an active placebo to control for the effects of sedation. The outcome: a 64% response rate within 24 hours compared to 28% with the active control, yielding a number needed to treat of just 2.8 (Murrough et al., 2013).
On the mechanistic front, a publication in Science revealed that ketamine directly repairs the synaptic damage chronic stress inflicts, driving measurable new neural connection growth in the prefrontal cortex within a single day (Li et al., 2010).
For PTSD, a controlled trial at the Icahn School of Medicine demonstrated that repeated ketamine infusions produced sustained, clinically significant symptom improvement, with approximately two-thirds of participants reaching response thresholds (Feder et al., 2014).
The City of Deer Park is a hardworking community that values straightforward solutions and measurable results. Ketamine therapy delivers both — grounded in the kind of rigorous evidence that earns trust.
What the research consistently establishes:
- Ketamine acts through the glutamate pathway — entirely separate from the serotonin, norepinephrine, and dopamine systems targeted by every conventional antidepressant
- Response rates of 60-71% in treatment-resistant depression dramatically outperform the 10-15% success rate of switching between standard medications
- Synaptic regrowth begins within hours, confirmed by neuroimaging — the fastest structural brain repair ever documented for a psychiatric treatment
- The same neural restoration process simultaneously benefits depression, anxiety, PTSD, OCD, chronic pain, and suicidal ideation

Commonly Asked Questions
Get Help NowWhen will I start feeling the effects of ketamine?
Many patients notice improvements within hours of their first treatment, though some people need a few sessions before experiencing the full benefit. This rapid action is one of ketamine’s most remarkable qualities, especially compared to traditional antidepressants that can take 4 to 8 weeks to work.
How safe is ketamine therapy?
Yes, when administered by trained medical professionals in a controlled setting. Ketamine has been used safely as an FDA-approved anesthetic for over 50 years. Dr. Ho’s expertise as an anesthesiologist ensures the highest safety standards. We monitor your vital signs throughout treatment, and serious complications are rare.
What does the full treatment course look like?
Most patients receive an initial series of six treatments over two to three weeks. After that, you’ll likely need maintenance treatments to sustain your improvements. The frequency varies based on individual response. Some people return every few weeks, while others maintain their benefits with monthly treatments. We’ll work with you to find the schedule that keeps you feeling your best.
What happens during a ketamine session?
Experiences vary from person to person. Many patients describe feeling relaxed, peaceful, or slightly disconnected from their surroundings. Some people have visual or sensory experiences, while others simply feel calm. These effects are temporary and subside as the ketamine wears off. Most patients find the experience pleasant and therapeutic.
Will I be able to drive after my session?
No, you cannot drive yourself home after ketamine treatment. You’ll need to arrange transportation. By the time you leave our facility, you’ll feel much clearer, but for your safety, you should not drive, operate heavy machinery, or make important decisions for the rest of the day.
How long will the improvement last after treatment?
This varies considerably between individuals. Some people maintain their improvement for weeks or even months after their initial series. Others need more frequent maintenance treatments. During your follow-up appointments, we’ll assess how you’re responding and adjust your maintenance schedule accordingly.
Can ketamine be combined with my existing medications?
In most cases, yes. Ketamine typically works well alongside other psychiatric medications. However, we’ll review your complete medication list during your consultation to ensure there are no contraindications. Never stop taking prescribed medications without consulting your prescribing physician.
Do I need my doctor to refer me?
No, you don’t need a referral to begin ketamine therapy at Catalyst Health & Wellness. However, communication with your current healthcare providers can be helpful, and we encourage coordination of care whenever possible.
