Ketamine Therapy in Katy, TX
Here’s something that should be talked about more openly: the medications most commonly prescribed for depression, anxiety, and PTSD all work through the same basic mechanism. They adjust serotonin, norepinephrine, or dopamine levels. That’s it. When your doctor switched you from one antidepressant to another, the new drug was essentially running the same play through a slightly different formation. For millions of people, one of those formations connects. For roughly a third, none of them do — and the reason has nothing to do with willpower, compliance, or how badly you want to get better.
It has to do with brain architecture. When chronic mental illness persists despite adequate treatment, the issue often sits deeper than neurotransmitter levels. It lives in the physical connections between neurons — the synapses that allow brain regions responsible for mood, cognition, and emotional regulation to communicate. Chronic depression, anxiety, trauma, and pain gradually degrade those connections. Standard antidepressants can’t rebuild them. They were never designed to. Ketamine was designed for something else entirely — anesthesia — but its ability to trigger rapid synaptic regrowth turned out to be the most significant psychiatric discovery in decades. The National Alliance on Mental Illness (NAMI) recognizes ketamine and its derivative esketamine as treatments for depression that hasn’t responded to other medications, noting their distinctly different mechanism of action from traditional antidepressants. Catalyst Health & Wellness delivers this treatment across three Houston-area clinics, each under the direct supervision of Dr. Ho — a board-certified anesthesiologist and former pediatrician whose training uniquely equips him for the precision dosing, real-time monitoring, and compassionate patient care that ketamine therapy demands.

What Ketamine Is — and What Makes It Fundamentally Different
Ketamine’s story began in an operating room, not a psychiatrist’s office. Synthesized in 1962, it earned FDA approval as a general anesthetic in 1970 and quickly became one of the most widely used surgical medications in the world — trusted in hospitals, emergency departments, pediatric units, and combat field stations across six decades and millions of patients. That unmatched track record is the foundation of its safety profile.
The turn toward psychiatry came by accident. In the late 1990s, neuroscientists studying the glutamate signaling system — the brain’s primary and most active communication network — observed something no existing antidepressant had ever produced: patients given sub-anesthetic ketamine experienced rapid, robust improvements in depression. Not in weeks. In hours. And not only in patients with mild cases — in the treatment-resistant patients who had exhausted every other option.
The science has since explained why. Standard antidepressants increase the availability of serotonin, norepinephrine, or dopamine in the synaptic gap, then wait for the brain to adapt. That adaptation takes four to eight weeks when it happens at all. Ketamine skips the waiting game. It blocks NMDA receptors in the glutamate system, triggering a rapid biochemical cascade that releases brain-derived neurotrophic factor (BDNF). BDNF is the brain’s construction protein — it physically builds new synaptic connections in regions governing mood regulation, threat assessment, and pain processing. Chronic conditions don’t just alter your chemistry. They alter your brain’s wiring. Ketamine repairs that wiring directly, which is why it produces improvements across conditions that appear clinically distinct — depression, anxiety, PTSD, OCD, chronic pain, suicidal thinking — but share a common structural deficit.

Ketamine Delivery Methods
Two established routes. Same therapeutic target. We select the method that suits your body, your comfort level, and your clinical goals.

IV Ketamine Therapy
Intravenous delivery sends ketamine directly into the bloodstream through a small catheter, giving your clinician moment-to-moment control over the infusion rate. This means real-time dose optimization — adjustments happen instantly based on your body's response. That precision is why IV administration remains the gold standard in ketamine therapy research and clinical practice. Mood disorder sessions typically last 40 to 60 minutes.

IM Ketamine Therapy
Intramuscular delivery uses a single injection — usually in the upper arm or thigh — and eliminates the need for IV access altogether. The medication absorbs through muscle tissue and produces the same core therapeutic effects. Patients who find IVs stressful, whose veins are difficult to access, or who simply prefer a less involved setup often find IM delivery a better fit. Full monitoring continues throughout in a private treatment room. We'll discuss both options during your consultation and help you choose based on your medical profile and personal comfort — without steering you toward either one.

What to Expect: Your Treatment Journey
Full transparency from the first phone call to your ongoing maintenance plan. No ambiguity, no surprises — just a clear path forward.
Step 1: Free Phone Consultation
Pick up the phone and call (713) 772-5315. That’s the only step between where you are right now and a real conversation about whether ketamine therapy fits your situation. No referral. No insurance pre-authorization. No gatekeepers.
Here’s what we’ll walk through together:
- Your daily reality — how symptoms show up, when they’re worst, and what they prevent you from doing
- A complete picture of every treatment you’ve tried and how each one played out
- A straightforward explanation of how ketamine therapy works and whether your clinical profile aligns with it
- Honest numbers on cost, timing, and what realistic progress looks like
- Space for every question or concern you’re carrying
Free. No pressure. No sales pitch. Just information that helps you make a clear decision.
Step 2: Medical Intake
Once you decide to move forward, we’ll send a detailed intake form. The time you invest here pays off directly — every piece of information you share shapes the protocol we design for you. We’ll ask about medication responses (good and bad), your physical health landscape, symptom patterns throughout the day, sleep quality, and what meaningful improvement actually looks like within your specific life. Want us to coordinate with your psychiatrist, therapist, or primary care physician? We’re happy to — with your permission. It strengthens care but isn’t required.
Step 3: Your First Visit
Preparation is minimal:
- Nothing to eat for at least 6 hours before treatment
- Clear liquids in small sips are fine up to 2 hours beforehand
- Comfortable, relaxed clothing
When you arrive:
- We’ll answer remaining questions and walk through every moment of the session
- Record baseline vital signs
- Place the IV or prepare the injection site
Dr. Ho spent years inserting IVs in pediatric patients — kids who needed skill matched with tenderness. That experience carries into every adult session. He selects the smallest gauge needle appropriate for the treatment, offers topical numbing cream before any skin contact, and keeps a portable ultrasound available for veins that are difficult to locate. Nearly every patient says needle placement was the thing they feared most and noticed least.
Step 4: The Session Itself
You’ll settle into a comfortable recliner inside your own private treatment room:
- Noise-cancelling headphones loaded with calming playlists
- A soft eye mask
- A warm blanket
- Dimmable, adjustable lighting
Session duration varies by condition:
- Mood disorders (depression, anxiety, PTSD, OCD): approximately 40 minutes of active treatment plus 20 minutes of recovery
- Chronic pain conditions (fibromyalgia, migraines, EDS, neuropathy, complex pain): approximately 4 hours of treatment plus 2 hours of recovery
The extended pain protocol gives ketamine the sustained engagement time necessary to meaningfully address central sensitization — the neural amplification that keeps chronic pain firing long after the original source has resolved.
Continuous vital sign monitoring throughout. Dr. Ho or a clinical team member stays present, checking in at regular intervals. First-session anxiety is completely normal — and almost universally resolved once patients experience how calm, quiet, and controlled the process actually is.
Step 5: Post-Treatment Recovery
When treatment concludes, you’ll rest comfortably as the effects gently fade. Most patients feel clear-headed and steady within 20 to 60 minutes.
Important details:
- You can’t drive home — have your ride arranged before you arrive
- Keep the remainder of the day relaxed, ideally with someone you trust nearby
- No major decisions, intense physical activity, or machinery until the following day
- Our team will follow up by phone that evening or the next morning
At the sub-anesthetic doses we administer, serious adverse events are rare. But you’re never more than a phone call away from our clinical team if something feels off.
Step 6: Your Ongoing Treatment Plan
How quickly you respond to ketamine varies. Some patients notice a significant shift after the first session. For others, improvement builds steadily across multiple treatments. Both timelines are completely normal.
The general structure:
- Initial series: 6 sessions over 2 to 3 weeks for mood conditions
- Dose calibration between each session based on your individual response data
- Maintenance schedule tailored to your trajectory — weekly, biweekly, or monthly
- Reassessment at every appointment to keep the protocol aligned with where you actually are
Nothing is set in stone. Your protocol responds to your data, your feedback, and your evolving goals — adjusting as the evidence demands.
The Research Behind Ketamine Therapy
Ketamine’s credibility in psychiatry wasn’t built on anecdote. It rests on decades of rigorous, peer-reviewed research from leading medical institutions around the world.
The breakthrough 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 — the largest separation ever recorded in a controlled psychiatric medication trial (Zarate et al., 2006).
A multi-center replication using an active placebo — designed to eliminate the confound of sedation effects — confirmed a 64% response rate within 24 hours compared to 28% in the control group, yielding a number needed to treat of just 2.8 (Murrough et al., 2013).
On the biological side, a publication in Science revealed the mechanism: ketamine directly repairs the synaptic damage caused by chronic stress, driving new neural connection growth in the prefrontal cortex within 24 hours (Li et al., 2010).
For PTSD specifically, a controlled trial at the Icahn School of Medicine at Mount Sinai showed that repeated ketamine infusions produced sustained, clinically meaningful symptom improvement, with approximately two-thirds of participants reaching response criteria (Feder et al., 2014).
The City of Katy — a community that’s grown from a quiet railroad town into one of Houston’s most dynamic suburban corridors — has always valued pragmatic solutions backed by substance. These research findings deliver exactly that.
What the body of evidence consistently shows:
- Ketamine engages the glutamate system — a pathway entirely separate from the serotonin, norepinephrine, and dopamine systems targeted by all conventional antidepressants
- Response rates of 60-71% in treatment-resistant depression dramatically outperform the 10-15% success rate of simply 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 underlying mechanism simultaneously benefits depression, anxiety, PTSD, OCD, chronic pain, and suicidal ideation

Your brain didn’t reject those medications because it’s broken. It rejected them because they weren’t speaking its language. The serotonin system, the norepinephrine system, the dopamine system — those are three channels. Ketamine opens the fourth: the glutamate pathway, where the structural damage behind treatment-resistant conditions actually lives. It doesn’t nudge your chemistry and hope for the best. It rebuilds the connections that chronic illness dismantled.

Commonly Asked Questions
Get Help NowHow soon can I expect to notice changes after ketamine treatment?
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.
What are the safety considerations for 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 a typical treatment series look like from start to finish?
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 should I expect to feel 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.
Do I need someone to drive me home afterward?
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 should I expect the therapeutic effects to continue?
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.
Is ketamine safe to take alongside my other 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 to get a referral before scheduling?
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.
