Ketamine Therapy in League City, TX
Most people assume that when one antidepressant fails, the next one offers a meaningfully different approach. It doesn’t. The second drug, the third, even the fifth — they’re all variations on the same pharmacological strategy: increase serotonin, norepinephrine, or dopamine availability in the synaptic gap and hope the brain gradually responds. For the majority of patients, one of these variations eventually connects. For the remaining third, it never does. And the reason isn’t mysterious — it’s structural.
Chronic depression, anxiety, PTSD, and persistent pain don’t just alter brain chemistry. They physically degrade the synaptic connections that allow brain regions to communicate. Standard antidepressants can adjust chemical messengers, but they can’t reconstruct the wiring those messengers travel on. That reconstruction requires an entirely different pharmacological pathway. Ketamine provides it. Acting through the glutamate system — the brain’s most pervasive and active communication network — ketamine triggers the rapid formation of new synaptic connections in the very regions that chronic illness has eroded. Healthline reports that in clinical studies, participants with treatment-resistant depression who received ketamine experienced significant improvement, with effects beginning as quickly as one hour after the first dose and lasting up to a month after completing a treatment series. Catalyst Health & Wellness brings this treatment to League City residents through three Houston-area clinics, every one directed by Dr. Ho — a board-certified anesthesiologist and former pediatrician whose combined training delivers the dosing precision, physiological monitoring, and compassionate patient care that safe ketamine therapy requires.

What Ketamine Is — and Why It Reaches What Other Treatments Can't
Ketamine didn’t emerge from psychiatry. It came from surgery. Synthesized in 1962, it received FDA approval as a general anesthetic in 1970 and became a mainstay of operating rooms, emergency departments, pediatric medicine, and military field hospitals across six decades. That continuous, high-volume clinical history provides a safety record few modern medications can approach.
Its role in mental health was discovered by accident. In the late 1990s, researchers investigating the glutamate system — the signaling pathway carrying roughly 90% of the brain’s excitatory communication — noticed that sub-anesthetic ketamine doses produced rapid, pronounced depression relief in patients who’d tried everything else. Not modest improvement over weeks. Measurable change within hours.
The mechanism has since been mapped precisely. Conventional antidepressants boost serotonin, norepinephrine, or dopamine and rely on the brain’s gradual adaptation — a process that takes four to eight weeks when it works at all. Ketamine bypasses that slow clock entirely. By blocking NMDA receptors within the glutamate system, it triggers a biochemical cascade that releases brain-derived neurotrophic factor (BDNF). BDNF is the brain’s growth protein — the molecule that physically builds new synaptic connections in regions governing mood regulation, threat perception, and pain processing. Chronic conditions thin those connections over months and years. Ketamine rebuilds them, often within a single session. This common structural deficit is why a single mechanism can produce improvement across seemingly unrelated conditions — depression, anxiety, PTSD, OCD, chronic pain, and suicidal thinking all share the same pattern of degraded neural architecture.

Ketamine Administration: Two Established Routes
Two methods. Same therapeutic objective. We match the approach to your body, your comfort, and your clinical needs.

IV Ketamine Therapy
Intravenous delivery introduces ketamine into the bloodstream through a small catheter, giving your clinician continuous, real-time control of the dose. Adjustments are immediate — optimizing the therapeutic window or managing a transient effect happens without delay. This precision makes IV the reference standard in both ketamine research and clinical practice. Mood disorder sessions typically run 40 to 60 minutes.

IM Ketamine Therapy
Intramuscular delivery uses a single injection — typically in the upper arm or thigh — bypassing the IV setup entirely. The medication enters the bloodstream through muscle tissue and produces the same core therapeutic response. Patients who feel uneasy about IV lines, whose veins are difficult, or who prefer a simpler process often choose IM. Full monitoring continues throughout in a private treatment room.
No inherent superiority between the two. We'll discuss both during your consultation and arrive at the best fit for your situation — clinical factors and personal comfort guiding the decision, not pressure.

Your Treatment Journey: Start to Finish
Full clarity at every stage. Here's what happens from your initial phone call through your ongoing maintenance plan.
Step 1: Free Phone Consultation
Call (713) 772-5315. You’ll speak with someone who understands treatment-resistant conditions from years of clinical experience — not from a call center script. No referral. No insurance pre-authorization. No gatekeeping of any kind.
We’ll discuss:
- The unfiltered reality of your daily symptoms — the version your ten-minute medication check doesn’t have time for
- Your full treatment history: medications tried, doses reached, side effects endured, therapy modalities explored
- How ketamine therapy works, why it’s different, and whether your clinical profile makes you a strong candidate
- Transparent details on cost, timeline, logistics, and realistic expectations
- Every question or concern weighing on you
Free. No obligation. No sales pitch. Just information that helps you decide with confidence.
Step 2: Medical Intake
When you decide to move forward, we send a detailed intake questionnaire. Every answer directly informs the protocol we build for you. We ask about medication responses (good and bad), your physical health, symptom timing and triggers, sleep quality, and what meaningful improvement would actually look like within your specific life. If you want us to coordinate with your existing care team — psychiatrist, therapist, primary care provider — we welcome it. Shared information strengthens every decision. But it’s always your choice.
Step 3: Your First Visit
Preparation is minimal:
- No food for at least 6 hours
- Clear liquids in small amounts okay up to 2 hours before
- Comfortable clothing
When you arrive:
- We walk through the session in full and address remaining questions
- Record baseline vital signs
- Place the IV or prepare the injection site
Dr. Ho learned needle technique in pediatric medicine — working with children who needed skill paired with extraordinary gentleness. That expertise translates directly to adult patients who feel anxious about the process. He uses the smallest practical gauge needle, offers topical numbing cream before skin contact, and keeps portable ultrasound available for challenging veins. The needle is virtually always the thing patients worry about most and notice least.
Step 4: The Session Itself
You’ll settle into a padded recliner in a private room designed for calm, not clinical sterility:
- Noise-cancelling headphones with soothing audio
- A soft eye mask
- A warm blanket
- Lighting you adjust
Session duration varies by condition:
- Mood disorders (depression, anxiety, PTSD, OCD): approximately 40 minutes of treatment plus 20 minutes of recovery
- Chronic pain conditions (fibromyalgia, migraines, EDS, post-surgical pain, complex pain): approximately 4 hours of treatment plus 2 hours of recovery
The extended pain protocol provides sustained NMDA blockade needed to meaningfully engage central sensitization — the neural amplification that keeps chronic pain active long after the original tissue damage has healed.
Vitals monitored continuously. Dr. Ho or a clinical team member stays present, checking in at regular intervals. First-session nervousness is expected — and nearly always resolved once patients experience the calm, controlled reality of the process.
Step 5: Post-Treatment Recovery
After treatment, you’ll rest comfortably while the effects gradually fade. Most patients feel clear-headed within 20 to 60 minutes.
Important logistics:
- You cannot drive — arrange a ride before arriving
- Keep the rest of the day low-key, with someone you trust nearby
- No major decisions, strenuous activity, or machinery until the next morning
- Expect a follow-up call from our team that evening or the next day
Serious adverse events at the sub-anesthetic doses we use are uncommon. Our team is always a phone call away if anything concerns you.
Step 6: Your Ongoing Treatment Plan
Ketamine response follows different timelines for different people. Some feel a significant shift after one session. Others improve gradually across several. Both trajectories are normal.
The typical structure:
- Initial series: 6 sessions over 2 to 3 weeks for mood conditions
- Dose calibration between sessions guided by your unique response
- Maintenance schedule adapted to your trajectory — weekly, biweekly, or monthly
- Reassessment at every visit to keep your protocol aligned with your evolving needs
This isn’t a rigid formula. It’s a responsive plan that adjusts with your data, your feedback, and the clinical evidence each session generates.
The Research Behind Ketamine Therapy
Ketamine’s place in psychiatry rests on decades of controlled, peer-reviewed evidence from some of medicine’s most respected institutions — not anecdote or early enthusiasm.
The landmark NIH trial found that a single ketamine infusion produced a 71% response rate in treatment-resistant depression, versus 0% with placebo — the most decisive efficacy separation ever recorded in a controlled psychiatric drug study (Zarate et al., 2006).
A multi-center replication using an active placebo to control for sedation confirmed a 64% response rate within 24 hours versus 28% in the control group, yielding a number needed to treat of 2.8 (Murrough et al., 2013).
A Science publication demonstrated the biological basis: ketamine directly reverses the synaptic damage chronic stress causes, stimulating new neural connection growth in the prefrontal cortex within 24 hours (Li et al., 2010).
For PTSD, a controlled trial at the Icahn School of Medicine at Mount Sinai showed that repeated ketamine infusions produced sustained, significant symptom improvement, with roughly two-thirds of participants reaching clinical response (Feder et al., 2014).
League City — a waterfront community of over 110,000 residents shaped by the precision culture of nearby NASA and Johnson Space Center — is a city that evaluates claims critically and expects solutions supported by verifiable data. This research delivers exactly that.
What the evidence consistently demonstrates:
- Ketamine engages the glutamate pathway — entirely separate from the serotonin, norepinephrine, and dopamine systems every conventional antidepressant targets
- Response rates of 60-71% in treatment-resistant depression far surpass the 10-15% achieved by switching between standard medications
- Synaptic regrowth begins within hours, confirmed by neuroimaging — the fastest structural brain change ever documented for a psychiatric treatment
- The same neural repair mechanism simultaneously addresses depression, anxiety, PTSD, OCD, chronic pain, and suicidal ideation

The medications you’ve tried all targeted the same three neurotransmitter systems — and for your brain, those systems weren’t where the damage lives. The glutamate pathway, where chronic conditions physically erode the synaptic connections that healthy mood, cognition, and pain regulation depend on, was beyond their pharmacological reach. Ketamine enters that pathway directly. It doesn’t modulate chemistry and hope for slow adaptation. It constructs new neural connections — often within a single session — and lets the structural restoration drive the improvement.

Commonly Asked Questions
Get Help NowHow quickly might I notice a difference after starting 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.
What safeguards are in place during ketamine treatment?
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.
How is a ketamine treatment course organized?
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 do patients typically experience during a 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.
Are there restrictions on what I can do after a ketamine 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.
Will the benefits persist between treatment sessions?
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.
Does ketamine work safely with other psychiatric 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.
Is a doctor's referral needed to begin ketamine therapy?
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.
