Tirzepatide in San Antonio — Medically Directed GLP-1/GIP Therapy
Dual GLP-1/GIP therapy, medically prescribed and titrated with muscle-preserving support.

About Tirzepatide
Considered care, calibrated to you.
Tirzepatide in San Antonio is the newest generation of medical weight-loss therapy — a dual agonist that activates both the GLP-1 and GIP receptors rather than GLP-1 alone. In head-to-head clinical data, that dual mechanism produces higher average weight reduction than semaglutide at comparable treatment durations, which is why many patients specifically ask for it by its brand names, Mounjaro and Zepbound. At THEIA in Stone Oak, tirzepatide is prescribed only after a complete medical evaluation with our Medical Director: medical history, current medications, BMI and comorbidity assessment, and baseline labs when clinically indicated. Dosing begins low and escalates on a schedule designed around your tolerance, because the single most common reason patients abandon tirzepatide is a titration pace that outruns their gut. We follow up every four weeks during escalation, adjust when nausea or fatigue appear rather than telling you to push through, and build muscle-preserving nutrition into the plan from week one. Patients travel to us from Stone Oak, Sonterra, Hollywood Park, Alamo Heights and greater North San Antonio for care that treats weight as a medical condition, not a package.
Benefits
What this treatment delivers.
- ◈Dual GLP-1/GIP mechanism — higher average weight reduction than single-agonist therapy
- ◈Prescribed and monitored under our Texas-licensed Medical Director
- ◈Individualized titration schedule built around your tolerance, not a fixed calendar
- ◈Baseline and interval labs when clinically indicated
- ◈Muscle-preservation protocol — protein targets and resistance training guidance
- ◈Side-effect management between visits, not just at appointments
- ◈Structured maintenance planning so results hold after the escalation phase
- ◈Discreet Stone Oak setting with private consultation rooms
The Experience
What happens at THEIA.
- 01
Complimentary consultation & personalized assessment
Complete history, medication reconciliation, BMI and comorbidity review with our clinical team — in person or by telemedicine.
- 02
Labs & candidacy review
Baseline metabolic panel, A1c and thyroid screening when clinically indicated, plus review of contraindications including personal or family history of medullary thyroid carcinoma or MEN2.
- 03
Starting dose
Therapy typically begins at 2.5 mg weekly — a non-therapeutic starting dose intended purely to build tolerance before escalation.
- 04
Titration every four weeks
Dose increases only when the previous step is well tolerated. Escalation pauses are normal and often improve long-term adherence.
- 05
Maintenance & muscle protection
Once your effective dose is reached, we shift focus to holding results: protein intake, resistance training and the lowest dose that maintains them.
Is this for me?
Ideal candidates.
- —Adults with BMI ≥ 30, or BMI ≥ 27 with weight-related comorbidities
- —Patients who plateaued or tolerated semaglutide poorly and want to switch mechanisms
- —Patients with insulin resistance, prediabetes or metabolic syndrome (clinical assessment required)
- —Patients who want structured medical supervision rather than a mail-order prescription
Tirzepatide at THEIA is prescribed exclusively by our Medical Director following a complete medical evaluation and good faith examination. Mounjaro and Zepbound are referenced only to identify the active molecule. Tirzepatide is not appropriate for everyone and is contraindicated in patients with a personal or family history of medullary thyroid carcinoma or MEN2. Individual results vary; no specific amount of weight loss is promised.
Questions
Frequently asked.
Do you prescribe tirzepatide in San Antonio?
Yes. THEIA prescribes tirzepatide — the active molecule in Mounjaro and Zepbound — from our Stone Oak location at 238 N Loop 1604 W, Suite 206. Every prescription follows a medical evaluation and good-faith examination with our Medical Director.
Is tirzepatide better than semaglutide?
In clinical trials tirzepatide produced higher average weight reduction — roughly 20% of body weight versus about 15% for semaglutide over comparable periods. That does not make it the right choice for everyone: cost, tolerability, medical history and coverage all matter. We select the molecule at your consultation rather than defaulting to one.
How much does tirzepatide cost in San Antonio?
Tirzepatide programs generally cost more than semaglutide because the medication itself is more expensive at equivalent dosing stages. Our program is quoted as a bundled monthly medical plan covering medication, clinical visits, titration monitoring and follow-up, with transparent pricing given at consultation and no hidden fees. FSA/HSA may apply.
What are the side effects of tirzepatide?
The most common are gastrointestinal — nausea, reduced appetite, constipation or loose stools — typically concentrated in the days after a dose increase and usually transient. Rare but serious risks including pancreatitis and gallbladder disease are reviewed at consultation and monitored throughout care.
How fast will I lose weight on tirzepatide?
Most patients notice appetite change within the first two weeks, though the starting dose is not intended to produce meaningful weight loss. Clinically significant reduction typically begins once you reach therapeutic dosing around weeks 8 to 12. Individual results vary.
Can I switch from semaglutide to tirzepatide?
Yes, and it is a common request after a plateau or poor tolerance. Switching is not dose-for-dose — we restart tirzepatide at its own titration schedule, sometimes with a modified ramp based on your prior exposure. This must be medically directed.
Will I lose muscle on tirzepatide?
Rapid weight loss on any GLP-1 includes lean mass unless it is actively defended. Our program sets protein targets and encourages resistance training from the start, and Body Tone sessions are available for patients who want additional muscle stimulus during their program.
What happens if I stop tirzepatide?
Appetite signaling returns and weight regain is common without a maintenance plan. We plan for this from the beginning — building nutrition and activity habits during treatment, and using lower-dose or extended-interval maintenance when appropriate.
