Tirzepatide, a once-a-week shot acting on the GIP and GLP-1 receptors, is the active drug in Lilly's Zepbound (weight, sleep apnea) and Mounjaro (type 2 diabetes).

Harris County numbers and the brand question
CDC PLACES puts obesity at 37.3% and diagnosed diabetes at 13.2% of Harris County adults in 2023 [2]. The second figure matters because tirzepatide carries two labels. Mounjaro covers type 2 diabetes and, since August 2026, cutting major heart-event risk in high-risk adults with type 2 diabetes [6]. Zepbound covers chronic weight management and, for adults with obesity, obstructive sleep apnea that is moderate or severe; its label warns against pairing it with any other tirzepatide product [5]. A Houston patient with diabetes may get Mounjaro through a plan; someone treating weight alone usually ends up paying for Zepbound.

Hospital weight programs in Houston
Houston Methodist runs a weight center that pairs bariatric surgery with nonsurgical care; its page describes drug-based medical weight loss and medical nutrition therapy [15]. At Memorial Hermann, the NewStart service line has a medical weight management track that does not involve surgery [16]. Neither site posts a tirzepatide price, so ask about visit fees and insurance before you book. We name both as facts only; neither is ranked or endorsed.
LillyDirect from a Houston address
The steps are short. Your prescriber sends the Zepbound prescription to LillyDirect Pharmacy, a partner pharmacy calls to confirm details and savings, and then you pick home shipping or a Walmart pharmacy counter, both free [1]. The starter 2.5 mg strength is $299 and the 5 mg step is $399. The 7.5, 10, 12.5 and 15 mg strengths are $449 if each refill lands within 45 days; a later refill costs $499 (7.5 mg) or $699 (10 mg and up) [1]. The four-dose KwikPen, sold since February 23, 2026, costs the same as the vial but needs pen needles bought separately [8] [1]. Mounjaro lists at $1,112.16 per 28 days before insurance [7]. Visits and labs are billed apart from the drug. Every channel: tirzepatide cost guide and Zepbound cost page.
Trial numbers in short
On the 15 mg dose, SURMOUNT-1 participants without diabetes averaged 20.9% weight loss at 72 weeks, versus 3.1% for placebo [9]; in the SURMOUNT-5 head-to-head, tirzepatide averaged 20.2% against 13.7% for semaglutide [10]. Those are group averages. See tirzepatide results or Wegovy vs Zepbound.
Compounded offers in Texas
A compounded tirzepatide offer from a Houston clinic or med spa has no FDA approval behind it, and FDA does no review of its quality, safety or effectiveness [12]. FDA stopped tolerating routine 503A copies of tirzepatide in March 2025 and now accepts only patient-specific prescriptions where the prescriber records a significant difference for that patient [11]. By May 31, 2026, FDA held more than 730 adverse event reports tied to compounded tirzepatide [12]. Read compounded tirzepatide explained first.
Label warnings for Houston patients
Rats given tirzepatide grew thyroid C-cell tumors, which is the subject of its boxed warning. People with MEN 2, or whose family has a history of medullary thyroid carcinoma, are told not to take it. Belly pain that is intense and lingers may be pancreatitis: quit the shots and phone the prescriber, and do the same for hives, swelling or labored breathing. Adding insulin or a sulfonylurea raises hypoglycemia risk. The label says Zepbound ends when a pregnancy is found [13]. Life-threatening symptoms: 911.

What will a Houston cash buyer pay LillyDirect for Zepbound?
For cash buyers, LillyDirect's October 17, 2026 menu starts at $299 a month for the 2.5 mg starter and tops out at $449 for higher strengths refilled inside 45 days [1].
Do Houston hospitals offer medical weight loss with medication?
Will Texas Medicaid pay for Zepbound if I live in Houston?
Not for weight alone. KFF's January 2026 brief says Texas Medicaid covers some weight loss drugs, yet no GLP-1s prescribed for obesity [3].
What share of Harris County adults live with diabetes or obesity?
In 2023, by CDC PLACES estimates, diagnosed diabetes reached 13.2% and obesity 37.3% of Harris County adults [2].
Where do I confirm a Houston doctor's license?
The Texas Medical Board keeps the state's physician license records and offers a public search [4].
Is pharmacy-made tirzepatide still sold legally in Texas?
Only as a one-patient prescription where the prescriber records a significant difference for that person, under FDA's current policy; it remains unapproved by FDA [11].
How big is Houston?
The Census Bureau estimated 2,397,315 residents in the city of Houston on July 1, 2025 [14].
