A practical, safety-first checklist for anyone in Las Vegas considering semaglutide or tirzepatide, with the answers a good clinic should be willing to put in writing.
Updated on: 2026-08-27
Before you pay for or inject a single dose of a GLP-1 medication, you should be able to name the clinician prescribing it, know whether the drug is FDA-approved or compounded, and understand exactly how your dose will be measured and increased. If a clinic can't answer those three things clearly, that's your signal to slow down. Everything else below builds on that.
GLP-1 weight loss usually means prescription semaglutide (the active ingredient in Wegovy) or tirzepatide (a GIP/GLP-1 medication sold as Zepbound). These are prescription treatments meant to work alongside changes in eating and activity, not standalone injections you buy and forget about. The questions that follow are the ones I'd want answered before starting, and they're the same ones a careful clinic will expect you to ask.
Am I medically eligible, and what's the actual goal?
Ask for your current BMI and whether you meet standard prescribing criteria. For adults, FDA-approved chronic weight-management indications generally start at a BMI of 30 or greater, or 27 or greater with at least one weight-related condition like high blood pressure, type 2 diabetes, high cholesterol, or sleep apnea. The NIDDK eligibility framework uses the same general thresholds.
If your BMI is below the usual threshold, ask for the clinical reasoning. A responsible clinic ties treatment to a real diagnosis and a measurable goal, not just a number you want to hit on the scale. Also ask what non-medication changes should go alongside the medication. If nobody mentions food, movement, or sleep, that tells you something about how the clinic thinks about weight.
Who is actually evaluating and prescribing for me?
Get the name, credential, and Nevada license number of the prescriber. Then ask whether you'll meet that person or only a medical assistant or a platform-affiliated clinician you never see again.
Nevada law generally requires a provider who diagnoses, manages care, or prescribes for a patient in Nevada to hold a valid Nevada license or authorization. You can verify a license and check for disciplinary history through the Nevada State Board of Medical Examiners. For telehealth specifically, ask where the prescribing clinician is licensed and where the medication-management visit is legally taking place.
One more question that matters more than people expect: who's reachable after hours if you have severe vomiting, abdominal pain, or an allergic reaction? A prescription without a phone number attached to it isn't a plan.
Exactly which medication and formulation am I getting?
This is the question I'd refuse to skip. Ask the clinic to name the product precisely:
- Is it Wegovy, Zepbound, or a compounded product?
- What's the generic name and strength?
- Will you receive a manufacturer-sealed pen or vial, or something a pharmacy mixed?
- Which pharmacy dispenses it, and is that pharmacy state-licensed?
- Is it FDA-approved for weight management, or prescribed off-label or compounded?
FDA-approved products go through review for safety, effectiveness, and manufacturing quality. Compounded drugs do not. The FDA's guidance on unapproved GLP-1 drugs says compounded versions should generally be reserved for situations where an FDA-approved product can't meet a patient's medical need. Be cautious with any clinic that describes a compounded product as "the same as" Wegovy or Zepbound. The FDA also warns that semaglutide sodium and semaglutide acetate are different active ingredients from those in approved semaglutide drugs, and says it isn't aware of a lawful basis for using them in compounding.
Nevada has also moved to restrict compounding of these injections, so if a local clinic offers a compounded version, ask them to explain the legal and medical basis in writing.
How will you rule out the conditions that make this risky?
Both Wegovy and Zepbound carry a boxed warning about thyroid C-cell tumors seen in rodents. Both are contraindicated in people with a personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2 (MEN 2), and in anyone who's had a serious allergic reaction to the drug or its ingredients. A clinic should ask about all of that before writing anything.
Bring up your full picture:
- History of pancreatitis, gallstones, or gallbladder disease
- Kidney or liver disease, diabetic retinopathy, or type 2 diabetes
- Severe gastroparesis or another stomach-emptying problem
- Use of insulin, a sulfonylurea, or another GLP-1 medicine
- Any planned surgery, sedation, or endoscopy
- Pregnancy, trying to conceive, or breastfeeding
The current Wegovy prescribing information warns about pancreatitis, gallbladder disease, low blood sugar, acute kidney injury from dehydration, severe gastrointestinal reactions, and delayed stomach emptying. If a clinic hands over medication without asking about any of this, that's a red flag on its own.
What baseline evaluation and labs do I need?
Ask what gets recorded before treatment: weight, BMI, waist, blood pressure, pulse, and a real medical history. Then ask which labs apply to you specifically and why.
There's no single "GLP-1 lab panel" that fits everyone. Testing should follow your conditions, medications, and pregnancy possibility. Depending on your history, that might include blood glucose or A1C, kidney function, liver tests, lipids, or a pregnancy test. A good clinic can explain what would make them delay or decline treatment, not just what would make them say yes.
Partida Corona Medical Center's public GLP-1 information describes an evaluation that includes medical history, lab work, and a physical exam, with injection training and follow-up built in. That's the shape you want. Ask them to specify exactly what each component covers for you, because the details are what protect you.
What's the starting dose, and how will you increase it?
Ask for the starting dose, how long you'll stay there, and what symptoms would make them hold or delay an increase. For Wegovy injection, the label starts at 0.25 mg once weekly and steps up roughly every four weeks through 0.5 mg, 1 mg, and 1.7 mg before a usual maintenance dose of 2.4 mg, and it allows delaying escalation when a dose isn't tolerated. Zepbound is also titrated gradually, up to a maximum of 15 mg once weekly per its FDA label.
Insist on a written dose in both milligrams and the actual device setting or volume. You should never have to guess a dose from "units" on a syringe without clear instructions. Also ask what to do if you miss a dose or stop for a few weeks and restart, and how they'll prevent double-dosing if you're switching from another GLP-1 drug.
How will you teach me to use, store, and dispose of it?
Ask whether someone will demonstrate the injection and watch you do it. Ask how milligrams, milliliters, and syringe units line up for your specific product, how to store it at home, and how to dispose of used needles.
The FDA has reported dosing errors with compounded injectable semaglutide, including patients measuring wrong amounts, with some cases requiring hospitalization. The agency also warns that injectable products arriving warm or without proper refrigeration shouldn't be used, because storage problems affect quality. For any compounded product, get the pharmacy's written concentration (milligrams per milliliter) rather than a verbal "inject 25 units."
What side effects are expected, and which mean emergency care?
Common reactions include nausea, diarrhea, vomiting, constipation, and abdominal pain. In adult Wegovy injection trials, nausea occurred in 44% of patients on the 2.4 mg dose, diarrhea in 30%, vomiting in 24%, and constipation in 24%. Those are population figures, not a prediction for you, but they're worth knowing before you start.
Ask which symptoms mean call the same day, and which mean stop and go to the ER. Get medical advice promptly for:
- Persistent or severe abdominal pain, especially radiating to the back (possible pancreatitis)
- Severe vomiting or diarrhea with reduced urination or dizziness (dehydration and kidney risk)
- Right-upper-abdominal pain, fever, or jaundice (gallbladder)
- Facial or throat swelling, trouble breathing, or widespread hives (serious allergic reaction)
- A neck lump, persistent hoarseness, or trouble swallowing
If you use insulin or a sulfonylurea, ask specifically about low-blood-sugar symptoms.
How will you monitor me after the first prescription?
Ask when the first follow-up is and how often visits happen during dose escalation. A credible plan tracks weight, blood pressure, pulse, hydration, symptoms, and relevant labs. It also defines what counts as an inadequate response or a reason to stop.
Partida Corona's public materials say it offers regular follow-ups to track progress and adjust dosing. Pin down the actual interval, for example whether they'll review you every four weeks during titration, and what the follow-up fee includes. Ask how they handle rapid weight loss or muscle loss, and whether they'll address protein intake, resistance training, and sleep, not just the number on the scale.
What about pregnancy, contraception, and surgery?
Ask whether you should take a pregnancy test first, how long before trying to conceive you should stop, and what to do if you become pregnant while taking it. The Wegovy label advises stopping semaglutide at least two months before a planned pregnancy because of its long half-life.
Tirzepatide can delay gastric emptying and may affect absorption of oral medicines, including some contraceptives, and its Zepbound labeling warns about rare pulmonary aspiration during general anesthesia or deep sedation. Don't stop the medication on your own before a procedure. Instead ask: what's your procedure-specific plan, and who do I contact?
What will the full cost be, itemized?
Get a line-by-line answer: consultation fee, labs, follow-up visits, medication, injection supplies, and what happens if you need a dose change or urgent visit. Ask whether the price changes when the dose increases, whether there are membership, shipping, or cancellation fees, and how much notice cancellation requires.
Don't read a low advertised price as proof of equivalent care. The FDA lists unusually deep discounts, absent screening, no identifiable prescriber, damaged packaging, and unclear pharmacy information as warning signs in the online compounded-drug market. This is one place where affordability and transparency should travel together. A clinic that's genuinely low-cost has no reason to hide the breakdown, and Partida Corona Medical Center's stated position on all-inclusive pricing with no hidden fees is the standard to hold any clinic to.
What's the plan if I stop?
Ask whether this is short-term or chronic treatment, what would lead you to taper or switch, and what support you'll get afterward. In the STEP 1 semaglutide extension, participants who stopped treatment regained roughly two-thirds of the weight they'd lost over the following year. That's not a guarantee about you, but it's the reason maintenance planning matters more than a fast start.
Ask how they'll monitor weight, blood sugar, blood pressure, and appetite after you stop, and how your records transfer if you change insurance or move.
Red flags worth pausing over
| Warning sign | Why it matters |
|---|---|
| Medication offered without a clinician-led evaluation | Skips the screening that catches contraindications |
| You can't name the prescriber | No accountable, verifiable clinician |
| Clinic won't identify the pharmacy or manufacturer | You can't verify what you're injecting |
| Product called "same as Wegovy/Zepbound" without saying it's compounded | Compounded drugs aren't FDA-reviewed |
| Instructions use "units" with no stated concentration | Leads to dosing errors |
| Dose increased despite vomiting, dehydration, or severe pain | Ignores your safety signals |
| No emergency contact or follow-up plan | You're on your own between doses |
| Pressure to prepay a long package before evaluation | Money before medicine |
| Medication arrives warm, damaged, or mislabeled | Storage and quality problems |
| A guaranteed percentage of weight loss | No responsible clinic promises this |
FAQ
Is compounded semaglutide the same as Wegovy?
No, and it's worth being precise here. Wegovy is an FDA-approved product reviewed for safety, effectiveness, and manufacturing quality. Compounded semaglutide is not FDA-approved, and the FDA doesn't review it before it reaches you. The concentration, container, and instructions can vary between pharmacies. If a clinic offers a compounded version, ask why an approved product can't meet your need, who compounded it, and at what concentration.
Do I need lab work before starting a GLP-1 medication?
You should have a real medical evaluation, but there's no universal panel that fits everyone. The right tests depend on your conditions, medications, and whether pregnancy is possible. A clinic that prescribes with no history, medication review, or exam is cutting a corner that exists for your safety.
How fast will I lose weight?
Any clinic promising a specific percentage is overselling. Response varies by person, dose tolerance, and what you're doing alongside the medication. A better question is how the clinic defines success for you and what they'll do if the medication isn't working or isn't tolerated.
What happens if I stop taking it?
Weight regain is common after stopping, which is why these medications are framed as chronic weight management rather than a short course. Ask your clinic what the post-treatment plan looks like before you begin, not after.
A closing note for Las Vegas readers
