What to actually ask your doctor about Ozempic, Wegovy, or Zepbound.

Most patients walk into the GLP-1 conversation with two questions in mind: can I get it, and how much does it cost. Both matter. But there are nine other questions that determine whether you'll actually tolerate the drug, stay on it long enough to see results, and avoid the contraindications that send some patients to the ER. Here's the field-tested checklist most patients don't think to ask — and what the right answers sound like.

The verdict in three sentences

The questions that matter most.

Eligibility and cost are the obvious questions. The less-obvious-but-more-important ones are about safety history, side-effect management, dose titration, what happens if you can't tolerate it, and what happens when you stop. Most patients don't ask these until they're already on the drug and something's gone wrong.

The right doctor's answers should be specific, not vague. "We'll figure it out" is not a plan. "If you're nauseated past week 3, we drop you to 0.5mg for an extra cycle, and if it doesn't resolve by week 8 we consider switching to tirzepatide" is a plan. Specificity tells you whether your prescriber has actually titrated dozens of patients on this class — or is reading the package insert in real time.

Before the appointment

Two things to bring with you.

A real GLP-1 conversation goes faster and lands better if you arrive with two things in hand. Skip these and most of the appointment time gets spent gathering information you already had.

1. Your medical history, condensed

Specifically: your family history of medullary thyroid carcinoma (MTC) or Multiple Endocrine Neoplasia type 2 (MEN2), any personal history of pancreatitis or gallbladder issues, current medications (especially insulin or sulfonylureas if you're diabetic), pregnancy plans within the next 12 months, and your weight trend over the last year. These are the things that change the prescriber's calculus most.

2. Your insurance situation

Know whether your plan covers GLP-1s for your indication (T2D vs obesity vs OSA vs CV indication), what the prior authorization requirements are, and whether your plan has a step-therapy rule (must try cheaper drugs first). Most insurance plans publish this in their formulary documents. If your doctor doesn't know your plan's specifics, that's the first thing that needs to get figured out — it determines half the path forward.

The 9 questions

The questions most patients don't think to ask.

Each one matters. Each one has a specific kind of answer that tells you whether your prescriber is doing thoughtful medicine or just writing prescriptions.

Question 01
"Given my full medical history, is there anyone in this drug class I shouldn't take?"
Why this matters
The boxed warning on all GLP-1s contraindicates personal or family history of medullary thyroid carcinoma (MTC) or MEN2. Less prominent: a history of pancreatitis is a relative contraindication; severe gallbladder disease changes the calculus; and there are specific Semaglutide / Tirzepatide differences worth understanding.
Good answer sounds like
"Let me check your family history of thyroid issues and your pancreatitis history. If those are clear, both Semaglutide and Tirzepatide are reasonable starting points. If you have an MTC family history, neither is appropriate and we'd look at different approaches."
Walk-away signal
"They're all the same; whatever your insurance covers." That's not a clinical answer.
Question 02
"What's your specific titration plan, and what triggers a dose change?"
Why this matters
Every GLP-1 starts at a low dose and steps up every 4 weeks. Nausea, fatigue, and constipation are dose-dependent and usually subside if you give your body time. But the schedule isn't a recipe to follow blindly — if you're hitting nausea hard at 0.5mg Semaglutide, going up to 1mg on schedule will make it worse.
Good answer sounds like
"Standard schedule is 4 weeks at each dose: 0.25, 0.5, 1, 1.7, 2.4 for Wegovy. If you have significant nausea, we stay an extra cycle at the dose you tolerate. If you can't tolerate even 0.25, we sometimes split the dose or switch to a different agent."
Walk-away signal
"Follow the package insert."
Question 03
"What side effects should I expect, and when do I call you vs. tough it out?"
Why this matters
Most GLP-1 side effects are uncomfortable but harmless: nausea, fatigue, constipation, mild abdominal discomfort. A few are serious: severe abdominal pain radiating to the back (pancreatitis), persistent vomiting, signs of gallbladder attack, and very rarely, bowel obstruction (ileus). You should know which is which.
Good answer sounds like
"Nausea peaks days 2–5 after each dose escalation. Eat smaller meals, avoid greasy foods. Call me if you have severe upper-belly pain that goes through to your back, vomiting that won't stop, signs of gallbladder attack, or anything that looks like a bowel blockage. Those need the ER, not a wait-and-see."
Walk-away signal
"You'll be fine. Try to push through."
Question 04
"What does the insurance prior-auth process actually look like for my situation?"
Why this matters
Most weight-loss prescriptions require prior authorization. Some plans require documented BMI 30+ (or 27+ with comorbidity), documented diet history, and step therapy through cheaper drugs first. Some plans cover Wegovy for cardiovascular indication but not for weight alone. The denial letter (when it comes) usually tells you exactly what was missing.
Good answer sounds like
"Your plan requires BMI 30+ or 27+ with a comorbidity, plus 6 months of documented diet attempts. I'll write the prior auth with your records; if denied, the letter will tell us what's needed for the appeal. Most denials at first pass are missing one document we can resubmit."
Walk-away signal
"Call your insurance and figure it out yourself."
Question 05
"If insurance won't cover it, what are my legitimate cash-pay options in 2026?"
Why this matters
The cash-pay landscape shifted dramatically in 2025–2026. Manufacturer direct-to-consumer programs — Lilly Direct for Zepbound (around $500/month for vials) and NovoCare for Wegovy ($349/month) — are now the lowest legitimate prices. Compounded versions are a different conversation (see our analysis on what compounded GLP-1 actually means now).
Good answer sounds like
"If insurance denies, NovoCare gets you Wegovy at $349/month cash-pay. Lilly Direct gets you Zepbound vials around $500. Both are legitimate brand-name medication from the manufacturers themselves. Compounded versions are no longer permitted under the shortage exception."
Walk-away signal
"I work with a compounding pharmacy that does it cheap." (See: this is the 2026 red flag.)
Question 06
"Should it be Semaglutide or Tirzepatide for me specifically?"
Why this matters
Both are FDA-approved for diabetes and weight loss. Tirzepatide produces more weight loss on average in head-to-head trials. Semaglutide has the cardiovascular indication (SELECT trial); Tirzepatide has the obstructive sleep apnea indication (SURMOUNT-OSA). Tolerability and insurance coverage often decide the choice in practice. Our full GLP-1 comparison breaks this down.
Good answer sounds like
"For weight loss alone, Tirzepatide produces more on average. If you have established cardiovascular disease, Semaglutide has the CV approval. If you have moderate-to-severe sleep apnea, Tirzepatide is the only one approved for that. Your insurance and what you can tolerate at higher doses also play in."
Walk-away signal
"Whichever the rep brought samples of." (Yes, this still happens.)
Question 07
"What happens if I can't tolerate the drug?"
Why this matters
Roughly 10–20% of patients can't tolerate a full dose due to GI side effects. The right response isn't "tough it out forever" or "stop entirely." It's a planned series of moves: dose reduction, splitting doses, switching agents within the class, or eventually concluding the class isn't for you.
Good answer sounds like
"Most intolerance is dose-related; we drop you back to the previous dose for an extra cycle. If you still can't tolerate it at maintenance, we sometimes try switching from Semaglutide to Tirzepatide (or vice versa) since tolerability differs. If neither works, we have other approaches — you're not stuck."
Walk-away signal
"Just push through and you'll get used to it."
Question 08
"What happens when I want to stop?"
Why this matters
Stopping a GLP-1 abruptly is associated with significant weight regain — trial data shows roughly two-thirds of lost weight returns within a year of discontinuation. Some patients stop because they hit their goal; some because of side effects; some because of cost. The plan for what comes next matters. There's also pregnancy planning: because of Semaglutide's long half-life, a 2-month washout before conception is generally recommended.
Good answer sounds like
"Most patients stay on a maintenance dose long-term. If you stop, we taper rather than cut cold-turkey, and you'll need a lifestyle plan to maintain — about 2/3 of lost weight comes back within a year on average. If you're planning pregnancy, we stop at least 2 months before conception."
Walk-away signal
"You'll know when it's time."
Question 09
"How do we monitor progress, and how often?"
Why this matters
A real follow-up cadence catches problems early. Some patients regain at month 9 because their dose isn't right; some have liver markers that need watching; some have unaddressed nutrient deficiencies because they're eating much less. Without scheduled follow-up, all of this slides.
Good answer sounds like
"Check-in at week 4 to confirm tolerability, every 3 months thereafter for the first year. Labs at baseline and at 6 months: liver, kidney, glucose, lipids, B12. Weight and waist circumference at each visit."
Walk-away signal
"Come back if something goes wrong."
Red flags to walk away from

When the answers tell you to find a different doctor.

A few specific signals that the prescriber isn't a real partner for the GLP-1 journey — regardless of what their marketing says:

Walk away if you hear any of these

1. "Whatever your insurance covers." Without considering your medical history, contraindications, or what you're treating.
2. "Just follow the package insert." If they're not adapting the titration to you, they're not titrating — they're publishing.
3. "We can get you compounded if insurance denies." In 2026, this is the prior-shortage-exception loophole that's mostly no longer legitimate.
4. "You'll be fine." If they can't tell you which side effects are normal vs. ER-worthy, they haven't titrated enough patients.
5. "Come back if something goes wrong." No scheduled follow-up plan means no plan.
6. "We have an in-house pharmacy that handles everything." Vertical-integration arrangements can be legitimate, but they should be disclosed and you should be able to fill the script elsewhere if you want.

If you only remember three things from this article, remember these three categories of question — and ask one from each:

Those three questions, asked clearly and with the documents in hand to support them, separate the appointments that go well from the ones where you walk out unclear about what you're doing or why.
