5 Questions to Ask Before You Start a Weight Loss Medication

Why does the source of the question matter more than the answer to "does it work"?

Because "does it work" is largely settled. GLP-1 class medications produce meaningful weight loss for most people who take them as prescribed. That's not the part anyone needs to interrogate anymore.

What's unsettled, and what varies enormously between one prescriber and the next, is everything around the medication: who's watching for problems, where the drug actually comes from, and what the plan is once the easy part (losing weight) turns into the hard part (keeping it, or deciding what's next). Those are the questions that separate a program from a subscription.

Here are five worth asking before you start, with a plain answer for each.

1. Who is actually supervising this, and can they see my labs?

A lot of telehealth weight loss services run on an intake questionnaire and a video call that lasts a few minutes. That can technically satisfy "a prescription was written," but it's a different thing from ongoing supervision.

Ask directly: will the same person or team be reviewing my bloodwork over time, or does each refill go through a different reviewer with no history on me? Yale Medicine's guidance on getting started with GLP-1 medications is explicit that this is meant to be managed as an ongoing relationship, not a one-time transaction — obesity is treated as a chronic condition, and the clinicians quoted in that piece specifically warn against getting a prescription and walking away. If nobody can answer who is actually looking at your data between visits, that's your answer.

2. What happens if side effects show up, and who do I call?

Nausea, constipation, and a feeling of early fullness are common early on, and most people adjust. But "most people" isn't "everyone," and the medications carry real contraindications: a personal history of pancreatitis, a personal or family history of medullary thyroid carcinoma or MEN2 syndrome, and pregnancy are standard exclusions cited by academic medical centers offering this treatment.

Before starting, you should know exactly who you contact if something feels wrong, on what timeline they'll respond, and whether that's a real person who knows your case or a general support inbox. Dosing increases typically happen on a monthly cadence if side effects are tolerable and weight loss isn't excessive — if a service is pushing you up in dose faster than that without checking in, that's worth questioning.

3. Where is this medication actually coming from?

This is the question most people skip, and it's the one the FDA has been most vocal about.

In a September 2026 update, the FDA reported that compounded versions of these medications "do not undergo FDA's review for safety, effectiveness and quality before they are marketed." Through May 31, 2026, the agency had logged 990 adverse event reports tied to compounded semaglutide and more than 730 for compounded tirzepatide, some resulting from patients self-administering incorrect doses and others from miscalculated compounding. The FDA has also received complaints of multi-dose vials arriving warm or with inadequate ice packs, and has identified counterfeit compounded products carrying false pharmacy information.

Two compounds are worth naming specifically because federal law treats them differently: retatrutide and cagrilintide "cannot be used in compounding under federal law" and have not been proven safe for any condition, according to the FDA. Neither is something a compliant compounding pharmacy can legally provide, regardless of how it's marketed. Vitality Dartmouth does not prescribe or compound either of these.

Practical red flags the FDA points to: prices that seem too good to be true, no requirement for a prescription from a licensed prescriber who has actually evaluated you, and packaging with damaged seals, missing lot numbers, or spelling errors on the label. If a 28-day-old opened vial is still being used past that window, that's also a storage and contamination risk the FDA specifically warns about.

4. What's the plan for month 12, 18, and beyond?

Ask this before you start, not after you've already lost the weight. A program that has no answer for "what happens when the fast part is over" doesn't have a real plan, it has a prescription.

That plan should include: a taper or continuation decision made with your prescriber and based on your labs and goals, not a default that just runs your card every month; a strength training component, because muscle is what determines whether the weight that comes back is fat or lean mass; and a schedule for repeat bloodwork so anyone involved can actually tell what's changing, not just what the scale says.

5. What would an in-person visit catch that a questionnaire can't?

A body composition change a scale doesn't show. A blood pressure trend across three visits instead of one reading. The difference between someone who's adjusting well to a dose and someone who's quietly losing more lean mass than fat. A conversation about the training and protein side of this, which no telehealth intake form asks about, because nobody there is coaching you through it.

None of that means telehealth is wrong for everyone. It means it's worth being honest with yourself about which one you're actually signing up for.

How does Vitality Dartmouth answer these five questions?

Directly, because we think you should be able to ask any provider these same five questions and expect a real answer.

Who's supervising: our collaborating NP or MD reviews your case and labs directly, and I'm the same person coaching your training from the first conversation through month 18 and beyond. Side effects: you have a real contact, not a support ticket queue. Sourcing: our collaborating provider prescribes FDA-approved medication through licensed channels; we don't prescribe or compound retatrutide or cagrilintide, both of which are restricted from compounding under federal law regardless of how a service brands them. The long-term plan: your dosing, tapering, and continuation decisions are made with lab data in front of us, alongside a resistance training program built to protect the muscle mass that determines what your body looks like after the medication does its job. In-person: you're in Dartmouth, in a room, on a schedule that doesn't reset with every refill.

To be clear about scope: I'm a registered nurse. I build the program, coach the training, and translate the data. I don't prescribe or diagnose. Our collaborating NP or MD writes every prescription and orders every lab.

Does this look different on the SouthCoast?

The underlying medical questions are the same everywhere. What's different locally is whether you can actually get an answer to them.

Dartmouth, New Bedford, Westport, Fairhaven, and Fall River all have healthcare access, but a lot of the people who come through our door tried a national telehealth platform first and never met the person reviewing their case. Being a local, in-person clinic means the person who answers these five questions for you in September is the same person answering them in March.
