GLP-1 Medicines: What Older Adults Should Ask Their Doctor

It is nearly impossible to get through a week without hearing about these medicines. Adult children mention them. Friends at the senior center are taking them. Ads for them are everywhere. So let us slow down and cover, in plain terms, what GLP-1 medicines are, why the decision is a medical one, and the questions worth writing down before your next appointment.

What “GLP-1” means, in plain English

GLP-1 stands for a hormone your own body makes in the gut after you eat. Among other things, it signals fullness, slows how quickly the stomach empties, and helps the body manage blood sugar. GLP-1 medicines imitate that hormone’s effects. Medicines in this class were developed first for type 2 diabetes, and some are also approved for chronic weight management and for certain other conditions. They are prescription medicines — most are taken as a weekly injection, one is available as a daily tablet — and brand names you may have heard include semaglutide and tirzepatide products.

That is the whole general picture. Everything after this paragraph — whether such a medicine fits a particular person, at what dose, with what other medicines, and with what risks — is individual, and it belongs to a clinician.

Why a clinician has to decide

• These medicines interact with a person’s other conditions and prescriptions. Slowed stomach emptying, for example, can affect how other oral medicines are absorbed — a real consideration for older adults who take several prescriptions on a schedule.
• There are people who should not take them, including people with certain thyroid tumor history and certain digestive conditions. Screening for that is a clinician’s job.
• They have real side effects — nausea and digestive troubles are the commonly reported ones — and the dose is normally raised gradually, with follow-up.
• Older adults have specific considerations, including appetite loss on top of an already-small appetite, and the importance of keeping muscle and strength while weight changes. A doctor who knows you can weigh those; an advertisement cannot.

Questions to bring to your doctor

Write these down. A short list in your pocket beats a blank mind in the exam room.

1. “Given my health history, is a medicine in this class something you would even consider for me — and if not, can you tell me why?”
2. “Which of my current prescriptions could be affected, and would any doses or timing need to change?”
3. “What side effects should I expect at the start, and which ones mean I should call you the same day?”
4. “How would we follow up — how often, and what would we check (weight, blood sugar, nutrition, strength)?”
5. “What happens if I stop? Is this a long-term commitment, and how do we think about that honestly?”
6. “What will this cost me, month after month? Is it covered by my plan, and what happens to my cost if coverage changes?”
7. “Are there approaches we should try first, or alongside — food, activity, sleep, other medicines?”

A good clinician will welcome these questions. If anyone — in an office or on a website — seems impatient with them, that tells you something.

A clear-eyed word about the ads

Much of the advertising in this area is for telehealth services and for compounded versions of these medicines, made by compounding pharmacies. Two facts every reader should hold onto:

• Compounded medicines are not FDA-approved. The FDA has not reviewed compounded versions for safety, effectiveness, or quality the way it reviews approved brand-name medicines. A compounded product is not “the same as” the brand-name drug, whatever an ad implies, and it is not a generic version of it — there are no FDA-approved generic versions of these medicines.
• Price-first advertising skips the screening. Any service that leads with a price and a promise, and treats the medical consultation as a formality, has its priorities showing. A legitimate service leads with evaluation: your history, your other medicines, and the real possibility that the answer is “not for you.”

The U.S. Food and Drug Administration has warned repeatedly about misleading claims in this market, and about dosing errors and counterfeit products bought from questionable online sources. Buy prescription medicine only through legitimate channels, on a real prescription, from a licensed pharmacy.

The bottom line

GLP-1 medicines are a significant medical development, and for some people — decided carefully, with a clinician who knows them — they are part of good care. For other people they are a poor fit, and only that same conversation can sort out which is which. If the subject is on your mind, the right next step is not a website checkout. It is the list of questions above, in your pocket, at your next appointment.
