Getting GLP-1 care from your primary care clinician

If you already see a family medicine or internal medicine clinician, they are the cheapest and often the safest place to start. They have your history, your labs and your medication list, and the visit runs through insurance like any other. The catch is that not every primary care clinician will prescribe, and the ones who do have limited time.

Why this model is under-used

People assume a GLP-1 needs a specialist or a dedicated program. It does not. The AGA 2022 guideline is written for the clinicians who see most adults with obesity, which is primary care. Your clinician already knows whether your blood pressure has been creeping, whether your kidney function is normal, whether you take a sulfonylurea, and what happened the last time you tried to lose weight. That is most of a good intake before you have said a word.

How to ask

Book a visit for it rather than raising it in the last minute of a visit about something else. Say what you want to discuss: whether you are a candidate for a GLP-1, what it would involve, and whether the practice manages it. Bring the preparation list. If the clinician does not prescribe these drugs, ask for a referral to someone who does, and ask whether they will still do the labs and blood pressure checks while another clinic prescribes. Many will.

What a primary care visit can do

• Screen properly. The label contraindications (personal or family history of medullary thyroid carcinoma, MEN 2, serious hypersensitivity) and the warnings (pancreatitis, gallbladder disease, kidney injury from dehydration, hypoglycemia with insulin or a sulfonylurea) are all in the Zepbound and Wegovy labels, and a primary care clinician checks them against a record they already hold.
• Adjust the other drugs. If you have type 2 diabetes, the same clinician can lower an insulin or sulfonylurea dose when the GLP-1 starts, and can follow your A1c on the ADA schedule: at least twice a year, and every 3 months when treatment has just changed.
• Bill insurance for the visit at a normal copay, and submit the prior authorization for a brand product if your plan covers one. See insurance-based vs cash-pay clinics.
• Keep one record. Everything is in the chart your other clinicians read.

What it does less well

• Time. A 15 or 20 minute visit does not leave room for nutrition counselling or a long discussion of options. Ask whether the practice has a dietitian or a nurse-led follow-up.
• Titration visits. Primary care may not schedule a check at every dose step. Agree the follow-up plan explicitly; how follow-up should work gives a template.
• Speed of refills and dose changes. Portal messages can take days. Ask how dose changes are handled between visits.
• Compounded products. Most primary care practices prescribe brand products to a retail pharmacy. If that is not what you want, say so early.

When to move on

The AACE/ACE 2016 guideline expects follow-up on response and adverse effects and an escalation of care when the response is inadequate. If your clinician cannot offer titration checks, is not comfortable with side-effect management, or you have a complication that needs a specialist, a referral to an in-person obesity medicine clinic or a hybrid arrangement is the next step. Ask for the records to travel with you; how to switch clinics explains your right to them.
