Primary care and GLP-1 treatment

Family and internal medicine providers manage weight as part of whole-person care. A primary-care-based GLP-1 program can be a good fit if you want your weight, labs, blood pressure, and other medications managed in one place — and it often simplifies insurance coverage.

Asking about GLP‑1 treatment at Annette Chang

Call (734) 647-5871 and ask these questions before booking:

  • ✓Do you currently prescribe GLP‑1 medications (semaglutide or tirzepatide) for weight loss?
  • ✓Do you work with my insurance, or is the program cash-pay — and what does a month cost all-in?
  • ✓Is the medication a brand-name product, or compounded by a compounding pharmacy?
  • ✓What follow-up is included for dose changes and side effects?

About compounded medications: A compounded drug is prepared by a state-licensed compounding pharmacy. Compounded drugs are not FDA-approved and are not reviewed by the FDA for safety, effectiveness, or quality, and they are not the same as FDA-approved generic drugs. Ask any practice which it dispenses and which pharmacy prepares it.
