Record provenance

Call to confirm current services, availability, and pricing.

What bariatric medicine means

Bariatric medicine centers on the medical (non-surgical) treatment of obesity: supervised weight-loss programs, prescription medications including GLP-1 receptor agonists, and long-term metabolic follow-up. Some bariatric practices also coordinate with or provide weight-loss surgery; ask whether this clinic's program is medical, surgical, or both.

Asking about GLP‑1 treatment at Jennifer Mulligan

Call (617) 726-2000 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.
