How can I tell if a pharmacy or medication is FDA-approved?

Only the manufacturers Novo Nordisk (for semaglutide products like Ozempic® and Wegovy®) and Eli Lilly (for tirzepatide products like Mounjaro® and Zepbound®) are FDA-approved to produce and sell these medications. Patients should always confirm that their prescriptions come from a licensed pharmacy sourcing directly from these companies—not from a compounding or online-only vendor claiming to make “semaglutide” or “tirzepatide.”
