Prescription weight-loss drugs

Medicines not approved by the FDA

The Food and Drug Administration has concerns about people getting and using weight-loss drugs from compounding pharmacies. These pharmacies make versions of medicines, such as semaglutide and tirzepatide. The FDA doesn't test these medicines for how well they work or how safe they are.

The FDA urges people to get a prescription from their healthcare professionals and have the prescription filled at a state-licensed pharmacy.
