FDA warns against using generic weight loss drugs.

The FDA has warned consumers against using off-brand versions of popular weight-loss drugs Ozempic, Rybelsus, and Wegovy, as they may contain different ingredients from the brand-name drugs that are neither safe nor effective. Compounded versions of the drug's active ingredient, semaglutide, have been reported to cause problems. Compounded drugs are not FDA-approved, and the agency does not verify their safety or effectiveness. Some states have raised concerns about the safety of some of the compounded drugs, and states have tried to take action to curb their manufacturing.
