Approval applies to the finished medicine

FDA explains that compounded drugs are not FDA approved. The agency does not review their safety, effectiveness, and quality before marketing. Compounding may be appropriate for a patient who cannot be treated with an approved medicine.

A pharmacy's ability to prepare a product does not make that preparation an approved generic. Ask whether the proposal is an approved finished product or a compounded preparation, and request a plain explanation of why that choice is being made.

GLP-1 products have specific concerns

FDA's GLP-1 safety page describes concerns with unapproved versions, including dosing errors and products using semaglutide salt forms different from the active ingredient in approved drugs. It recommends a prescription and a state-licensed pharmacy.

These issues make exact labeling and clear pharmacy instructions especially important. If information is unclear or inconsistent, contact the prescriber or pharmacist rather than converting units or copying instructions from another product.

Ask before making a commitment

Ask for the dispensing pharmacy's name, the exact product, the reason for compounding, and the route for reporting a concern. Ask which current rules the prescribing and pharmacy teams are relying on, since shortage and enforcement policies can change.

This article does not determine whether a particular preparation can legally be compounded or sold. It gives you questions to take to the professionals responsible for the prescription and dispensing decision.
