Questions
Why use Open Payments as a signal?
It is the only public, business-level record of which practices have a relationship with the GLP-1 manufacturers. It is published by CMS under the Sunshine Act. We export the practice address only, never the recipient's name or the dollar amounts.
Compounded semaglutide: is it legal?
Compounding is allowed only while the FDA lists a shortage or for a documented patient-specific need, and only from a pharmacy licensed in your state (503A) or registered with the FDA (503B). Rules differ by state; our pharmacy layer asserts licensure only, never the legality of a particular prescription. A vial from a website with no pharmacy license is not a pharmacy product.
Wayfinding, not a referral and not an endorsement. A business here has not been reviewed by us unless it also appears in the provider directory. Spot an error or a closure? Report it from the lookup. How this page is built: methodology.
