On June 17, 2026, federal regulators opened a public comment period on how pharmacy benefit managers, or PBMs, are paid for the drugs they help manage, including GLP-1 medications. This is not a new rule yet, but the information gathered here could shape pricing changes that reach patients by 2028. If you take a GLP-1 medication or expect to need one in the coming years, this comment period is one of the few chances to have a direct say in how those costs get set.
The Request for Information asks PBM compensation and data collection questions that go to the heart of why drug prices at the pharmacy counter often do not match the list price set by manufacturers. PBMs negotiate rebates and fees between drug makers, insurers, and pharmacies, and those arrangements are largely hidden from the people actually paying for the medication. By collecting public input now, the government is building a record it can use to justify future rules on PBM transparency or compensation limits. If those rules follow the timeline suggested in the RFI, changes to what patients pay could begin taking effect in 2028. That is still two years away, but the comment period itself is open now, and the record being built during this window may determine how far any future rule reaches.
If you want a lower price at the pharmacy counter to become more than a hope, submitting a comment during this RFI period is a concrete way to make your experience part of the official record regulators are building. You do not need special expertise to do this. You can describe what you have paid out of pocket for a GLP-1 medication, how PBM practices have affected your access, or questions you have about how these fees are set. I would suggest checking the RFI's comment deadline soon, since these windows close quickly and this is one of the few points in the process where public input is directly invited before any rule is finalized.

A federal RFI on PBM compensation could lower your drug costs starting in 2028.
