This website is dedicated to information specific to the Maximum Fair Price (MFP) for JANUVIA only.

JANUVIA is subject to the MFP under the Inflation Reduction Act beginning January 1, 2026. All valid, non-expired, saleable US NDCs of JANUVIA are included.

To streamline communication regarding MFP matters, Merck is using the Beacon platform which is available through Merck’s vendor, Second Sight Solutions. The Beacon platform is a free web-based application available to all dispensing entities. Merck encourages all dispensing entities to enroll in the Beacon platform. Beacon serves as the centralized hub for Merck to share key information with dispensing entities, including Merck’s MFP effectuation plan and its associated procedures. The Beacon platform also features a resolution center designed to facilitate the receipt, response, and tracking of communications from dispensing entities regarding MFP effectuation. Dispensing entities may contact the Beacon customer support center with specific questions about the Beacon platform and may view recorded webinars that explain Beacon platform functionality and use. Following a brief registration process, dispensing entities will be verified and then have access to Beacon. The Beacon platform is available online or via email 24 hours a day, 7 days a week, with live phone and chat support available from the Vendor’s representatives Monday through Friday, 9 AM to 9 PM ET. Dispensing entities may now register at Beacon.

Dispensing entities that are not 340B covered entities may also communicate with Merck regarding MFP-related matters for JANUVIA including if the dispensing entity believes a specific MFP refund transaction does not reflect appropriate access to the MFP for JANUVIA by completing the form below.
