*The number of formularies counts the unique formularies that offer this medication. As a note, the same formulary can be used by one or many different Medicare Part D plans. The same formulary can be used by both PDP and MAPD plans.

What Could the Addition of New Generic Drugs Mean to You?

  • You may be able to save money by switching from the brand-name drug to its generic equivalent – with your prescriber’s approval and a new prescription. Please note, you will need to look carefully at coverage costs as we have found that many generics are being offered on the same tier as their brand-name equivalent or the generics do not have a significantly lower retail price.

  • Your brand-name drug may no longer be available if a generic is now available. Based on past experience, you may find that many Medicare Part D plans discontinue coverage for the brand-name drug in the months following the introduction of the generic equivalent - or your plan may immediately drop the brand-name drug now that the generic is being introduced.

    If you have received notice from your Medicare Part D plan that your brand-name medication will be dropped, you should speak with your prescriber to determine if you can take the generic equivalent or if you must continue taking the brand-name drug, you will need to ask your plan for a formulary exception to continue coverage for your brand-name drug.

    You can click for a chart showing the trends in formulary coverage for some of the more popular Medicare drugs and their generic equivalents.
As a note, both our Formulary Browser (you can view all the drugs covered by a single Medicare prescription drug plan) and our Q1Rx Drug Finder (you can view all the Medicare drug plans covering a single drug) have been updated with the May 2024 Medicare Part D formulary data.
