While the Mallinckrodt generic and a couple others lost their generic equivalency status, they weren’t pulled from the market. The chains should not be using them but they are.
There is a true generic equivalent for Concerta, made by the brand company. It’s sold under Actavis. Walgreens uses this as their generic in my area — I thought it was a company-wide policy. You can always ask your pharmacist to stock a particular manufacturer for you. They more say no, but some will do it.
