    I would direct you all to the ongoing issues going on with substitutions and unfortunately according to Wikipedia’s account of the Amneal company, from my comprehension, was founded on the basis of two things: 1) Impax, another generic, non-Janssen, manufacturer I believe of methylphenidate, in 2017 merged all its holdings with the Amneal company. 2) Amneal apparently did a large purchase of 5 of Mylan’s generics, and according to that forum, was one of the major root manufacturers that exhibited poor efficacy compared to Concerta.

    And the only sure-fire way, barring insurance limitations on what is allowed to be dispensed in the case of brand vs. generic, to guarantee that you will receive the brand form versus the generic is the prescriber has to physically write, NOT CHECK, “BRAND MEDICALLY NECESSARY” on the Rx.

    Hi, I have two quick questions for those of you who are dealing with low efficacy on Methylphenidate ER.

    1) One of you mentioned that while the FDA requires all SNDA’s for generics exhibit bioequivalence but not ensure delayed release delivery. Do you have a resource where I could research that stipulation in the FDA guidelines?

    2) I’m a long-time and long-term Concerta user. I’m unfortunately unable to recollect my previous generic, but just recently Walgreens started to supply a generic under the manufacturer Amneal starting in October. Has anyone used this form and seen less efficacy?
