A member asked:

Quasym lp is a brand name of methylphenidate sold in france. i did not respond to ritalin or concerta. is this likely to help ?

A doctor has provided 1 answer

Same drug: Ritalin (methylphenidate) and Concerta are brand names of two methylphenadate based products. The Concerta is a timed released delivery system that has some advantages over the short acting products, but you are dealing withe same med.
