It is most certainly the same thing. The main ingrediant is Methylphenidate. From add.about.com/od/concerta/s, "Methylphenidate is the main ingredient in Ritalin, Concerta and Medadate. Find out side effects, drug interactions and precautions before you start taking this medication."
Commonly Used Names

Ritalin
Ritalin SR
PMS-Methylphenidate
Riphenidate
Concerta (Extended release)
Metadate

I hate to get personal with you here but if you did not even know that then you need to question every thing you think you know about this subject.

Thanks for noting that Ritalin by any other name is still ritalin. Didn't read all the 300+ posts but thought I would note that one of the "irreversible" side effects of prolonged Ritalin use is shrinkage of the cerebral cortex. Not a good thing.

I don't need to question anything...but thanks...Concerta worked..Ritalin didn't..so....

Regardless my son no longer takes either...

And I will again say these medications are needed in some circumstances..every parent needs to be educated and make a correct decision.
