Biphentin is a long acting methylphenidate approved in Canada. It is similar to metadate at ritalin LA. Everyone responds differently to these meds, even to the different formulations of the same active ingredient.

Hi, we have started my son on 10mg of Biphentin - a new drug to help ADD. In just a few days we have seen some positive signs. There have been side effects but at this point minimal. I am wondering if anyone else has tried it and how it was working for them or their children.
