That’s usually the way with generics.

One reason is that the standards allow for a variance of +10% to -10% of the strength of the branded version.  That’s a range of 20%.

And it can make a huge difference if you’re used to a generic version that’s 10% weaker than the branded, and then you’re suddenly switched to a different generic version that happens to be 10% stronger than the branded.  It may suddenly be too high a dose for you.

Or, if you’re used to the stronger generic, and are suddenly switched to the weaker one, you’ll wonder why your meds suddenly aren’t working so well.

The situation gets even trickier in the case of Concerta, because it’s the unique osmotic delivery system that makes it Concerta.  This delivery system is patented, which means that none of the generics have it.  Therefore, they are NOT a generic equivalent for Concerta, despite the manufacturers’ claims.  Health Canada is now studying this, and (hopefully) will come up with a ruling soon.
