Parent comment states active ingredients are the same, but the "non-active" ingredients can be different. So there is the possibility that something is different in the generic that could cause a reaction. I've had to use transdermal medication (patches) before, and one of the inactive ingredients that changes is the adhesive, I've noticed that the "brand name" version didn't cause skin breakouts, and the generic did.
