Generic meds vs. label meds? ( serious inquiry )

[Zereh]

They're not "exactly" the same though they are often interchangeable. Pretty sure there is an 20% +/- variance allowed between a brand-named drug and their generic counterpart.

Generics work for some people, not for others. The same person can take generic meds of one kind but must have name-brand meds of another kind. Every person is unique and every case different.
