Our anecdote: My fiancee was prescribed generic Exemestane. We 100% believed that “generic is exactly the same compound, just cheaper”. Her joints became stiff and sore. All over. It was debilitating. (It’s a known side-effect of the drug.) Took the generic for two years. Then the supply of generics ran out locally and we had to get brand-name Aromasin. The exact same compound. We had no expectations of different effects or less side effects. Her joint pain mostly cleared up. By like 90%. The difference - once it dawned on us - was shocking.
