The main reason why statin drug side effects are considered rare is that doctors are hesitant to report any suspected statin drug side effects to the FDA because they have a hard time proving that a statin drug caused the side effects and they become overloaded with paperwork, etc. I asked my doctor if he had reported my problems to FDA and that was his reponse. Also, he said, he had reported a drug problem to the FDA quite awhile ago and does not want to do it again. That's the problem in a nutshell.
