Statins are on the whole very well tolerated by the vast majority of people taking them.
I have never heard of anyone becoming acutely incapacitated by taking it.
Liver and muscle issues are well documented, not common and reversible (there was one statin that could give a nasty reaction to your muscles in extremis fatal but that one is withdrawn - can not remember the name now)
The benefits they have in both primary and secondary prevention are beyond dispute.
