Here is a recent article in the BMJ detailing the absence of numerous adverse effects of the statin class of drugs and the occurrence on a few beneficial effects. The article mentions cataract as a complication of statin therpay , an adverse effect that was of concern in very early animal work by Merck but about which I had stopped worrying until the BMJ article. In fact, there was this study from 2010 which claimed the opposite, i.e . a decrease in the risk of cataracts from statin use and this 2003 fairly large case-control article that found no effect in regard to cataract.
For a while those who read or skimmed medical literature were treated to an array of articles that claimed numerous effects of the statins that were not just further evidence of the pleotrophic effects of statins but were really just short of miraculous. I wrote about some of those claims here. Most of those claims did not pan out. Another claim,that of the statins causing an epidemic of heart failure made by Dr. Peter Langsjoen ( see here),does not appear verified by the BMJ article.
