Taking statins doesn’t seem to actually cause memory problems, cancer, cataracts, nerve pain, erectile issues, or tendon problems, based on what we’ve seen so far.

What we've found so far is that taking statins does not appear to cause cognitive dysfunction, cancer, cataracts, peripheral neuropathy, erectile dysfunction, or tendonitis [1]. Our analysis of the available evidence currently includes one assertion, and it does not support the idea that statins lead to these side effects. We reviewed one claim based on existing research, and it indicates no clear link between statin use and the health issues listed in the question [1]. This means that, based on what we’ve seen so far, concerns about statins causing memory problems, cancer, cataracts, nerve pain, sexual dysfunction, or tendon inflammation are not backed by the evidence we’ve analyzed. However, our current analysis is limited to just one assertion, so our understanding is still early and could change as more data becomes available. We don’t yet have enough studies to say anything with confidence. The evidence we’ve reviewed leans toward no association, but that doesn’t rule out the possibility of rare or long-term effects. We also can’t say whether certain people might be more sensitive than others. Since we only have one data point so far, our view is incomplete. It’s important to remember that our analysis is ongoing. As we review more studies, our understanding may shift. Right now, we’re working with a very narrow base of evidence. Practical takeaway: Based on the one claim we’ve analyzed, there’s no sign that statins cause these side effects — but we need more evidence before we can say how strong that conclusion really is.
