A major review finds most statin side-effects listed on labels are not caused by the drugs.
Researchers published the analysis in The Lancet after reviewing 19 trials involving 124,000 people.
Evidence supported muscle pain, diabetes risk, and four minor effects, including liver test changes and swelling.
Researchers found no strong evidence for 62 other listed effects, including memory loss and sleep problems.
Christina Reith said statins did not increase common complaints compared with placebo.
Experts said benefits clearly outweighed risks and called for updated drug labels.
