Doctors are being warned to think more carefully about prescribing cholesterol-lowering drugs by researchers who have found a wide range of "unintended" side effects.
Some doses and types of statins are linked with effects that include liver problems and kidney failure.
BBC News reports:
"Researchers looked at data from more than two million 30-84 year-olds from GP practices in England and Wales over a six-year period. Adverse effects identified in the study, published in the British Medical Journal, include liver problems, acute kidney failure, muscle weakness and cataracts."
