In a large prospective cohort study, statins were investigated in order to find any adverse or unintended effects.
Statins are said to lower the risk for adverse cardiovascular events. Of the two million study participants out of the UK, about 225,00 were new statin users. Each participant received one of five different statins: fluvastatin (Lescol ®), pravastatin (Mevacor ®), rosuvastatin (Crestor ®), simvastatin (Zocor ®), or atorvastatin (Lipitor ®).
Statin use was associated with a heightened risk of liver dysfunction, acute kidney failure, myopathy, and cataracts.
These adverse effects were true for each statin prescribed, and risk returned to normal after treatment.
