Finally, RARE SIDE EFFECTS (may affect up to 1 in 1,000 patients) are:

Do note that the above list is not exclusive. Be sure to inform your doctor or healthcare provider of any side effects you experience from your use of statins.

Now, if you think the above potential side effects are easy-peasy, the Food and Drug Administration (FDA) has a patient advisory on very serious but rare statins side effects. According to the agency, patients taking in statins should be aware of the following:



  • There have been rare reports of serious liver problems in patients taking statins. Patients should notify their healthcare professional right away if they have the following symptoms: unusual fatigue or weakness; loss of appetite; upper belly pain; dark-colored urine; or yellowing of the skin or the whites of the eyes.
  • Memory loss and confusion have been reported with statin use. These reported events were generally not serious and went away once the drug was no longer being taken.
  • Increases in blood sugar levels have been reported with statin use.
  • Potential for muscle damage. Some drugs interact with statins in a way that increases the risk of muscle injury called myopathy, characterized by unexplained muscle weakness or pain. For this reason, the FDA is revising the drug label for Lovastatin to clarify the risk of myopathy. The label will reflect what drugs should not be taken at the same time, and the maximum lovastatin dose if it is not possible to avoid use of those other drugs.

Note: Statins include atorvastatin (Lipitor), fluvastatin (Lescol), lovastatin (Altoprev), pitavastatin (Livalo), pravastatin (Pravachol), rosuvastatin (Crestor) and simvastatin (Zocor).
