Lipitor is a brand name for atorvastatin, which is a medication that belongs to a class of drugs called statins. Statins are used to lower cholesterol levels in the body by inhibiting an enzyme that produces cholesterol in the liver. [1]

According to a report by ABC News, some people who take statins like Lipitor may experience fatigue or weakness as a side effect. The report cites a study published in the Archives of Internal Medicine, which found that nearly 40% of patients taking statins reported experiencing fatigue. However, the study did not establish a direct causal relationship between statins and fatigue. [2]

Healthline also reports that fatigue is a potential side effect of statins like Lipitor. The article notes that while not everyone experiences fatigue while taking statins, it is a common complaint. The article also suggests that people who experience fatigue while taking statins may benefit from adjusting the timing of their medication or switching to a different statin. [3]

In conclusion, while Lipitor and other statins are effective at lowering cholesterol levels, they may cause fatigue or weakness as a side effect. However, not everyone experiences this side effect, and it is not clear whether the fatigue is directly caused by the medication. If you are experiencing fatigue while taking Lipitor, you may want to talk to your doctor about adjusting your medication or trying a different statin.
