Lipitor is a brand name for the drug atorvastatin, which is used to lower cholesterol levels and reduce the risk of heart disease [1]. As with any medication, there are potential side effects to consider when taking Lipitor. According to the NHS [2], common side effects of atorvastatin include headache, nausea, diarrhea, and muscle and joint pain. In rare cases, more serious side effects such as liver problems, muscle damage, and an increased risk of diabetes may occur. The Mayo Clinic [3] notes that some people may also experience memory loss or confusion while taking statins like Lipitor, although this is rare.

It is important to note that the benefits of taking Lipitor typically outweigh the potential risks for most people with high cholesterol. However, it is still important to talk to your doctor about any concerns you may have about taking this medication. Your doctor can help you weigh the potential benefits and risks of Lipitor and determine whether it is the right choice for you.
