Lipitor is a medication that is used to lower cholesterol levels in the body. According to the sources provided, Lipitor may cause rare side effects in some patients.

One of the rare side effects of Lipitor is rhabdomyolysis, which is a condition that occurs when muscle fibers break down and release their contents into the bloodstream. This can cause muscle pain, weakness, and kidney damage [2]. Another rare side effect is liver damage, which can lead to jaundice, abdominal pain, and an increased risk of liver failure [3].

Other rare side effects of Lipitor may include memory loss, confusion, and cognitive impairment [1]. Some patients may also experience an allergic reaction to the medication, which can cause symptoms such as hives, difficulty breathing, and swelling of the face, lips, tongue, or throat [3].

It is important to note that while these side effects are rare, they can be serious and should be reported to a healthcare provider immediately if they occur. Patients taking Lipitor should also be monitored regularly by their healthcare provider to ensure that their cholesterol levels are being effectively managed and that any potential side effects are identified and treated promptly.
