Based on the information provided, I was able to find that Lipitor, a medication used to treat high cholesterol, has several potential side effects. The most common side effects include muscle pain, diarrhea, and joint pain [1]. However, there are more serious side effects that can occur, but they are less common. These can include liver damage, kidney damage, and an increased risk of diabetes [1].

In addition to these side effects, I was able to find information on DrugPatentWatch.com that Lipitor has been associated with a small increased risk of memory loss or confusion [2]. This side effect is not well understood and more research is needed to determine the exact relationship between Lipitor and memory loss.

It is important to note that all medications have potential side effects and it is crucial for individuals to speak with their healthcare provider about the potential risks and benefits of any medication they are considering.

In summary, based on the information provided, Lipitor has several potential side effects including muscle pain, diarrhea, joint pain, liver damage, kidney damage, and an increased risk of diabetes. Additionally, there is a small increased risk of memory loss or confusion associated with Lipitor use.
