The most common side effects of Lipitor, as reported by Mayo Clinic [2], include muscle pain and damage, liver damage, digestive problems, and an increased risk of developing type 2 diabetes. In rare cases, the medication can also cause memory loss, confusion, and other cognitive problems. Patients who experience any of these side effects should consult their doctor immediately.

A study published in the National Center for Biotechnology Information [3] found that while Lipitor is generally safe and effective, it can cause a variety of side effects, including muscle pain, liver damage, and gastrointestinal problems. The study also found that patients taking Lipitor had a slightly increased risk of developing diabetes.

In conclusion, Lipitor is a medication used to lower cholesterol levels, but it can cause several side effects.
