Lipitor is a commonly prescribed medication used to lower cholesterol levels in the blood. While it is generally well-tolerated, there are potential side effects associated with its use. According to the Mayo Clinic [2], the most common side effects of Lipitor include headache, muscle aches and pains, diarrhea, and constipation. These side effects are usually mild and go away on their own, but if they persist or become severe, patients should consult their doctor.

In rare cases, Lipitor can cause more serious side effects, such as liver damage, muscle damage, and an increased risk of developing type 2 diabetes. Patients who experience unexplained muscle pain, tenderness, or weakness, especially if accompanied by fever or fatigue, should seek medical attention immediately [2].

According to Medical News Today [3], Lipitor can also cause cognitive side effects such as memory loss, confusion, and forgetfulness, although these side effects are rare. It is important to note that the benefits of taking Lipitor typically outweigh the potential risks, especially for patients who have a high risk of heart disease or stroke [3].

It is essential to consult a doctor before taking Lipitor or any other medication to discuss potential side effects and determine if it is the right choice for you. Patients should also inform their doctor of any existing medical conditions and medications they are taking to avoid any adverse reactions [1].
