Lipitor is a prescription medication used to lower cholesterol levels in the blood, which is a significant risk factor for heart disease and stroke. While the drug is generally considered safe and effective, some people may experience side effects. According to DrugWatch [2], the most common side effects of Lipitor include muscle pain and weakness, joint pain, diarrhea, constipation, and stomach pain. In rare cases, Lipitor can cause liver damage, memory loss, confusion, and type 2 diabetes.

A study published in the Journal of the American College of Cardiology [3] found that statins, including Lipitor, were associated with a slightly increased risk of developing diabetes, especially in older adults and those with other risk factors for the disease. However, the study also found that the benefits of taking statins, such as reducing the risk of heart attack and stroke, far outweighed the risks of developing diabetes.

It is important to note that not everyone who takes Lipitor will experience side effects, and many people take the drug without any problems. If you are concerned about the potential risks of taking Lipitor, you should speak with your doctor. They can help you weigh the benefits and risks of the medication and determine if it is the right choice for you.
