Lipitor is a brand name for atorvastatin, which is a medication used to lower cholesterol levels and reduce the risk of heart attack and stroke. According to [2], some common side effects of Lipitor include headache, muscle pain, weakness, and stomach pain. Rare side effects include liver problems, allergic reactions, and an increased risk of diabetes. Lipitor may also interact with other medications, so it is important to inform your doctor of all medications you are taking.

However, [3] reports that adding Lipitor early to effective blood pressure treatment provided a significant reduction in heart attacks or deaths from heart attacks over five years. The study found that adding Lipitor to blood pressure treatment reduced the risk of heart attack by 25% and the risk of death from heart attack by 48%.

In conclusion, while Lipitor may have some side effects, it can also be effective in reducing the risk of heart attack and stroke when added to blood pressure treatment. It is important to discuss any concerns or potential side effects with your doctor.
