Lipitor is a medication used to lower cholesterol levels in the blood and prevent heart disease [1]. It is not primarily used for treating high blood pressure, but it can be prescribed to people with high blood pressure who also have high cholesterol levels. While Lipitor is generally considered safe and effective, it can cause side effects in some people [2].

The most common side effects of Lipitor include headache, muscle pain, diarrhea, and nausea. Some people may also experience more serious side effects, such as liver problems, muscle damage, and an increased risk of diabetes [2]. Patients who experience any of these side effects should consult their doctor immediately.

In a study conducted by Pfizer, the makers of Lipitor, adding Lipitor to an effective blood pressure treatment provided a significant reduction in heart attacks or deaths from heart attacks over five years [3]. However, the study did not specifically address the potential side effects of Lipitor in people with high blood pressure.

In conclusion, Lipitor is generally considered safe and effective for lowering cholesterol levels in the blood and preventing heart disease. However, it can cause side effects in some people, including those with high blood pressure. Patients who experience any side effects should consult their doctor immediately.
