Lipitor is not primarily used for blood pressure, but rather to lower cholesterol levels in the blood. However, a study conducted by Pfizer found that adding Lipitor early to effective blood pressure treatment provided a significant reduction in heart attacks or deaths from heart attacks over five years [2]. It is important to note that Lipitor is a prescription medication and should only be taken under the supervision of a healthcare provider. Additionally, like all medications, Lipitor has potential side effects such as muscle pain and weakness, liver damage, and an increased risk of diabetes [3]. As with any medication, the effectiveness of Lipitor may vary depending on individual circumstances and should be discussed with a healthcare provider [1].
