Lipitor, also known as atorvastatin, is a prescription medication used to lower cholesterol levels and reduce the risk of heart disease. According to Drug Patent Watch [1], Lipitor is safe for those with high blood pressure as it does not directly affect blood pressure. However, it is important to note that some of the side effects of Lipitor, as listed by Medical News Today [2], can include headaches, muscle pain, and weakness, which could potentially exacerbate high blood pressure symptoms.

That being said, a study conducted by Pfizer [3] 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. This suggests that Lipitor may be a beneficial addition to high blood pressure treatment for those at risk for heart disease.

As with any medication, it is important to consult with a healthcare provider to determine if Lipitor is safe and appropriate for an individual's specific health needs and medical history.
