Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the body [1]. According to Medical News Today, some common side effects of Lipitor include muscle pain, weakness, and tenderness, as well as an increased risk of developing type 2 diabetes [2].

Regarding the effect of Lipitor on blood pressure medication, a study conducted by Pfizer found that adding Lipitor to an effective blood pressure treatment provided a significant reduction in heart attacks or deaths from heart attacks over five years [3]. This suggests that Lipitor can be used in conjunction with blood pressure medication to improve cardiovascular health.

However, it is important to note that Lipitor may interact with certain blood pressure medications, such as amlodipine and diltiazem, potentially leading to increased side effects [1]. Therefore, it is crucial to consult with a healthcare provider before taking Lipitor in combination with any blood pressure medication.

In conclusion, Lipitor can be used alongside blood pressure medication to improve cardiovascular health. However, it is important to be aware of potential interactions and to consult with a healthcare provider before taking Lipitor in combination with any blood pressure medication.
