Based on the information provided, I cannot determine whether a specific individual's use of Lipitor has affected their blood pressure. Lipitor, a medication commonly prescribed to lower cholesterol levels, is not known to have a direct impact on blood pressure [1]. However, it is possible for Lipitor to interact with other medications that may affect blood pressure [2].

It is always recommended to consult with a healthcare professional or pharmacist for personalized advice regarding medications and potential interactions. They can provide guidance based on an individual's medical history and current medications.
