Lipitor is a brand name for the drug atorvastatin, which is a type of statin medication used to lower cholesterol levels in the blood [1]. Statins like Lipitor can be prescribed to individuals who have high blood pressure, as high blood pressure is a risk factor for heart disease, and statins can help reduce the risk of heart disease [2]. However, it is important to note that statins do not directly lower blood pressure [3].

Regarding how often blood pressure should be checked while taking Lipitor, the sources provided do not give a specific answer. However, it is generally recommended that individuals with high blood pressure have their blood pressure checked regularly, even if they are taking medication to control it [2]. The American Heart Association recommends that individuals with high blood pressure check their blood pressure at least once a year, and more frequently if their blood pressure is not well controlled or if they have other risk factors for heart disease [4].

In summary, while Lipitor is a medication used to lower cholesterol levels and can be prescribed to individuals with high blood pressure, it does not directly lower blood pressure. It is important for individuals with high blood pressure to have their blood pressure checked regularly, even if they are taking medication to control it. The American Heart Association recommends checking blood pressure at least once a year, and more frequently if necessary [2][4].
