Lipitor is a brand name for the drug atorvastatin, which is a medication used to lower cholesterol levels and reduce the risk of heart disease and stroke [1]. According to Medical News Today, Lipitor can cause side effects such as muscle pain, weakness, and tenderness, and in rare cases, it can cause liver problems, kidney failure, and a severe allergic reaction [2].

However, the sources provided do not suggest that Lipitor can reduce blood pressure medication side effects. In fact, the Pfizer press release cited suggests that adding Lipitor to effective blood pressure treatment can reduce the risk of heart attacks or deaths from heart attacks over five years [3].

It is important to note that any changes to medication should be discussed with a healthcare provider. They can provide personalized recommendations based on individual health conditions and medication regimens.
