Lipitor, a medication commonly used to treat high cholesterol, does not directly affect low sodium levels in the human body. Lipitor, also known as atorvastatin, is a type of statin that works by blocking a substance your body needs to make cholesterol [1].

Cholesterol is a fatty substance known as a lipid, and it's an essential component of all cells. However, high levels of cholesterol can lead to health problems, such as heart disease and stroke. Lipitor helps to lower these harmful levels of cholesterol in the blood [1].

Sodium, on the other hand, is an essential electrolyte that helps regulate fluid balance, nerve function, and muscle contractions. Low sodium levels, or hyponatremia, can be caused by various factors, such as certain medications, kidney or liver diseases, heart failure, and dehydration [2].

There is no evidence or indication in the available information that Lipitor directly affects sodium levels in the human body [1]. However, it is always advisable to consult with a healthcare provider or pharmacist for personalized advice regarding medications and their potential interactions or side effects [3].
