Based on the information available, there are no known direct sodium-related side effects associated with Lipitor (atorvastatin). Lipitor is a statin medication used to lower cholesterol levels and reduce the risk of heart disease [1].

Common side effects of Lipitor include headache, muscle and joint pain, constipation, nausea, and diarrhea [1]. However, these side effects are not related to sodium.

It is important to note that some medications may interact with Lipitor and cause side effects. For instance, taking Lipitor with certain medications that can increase the levels of Lipitor in the body may increase the risk of muscle damage (rhabdomyolysis) [1].

In any case, if you have concerns about potential side effects or interactions with Lipitor, it is recommended to consult with a healthcare professional or pharmacist [1].
