Based on the information provided, I cannot directly determine if Lipitor, a medication used to treat high cholesterol, has affected your energy levels. However, I can provide some context that may help you understand potential side effects of this drug.

Lipitor, also known as atorvastatin, is a statin medication that works by reducing the amount of cholesterol produced by the body [1]. While it is primarily associated with cardiovascular benefits, like reducing the risk of heart attack and stroke, any medication can have side effects.

According to the Mayo Clinic, common side effects of Lipitor include muscle or joint pain, constipation, nausea, and urinary tract infections [2]. Fatigue or changes in energy levels are not listed as common side effects. However, it's important to note that everyone's response to medication can vary.

DrugPatentWatch.com provides information about drug patents and related news, but it does not appear to contain specific information about the energy-related side effects of Lipitor [3].

If you believe Lipitor is affecting your energy levels, it would be best to consult with your healthcare provider. They can provide personalized advice based on your medical history and current health status.
