Lipitor, also known as atorvastatin, is a medication primarily used to lower cholesterol levels in the blood. While it is not commonly associated with directly impacting appetite, some individuals may experience side effects that could potentially affect their appetite. The most common side effects of Lipitor include muscle aches or weakness, nausea, diarrhea, and constipation, but changes in appetite are not frequently reported. However, as with any medication, individual responses can vary, and some people may experience appetite changes as a side effect. If you notice any unusual changes in your appetite while taking Lipitor, it is advisable to consult with your healthcare provider for further guidance.
