Lipitor, also known as atorvastatin, is a medication primarily used to lower cholesterol levels and reduce the risk of heart-related conditions. While the sources provided do not specifically mention appetite changes as a common side effect of Lipitor, it is important to note that individual responses to medications can vary. Some potential side effects of Lipitor listed by the Mayo Clinic include muscle pain, weakness, and stomach pain, but changes in appetite are not specifically mentioned [2]. Healthline also outlines side effects of Lipitor, which include muscle aches, joint pain, and diarrhea, but does not specifically mention appetite changes [3].

It is advisable to consult with a healthcare provider or pharmacist if you experience any unusual or bothersome side effects while taking Lipitor. They can provide personalized advice and guidance based on your individual health profile and medication regimen.
