Lipitor is a brand name for the medication atorvastatin, which is a type of statin used to lower cholesterol levels in the blood [1]. According to the Mayo Clinic, some of the most common side effects of atorvastatin include diarrhea, joint pain, and muscle pain [3]. However, none of the sources provided mention cravings as a side effect of atorvastatin.

The Drug Patent Watch website provides information on the patent status of Lipitor and its generic equivalents, but it does not offer any information on the medication's side effects or interactions [1].

A study published in the US National Library of Medicine National Institutes of Health examined the effects of atorvastatin on appetite and food intake in rats. The study found that atorvastatin did not have any significant effect on food intake or body weight, suggesting that the medication does not cause cravings or increased appetite [2].

In conclusion, while atorvastatin (Lipitor) may cause some side effects such as joint pain and muscle pain, there is no evidence to suggest that it causes cravings. If you are experiencing any unusual symptoms while taking atorvastatin, it is important to speak with your healthcare provider [3].
