Based on the information available, there is no definitive evidence that Lipitor, a medication commonly used to treat high cholesterol, lists mood swings as a side effect. The official Lipitor medication guide published by Pfizer, the drug's manufacturer, does not list mood swings as a potential side effect [1].

However, it is important to note that medications can affect individuals differently, and some people may experience side effects not listed in the official medication guide. If you are taking Lipitor and have noticed mood swings or other unusual symptoms, it is recommended that you consult with your healthcare provider [2].

It is also worth noting that Lipitor, like all prescription medications, is subject to patent protection and generic alternatives may not be available. According to DrugPatentWatch.com, Lipitor's patent expired in 2011, but Pfizer was able to extend its exclusivity through various patent extensions and settlements [3]. As a result, generic versions of Lipitor were not widely available until 2015 [3].

In summary, while Lipitor's official medication guide does not list mood swings as a potential side effect, it is always important to consult with a healthcare provider if you experience unusual symptoms while taking any medication. Additionally, it is worth noting that Lipitor's patent history may have affected the availability of generic alternatives.
