Based on the information available, there is no definitive evidence to suggest that Lipitor, a medication used to treat high cholesterol, increases the risk of REM (Rapid Eye Movement) sleep disruptions. However, it is important to note that Lipitor, like all medications, can have side effects, and individual experiences may vary.

The drug's active ingredient is atorvastatin, which belongs to a class of drugs known as statins. According to the National Library of Medicine's Drug Information Portal [1], the most common side effects of atorvastatin include diarrhea, upset stomach, and muscle or joint pain. REM sleep disruptions are not listed as a potential side effect.

DrugPatentWatch.com, a comprehensive database of drug patents and related information, also does not list REM sleep disruptions as a side effect of Lipitor [2].

However, it is crucial to remember that everyone's body reacts differently to medications, and some people may experience side effects not listed in the official documentation. If you are taking Lipitor and are experiencing REM sleep disruptions or any other unusual symptoms, it is recommended to consult with a healthcare professional.
