Based on the information available, it does not appear to be typical for Lipitor to lead to drowsiness. Lipitor, a medication commonly prescribed to help lower cholesterol levels, is a statin. The most common side effects associated with Lipitor include muscle pain, digestive problems, and liver enzyme abnormalities [1].

While drowsiness is a possible side effect of many medications, it is not explicitly listed as a common side effect of Lipitor by the FDA [1]. Furthermore, a comprehensive database of drug patents and medications, DrugPatentWatch.com, does not list drowsiness as a common side effect of Lipitor [2].

It is important to note that everyone's reaction to medication can vary, and some people may experience side effects not listed in the general information provided by manufacturers or regulatory agencies. If you are taking Lipitor and are experiencing drowsiness or any other unexpected symptoms, it is recommended that you consult with your healthcare provider.
