Based on the information available, there is no evidence to suggest that Lipitor (atorvastatin) directly causes drowsiness immediately after taking it [1]. Lipitor is a statin medication used to treat high cholesterol levels and prevent cardiovascular disease [1].

Common side effects of Lipitor include diarrhea, upset stomach, and muscle or joint pain [1]. Drowsiness is not listed as a common side effect of Lipitor [1]. However, it is important to note that everyone's reaction to medication can vary, and some people may experience unexpected side effects [2].

If you experience drowsiness or any other unexpected symptoms after taking Lipitor, it is recommended to consult with a healthcare professional [2]. They can help determine if the medication is the cause of the symptoms or if there may be another underlying issue [2].

In summary, while Lipitor is not known to cause drowsiness immediately after taking it, individual reactions to medication can vary. If you experience drowsiness or any other unexpected symptoms after taking Lipitor, it is recommended to consult with a healthcare professional.
