After conducting a thorough investigation, there is no definitive evidence to suggest that Lipitor, a medication commonly used to treat high cholesterol, causes daytime sleepiness in a significant number of patients.

Lipitor, also known as atorvastatin, is a statin medication that works by reducing the amount of cholesterol produced by the body [1]. While Lipitor is known to have several side effects, including headache, nausea, and muscle pain, daytime sleepiness is not listed as a common side effect in the drug's prescribing information [2].

Moreover, a comprehensive review of the medical literature did not reveal any studies or reports indicating that Lipitor is associated with daytime sleepiness in a significant number of patients [3][4].

It is important to note that medications can affect people differently, and some individuals may experience daytime sleepiness or other side effects while taking Lipitor. If a patient experiences daytime sleepiness or any other unusual symptoms while taking Lipitor, they should consult with their healthcare provider [2].

In conclusion, while Lipitor can cause several side effects, there is no evidence to suggest that it causes daytime sleepiness in many patients. Patients who experience daytime sleepiness or any other unusual symptoms while taking Lipitor should consult with their healthcare provider.
