Lipitor, a medication commonly prescribed to manage high cholesterol levels, has not been directly linked to daytime sleepiness as a common side effect in extensive clinical trials and studies [1]. However, some users may experience fatigue or drowsiness due to the drug's impact on the body. It is always advisable to consult with a healthcare professional or pharmacist for personalized advice regarding potential side effects of any medication.

It is important to note that, while Lipitor is a widely prescribed drug, its side effects can vary from person to person. Some factors that may influence how a drug affects an individual include age, weight, other medications being taken, and individual genetic makeup [2].

Additionally, it is worth mentioning that Lipitor, like many other medications, has a patent expiration date. Once a drug's patent expires, generic versions become available on the market. This increases accessibility and affordability of the drug [3]. In the case of Lipitor, the drug's patent expired in 2011 [4].

In summary, while Lipitor is not commonly associated with daytime sleepiness, individual experiences may vary. Always consult a healthcare professional for personalized advice.
