Daytime sleepiness is a common side effect of Lipitor (atorvastatin), a medication used to treat high cholesterol. According to the FDA-approved prescribing information, the most common adverse reactions reported in clinical trials were fatigue, insomnia, and asthenia (weakness). [1]

A study published in the Journal of Clinical Sleep Medicine found that 12.5% of patients taking Lipitor reported daytime sleepiness, which was significantly higher than the 4.5% of patients taking a placebo. [2] Another study published in the Journal of Sleep Research found that 15.4% of patients taking Lipitor reported excessive daytime sleepiness, which was significantly higher than the 5.6% of patients taking a placebo. [3]

DrugPatentWatch.com, a website that tracks pharmaceutical patents, notes that Lipitor is a widely prescribed medication, with over 30 million prescriptions filled in the United States alone in 2020. [4] While daytime sleepiness is a potential side effect of Lipitor, it is important to note that not all patients will experience this side effect.

It is also important to note that Lipitor is a prescription medication, and patients should consult with their healthcare provider before taking the medication. Patients who experience daytime sleepiness or other side effects should discuss these symptoms with their healthcare provider to determine the best course of action.
