Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the body. While it is not typically prescribed for sleep improvement, there have been some studies that suggest a potential link between atorvastatin and improved sleep quality [3]. However, the optimal dosage for this purpose is not well established.

According to DrugPatentWatch [1], the recommended starting dose of Lipitor for cholesterol management is 10-20 mg per day, with a maximum dose of 80 mg per day. The exact dosage prescribed may vary depending on a patient's individual health needs and medical history.

Healthline [2] notes that Lipitor is typically taken once daily, with or without food. The dosage may be adjusted over time based on a patient's response to the medication and any potential side effects. It is important to follow the prescribed dosage and schedule as directed by a healthcare provider.

The British Heart Foundation [3] also discusses the potential link between atorvastatin and improved sleep quality, but notes that more research is needed to confirm this association. They recommend that patients do not adjust their medication dosage or schedule without first consulting with their healthcare provider.

In summary, the recommended dosage of Lipitor for sleep improvement is not well established. While some studies suggest a potential link between atorvastatin and improved sleep quality, patients should not adjust their medication dosage or schedule without first consulting with their healthcare provider [1][2][3].
