Lipitor (atorvastatin) is a medication used to lower cholesterol levels in the body [2]. According to the sources provided, weight loss does not appear to affect Lipitor dosage. However, it is important to note that Lipitor dosage is determined based on several factors, including age, gender, medical history, and current health status [2][3].

The dosage of Lipitor is typically prescribed by a doctor and is based on the patient's cholesterol levels. The recommended starting dose for most adults is 10-20 mg per day, which can be increased to a maximum of 80 mg per day if necessary [2].

While weight loss is not a direct factor in determining Lipitor dosage, it can indirectly affect cholesterol levels. Losing weight can help lower LDL (bad) cholesterol levels and increase HDL (good) cholesterol levels, which may result in a lower dosage requirement for Lipitor [1][3].

It is important to note that weight loss should not be used as a substitute for Lipitor or any other cholesterol-lowering medication. It is always recommended to consult with a healthcare professional before making any changes to medication dosage or treatment plans [3].
