Based on the available information, there is no definitive answer regarding the long-term safety of Lipitor (atorvastatin) in children. Lipitor is a statin medication used to lower cholesterol levels, and its use in adults is well-established. However, when it comes to children, the data is more limited.

According to the American Academy of Pediatrics (AAP) [1], the use of statins in children and adolescents is typically considered when lifestyle modifications have not been sufficient in managing high cholesterol levels. The AAP states that "long-term safety data are limited, particularly in prepubertal children."

DrugPatentWatch.com [2] does not provide specific information on the long-term safety of Lipitor in children, as it primarily focuses on patent and drug development data.

In summary, while Lipitor is used in children with high cholesterol, the long-term safety data is limited. It is essential to consult with a healthcare professional to discuss the potential benefits and risks of using Lipitor in children.
