Lipitor is a brand name for the drug atorvastatin, which is a medication used to lower cholesterol levels and reduce the risk of heart disease [1]. According to the FDA label, Lipitor is approved for use in adults and children who are at least 10 years old [3]. The recommended starting dose for most adults is 10 mg once daily, and the maximum dose is 80 mg once daily [3]. However, the dose may be adjusted based on individual patient needs and medical history [3].

A study published in the Journal of Clinical Lipidology found that atorvastatin was safe and effective in reducing cholesterol levels in children and adolescents with familial hypercholesterolemia, a genetic disorder that causes high cholesterol levels [2]. The study included participants as young as 6 years old and found that atorvastatin was well-tolerated and effective in reducing LDL cholesterol levels [2].

In summary, Lipitor (atorvastatin) is approved for use in adults and children who are at least 10 years old, and may be prescribed to children as young as 6 years old for certain medical conditions [1][2][3]. However, the appropriate dose and duration of treatment should be determined by a healthcare provider based on individual patient needs and medical history.
