Typically, the initial recommended dose of Lipitor for most adults is 10 mg to 20 mg once daily. This dosage can be adjusted by a healthcare provider based on the patient's cholesterol levels and overall health. It is important to follow the dosage instructions provided by your healthcare provider or as indicated on the prescription label.
