Lipitor (atorvastatin) is a medication used to lower cholesterol levels in the blood. The recommended dosage of Lipitor depends on several factors, including the patient's age, medical condition, and other medications they may be taking.

According to Drugs.com [2], the recommended starting dose of Lipitor is usually 10-20 mg once daily, taken at any time of the day, with or without food. The dosage may be increased after two to four weeks of treatment, based on the patient's response to the medication. The maximum recommended daily dose of Lipitor is 80 mg.

Medscape [3] provides a similar recommendation, stating that the usual starting dose of Lipitor is 10-20 mg once daily, with a maximum dose of 80 mg once daily. They also note that the dosage may be adjusted based on the patient's response to the medication and their risk of developing cardiovascular disease.

DrugPatentWatch [1] provides information on the different strengths of Lipitor that are available, ranging from 10 mg to 80 mg. However, they do not provide specific dosage recommendations.

It is important to note that the recommended dosage of Lipitor may vary depending on the individual patient's medical history, current medications, and other factors. Patients should always consult with their healthcare provider to determine the appropriate dosage for their specific situation.
