Lipitor (atorvastatin) is a prescription medication used to lower cholesterol levels in the blood. The dosage of Lipitor can vary depending on the individual's cholesterol levels, age, and medical history. The recommended starting dose for most adults is 10 to 20 mg once daily, which can be increased up to 80 mg per day if necessary [2]. However, it is important to consult with a healthcare provider before changing the dosage of Lipitor.

According to Drug Patent Watch [1], Lipitor is available in several strengths, including 10 mg, 20 mg, 40 mg, and 80 mg tablets. The website provides information on the patent status of Lipitor and its generic equivalents, but it does not provide information on dosages.

Healthline [2] notes that the dosage of Lipitor should be individualized based on the patient's cholesterol levels and medical history. The website also recommends starting with a lower dose and gradually increasing the dose as needed. Patients should not exceed a maximum daily dose of 80 mg.

Medscape [3] provides detailed information on the dosing of Lipitor for various patient populations, including adults, children, and patients with renal or hepatic impairment. The website notes that the recommended starting dose for most adults is 10 to 20 mg once daily, and the maximum daily dose is 80 mg. Patients with renal impairment may require lower doses, while patients with hepatic impairment may require careful monitoring and dose adjustments.

In conclusion, the recommended dosage of Lipitor can vary depending on the individual's cholesterol levels, age, and medical history. The starting dose is typically 10 to 20 mg once daily, and the maximum daily dose is 80 mg. However, it is important to consult with a healthcare provider before changing the dosage of Lipitor.
