Lipitor is a medication used to lower cholesterol levels in the body, particularly LDL cholesterol. The recommended dosage of Lipitor for LDL reduction varies depending on the individual's condition and response to treatment. According to Drugs.com [2], the recommended starting dose of Lipitor is 10-20 mg once daily, which can be increased to a maximum of 80 mg once daily. Healthline [3] suggests that the typical starting dose is 10-20 mg per day, and the maximum dose is 80 mg per day. However, the dosage may be adjusted by a healthcare provider based on factors such as age, gender, liver function, and other medications being taken. Additionally, Drug Patent Watch [1] provides information on the different strengths of Lipitor available, ranging from 10mg to 80mg, which can be prescribed based on the patient's needs. It is important to note that Lipitor should be taken as directed by a healthcare provider and should not be adjusted without consulting them first.
