Lipitor (atorvastatin) is a medication used to lower cholesterol levels in the blood. The dosage of Lipitor varies depending on the patient's age, gender, and medical condition. According to the Mayo Clinic [2], the recommended starting dose for adults is usually 10 or 20 milligrams once a day, with the maximum dose being 80 milligrams per day. However, the appropriate dosage for each individual patient should be determined by their healthcare provider based on their specific needs and medical history.

It is important to follow the dosage instructions provided by your healthcare provider and to take Lipitor exactly as prescribed. Patients should not increase or decrease their dose of Lipitor without consulting their healthcare provider. According to Healthline [3], missing a dose of Lipitor should be taken as soon as possible, unless it is close to the time for the next dose, in which case the missed dose should be skipped.

Additionally, it is important to note that Lipitor is available in several different forms and strengths, including tablets and oral suspensions. The availability of different formulations and strengths may impact the dosage prescribed by a healthcare provider. According to Drug Patent Watch [1], Lipitor is available in strengths ranging from 10 to 80 milligrams, and the patent for the drug expired in 2011, making it available as a generic medication.

In summary, the appropriate dosage of Lipitor varies depending on the individual patient's needs and medical history, and should be determined by a healthcare provider. Patients should not adjust their dosage without consulting their healthcare provider, and should follow the dosage instructions provided. Lipitor is available in several different forms and strengths, and is available as a generic medication.
