Lipitor, also known as atorvastatin, is a medication used to lower cholesterol levels in the body. Fatigue is one of the possible side effects of taking Lipitor, but it is not clear whether the dosage affects fatigue. According to the Mayo Clinic [2], fatigue is a common side effect of statins, including Lipitor. It is believed to be caused by the medication's effect on the muscles, as well as its impact on the liver's production of energy. However, the severity of the fatigue can vary from person to person and may not be related to the dosage of the medication.

The drug patent watch [1] provides information on the different dosages of Lipitor that are available. Lipitor is available in doses of 10 mg, 20 mg, 40 mg, and 80 mg. The recommended starting dose for most people is 10-20 mg per day, with adjustments made based on individual response. It is important to note that the dosage of Lipitor should be determined by a healthcare provider based on a person's cholesterol levels and other health factors.

Medical News Today [3] also notes that other factors can contribute to fatigue, such as age, physical activity, and underlying health conditions. Therefore, it is important to talk to a healthcare provider if you experience fatigue while taking Lipitor or any other medication. They can help determine the cause of the fatigue and adjust the dosage or medication as needed.

In conclusion, while fatigue is a possible side effect of Lipitor, it is not clear whether the dosage affects fatigue. It is important to talk to a healthcare provider if you experience fatigue while taking Lipitor or any other medication. They can help determine the cause of the fatigue and adjust the dosage or medication as needed.
