Lipitor is a brand name for the drug atorvastatin, which is a medication used to lower cholesterol levels in the body. While the drug can be effective in treating high cholesterol, it may also have some side effects, including impacts on energy levels.

According to Drug Patent Watch [1], Lipitor is available in tablet form in doses of 10, 20, 40, and 80 mg. The dosage prescribed will depend on the patient's medical history, current health status, and other factors. The recommended starting dose for most adults is 10-20 mg per day.

A study published in the Journal of Clinical Lipidology [2] found that atorvastatin treatment did not significantly affect physical activity or energy levels in patients with high cholesterol. The study also found that there was no significant difference in energy levels between patients taking atorvastatin and those taking a placebo.

However, some patients may experience side effects while taking Lipitor, including fatigue and weakness [3]. These side effects may be more common at higher doses of the medication. Patients who experience these side effects should talk to their doctor about adjusting their dosage or switching to a different medication.

In conclusion, while Lipitor may have some impact on energy levels, the available evidence suggests that it is generally well-tolerated and does not significantly affect physical activity or energy levels in most patients. However, patients who experience side effects while taking the medication should talk to their doctor about adjusting their dosage or exploring alternative treatment options.
