Lipitor is a brand name for atorvastatin, which is a medication used to lower cholesterol levels in the body [1]. According to a study published in the Journal of Clinical Lipidology, atorvastatin was found to be generally well-tolerated by patients, with the most common side effects being muscle pain and gastrointestinal symptoms [2]. However, the study did not mention fatigue as a side effect of atorvastatin.

Fatigue during morning workouts can be caused by a variety of factors, including lack of sleep, poor nutrition, dehydration, and certain medications [3]. According to BuzzRX, a healthcare website, some medications can affect workout routines, including beta-blockers, antidepressants, and antihistamines, but Lipitor is not listed as a medication that can cause fatigue during workouts [4].

In conclusion, while Lipitor is generally well-tolerated by patients and fatigue is not listed as a common side effect, it is possible that the medication may affect energy levels during morning workouts. However, more research is needed to determine if Lipitor specifically causes fatigue during exercise. Patients who experience fatigue or other symptoms while taking Lipitor should speak with their healthcare provider.
