Muscle aches are a commonly reported side effect associated with the use of Lipitor (atorvastatin), a medication used to treat high cholesterol levels. According to the Lipitor medication guide provided by the FDA, muscle pain or weakness is a potential side effect of this drug [1]. Moreover, DrugPatentWatch.com also lists muscle pain as a common side effect of Lipitor [2]. However, it is crucial to note that not everyone who takes Lipitor will experience muscle aches, and the presence of this symptom does not necessarily indicate a severe issue.

Muscle aches may be a sign of a rare but serious side effect called rhabdomyolysis, a condition in which muscle tissue breaks down and releases a damaging substance into the bloodstream. If you experience muscle pain, tenderness, or weakness along with fever, dark-colored urine, or unusual tiredness, you should seek medical attention immediately [1].

In summary, muscle aches can be a normal side effect of Lipitor use, but it is essential to monitor the severity and duration of the muscle pain and consult a healthcare professional if necessary.
