Based on the information provided, I can tell you that Lipitor (atorvastatin) is a medication used to treat high cholesterol and prevent heart disease [1]. Common side effects of Lipitor include diarrhea, upset stomach, and muscle pain [1]. However, the available information does not specifically mention muscle cramps as a common side effect of Lipitor [1][2].

It is important to note that everyone's reaction to medication is different, and some people may experience side effects not listed in the drug's official information. If you are taking Lipitor and are experiencing muscle cramps or any other unusual symptoms, it is recommended that you speak with your healthcare provider [1].

In summary, while muscle pain is a known side effect of Lipitor, muscle cramps are not specifically listed as a common side effect of the medication [1][2]. It is always important to consult with a healthcare provider regarding any concerns about medication side effects.
