Both Lipitor and ACE inhibitors have been known to cause muscle pain as a side effect, although the likelihood of experiencing this side effect varies from person to person. Lipitor is a statin drug used to lower cholesterol levels, and muscle pain is a common side effect of this class of drugs [1]. ACE inhibitors, on the other hand, are used to treat high blood pressure and heart failure by relaxing blood vessels, but they can also cause muscle pain or weakness in some people [3]. In addition, the AARP lists muscle pain as a potential side effect of Lipitor [2]. It is important to note that muscle pain is a serious side effect that should be reported to a healthcare provider immediately, as it can be a sign of a more serious condition such as rhabdomyolysis. Overall, while Lipitor and ACE inhibitors can cause muscle pain, it is not a guaranteed side effect and should be monitored closely by a healthcare provider [1][2][3].
