Muscle pain is a known side effect of Lipitor and ACE inhibitors, but it is not necessarily common. Lipitor (atorvastatin) is a medication used to lower cholesterol levels, and muscle pain is listed as a possible side effect in the drug's prescribing information [1]. ACE inhibitors are a type of medication used to treat high blood pressure, and they can also cause muscle pain as a side effect [2]. However, not all patients who take these medications will experience muscle pain, and the severity of the pain can vary from person to person. It is important to talk to your doctor if you experience any side effects while taking these medications. Additionally, insomnia is also listed as a possible side effect of Lipitor [3].
