Muscle pains can be a potential side effect of taking Lipitor (atorvastatin), a medication used to lower cholesterol levels [1]. Additionally, ACE inhibitors, a class of medications commonly used to treat high blood pressure, can also cause muscle pain as a side effect [2]. It is important to note that while muscle pain can occur with these medications, not everyone will experience this side effect. If you are experiencing muscle pains while taking Lipitor or ACE inhibitors, it is advisable to consult with your healthcare provider for further evaluation and management.
