What symptom should a nurse emphasize for a client starting atorvastatin to report?

When initiating treatment with atorvastatin, it is crucial for clients to be aware of certain side effects, particularly those related to muscle health. Muscle pain, also known as myopathy, is a potential adverse effect associated with statin therapy, including atorvastatin. If a client experiences unexplained muscle pain or weakness, it could indicate the onset of a more serious condition called rhabdomyolysis, which can lead to kidney damage if not addressed promptly.

The emphasis on reporting muscle pain is critical because it allows for early detection and intervention, potentially preventing serious complications. Understanding this risk helps ensure that the nurse can monitor the client effectively and adjust treatment as necessary, ensuring the safety and well-being of the client while managing their cholesterol levels.
