What would be a priority action if a client shows signs of myopathy while taking atorvastatin?

When a client exhibits signs of myopathy while taking atorvastatin, the priority action is to withhold the medication and notify the healthcare provider. Myopathy, which can range from mild muscle aches to a serious condition like rhabdomyolysis, indicates that the muscle tissues are being affected adversely by the medication. Given the potential for severe muscle damage that can arise from further exposure to atorvastatin, immediate intervention is crucial to prevent further harm.

Withholding the medication allows for the assessment of symptoms, diagnostic tests to evaluate muscle damage, and consideration of alternative treatment options. Additionally, notifying the provider ensures that appropriate adjustments to the treatment plan can be made based on the client's current status. This action prioritizes client safety and aligns with best practices in managing medication-related adverse effects.
