A client taking atorvastatin presents to the clinic reporting acute muscle pain not associated with exercise or injury. The nurse asks questions to determine if this client has been taking what contraindicated substance?

A. Ibuprofen: Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID), but it is not contraindicated with atorvastatin. However, combining NSAIDs and statins may increase the risk of kidney issues over time, but it does not typically cause muscle pain. B. Ginseng: Ginseng can interact with some medications, but it is not commonly linked to muscle pain when taken with atorvastatin. There is no direct contraindication between atorvastatin and ginseng that would cause this symptom. C. Grapefruit juice: Grapefruit juice is known to interact with atorvastatin and other statins, potentially increasing the drug's blood concentration. This interaction can lead to a higher risk of side effects, including muscle pain, weakness, and rhabdomyolysis, which are serious symptoms of statin toxicity. D. Saw palmetto: Saw palmetto is typically used for prostate health, and while it can interact with some medications, it is not known to cause muscle pain when taken with atorvastatin. There is no significant contraindication
