9. Atorvastatin therapy may need to be discontinued if a patient experiences which of the following associated adverse reactions?
Answer: C
Atorvastatin therapy may need to be discontinued if a patient experiences muscle aches.
Muscle aches, also known as myalgia, are a significant adverse reaction associated with atorvastatin therapy and may necessitate discontinuation of the medication to prevent more severe complications such as rhabdomyolysis.
A) Hypothermia
Hypothermia is not a commonly recognized adverse reaction related to atorvastatin therapy. While it can occur due to various medical conditions or medications, it is not specifically linked to the use of atorvastatin, thus making this option incorrect.
B) Dry mouth
Dry mouth, or xerostomia, is not a typical adverse effect of atorvastatin therapy. Although it can occur with some medications, it is not significant enough to warrant discontinuation of atorvastatin, rendering this option incorrect.
C) Muscle aches
Muscle aches are a well-documented side effect of atorvastatin therapy. If a patient experiences myalgia, the medication may need to be stopped to avoid more serious muscle-related issues, making this option correct.
D) Alopecia
Alopecia, or hair loss, is not a common adverse reaction associated with atorvastatin therapy. While some medications can cause hair loss, it is not a primary concern with atorvastatin, thus this option is incorrect.
Conclusion
Muscle aches are a critical indicator that may necessitate the discontinuation of atorvastatin therapy due to the potential risk of serious muscle damage. Other options, such as hypothermia, dry mouth, and alopecia, do not present the same level of risk and are not typically associated with atorvastatin, confirming that muscle aches is the only correct answer.
