Question 76

A pharmacist should be consulted if a patient has a current prescription for atorvastatin.

When a computer alert indicates that a patient has a current prescription for atorvastatin, it is crucial for the pharmacist to be consulted. Atorvastatin and Crestor (rosuvastatin) are both statins, and concurrent use could increase the risk of adverse effects such as muscle toxicity.

A) an allergy to sulfa drugs

An allergy to sulfa drugs is not relevant in this context since Crestor is not a sulfa drug. Therefore, while an allergy must always be noted, it does not necessitate consultation with the pharmacist in relation to this specific prescription.

B) been prescribed 10 mg per day

The dosage of 10 mg per day does not raise an immediate concern that warrants pharmacist consultation. The pharmacist would review the appropriateness of the dose, but this alone does not trigger a significant alert that would require further discussion.

C) no history of liver disease

Having no history of liver disease is generally a positive indication when prescribing statins like Crestor. This condition would not cause an alert that necessitates pharmacist intervention, as it suggests that the patient is likely a suitable candidate for the medication.

D) a current prescription for atorvastatin

A current prescription for atorvastatin is a critical factor that requires pharmacist consultation. Both atorvastatin and Crestor belong to the same class of cholesterol-lowering medications, and taking them together can increase the risk of side effects and drug interactions, highlighting the importance of careful monitoring.

Conclusion

The need for pharmacist consultation arises primarily from the potential interactions and risks associated with concurrent use of atorvastatin and Crestor. Options A, B, and C do not present significant concerns that would warrant further discussion, making D the definitive choice. Understanding the implications of drug interactions is essential for patient safety in pharmaceutical care.
