A pharmacy technician is processing a prescription for Crestor. The pharmacist should be consulted if a computer alert indicates that the patient has:

Rationale

a current prescription for atorvastatin.

Crestor (rosuvastatin) and atorvastatin are both statins used to lower cholesterol levels, and they should not be used concurrently due to the increased risk of adverse effects. If a patient has a current prescription for atorvastatin, it is crucial to consult the pharmacist to prevent potential drug interactions and ensure patient safety.

A (an allergy to sulfa drugs) YOUR ANSWER

Crestor is not a sulfonamide, and therefore, an allergy to sulfa drugs does not directly impact the safety of prescribing Crestor. While it is important to be aware of all allergies, this specific allergy does not warrant a consultation with the pharmacist regarding the Crestor prescription.

B (been prescribed 10 mg per day) YOUR ANSWER

The prescribed dosage of 10 mg per day for Crestor is within the recommended dosing guidelines. This information alone does not indicate a need for pharmacist consultation, as it is not a contraindication or a potential risk factor that requires further discussion.

C (no history of liver disease) YOUR ANSWER

While liver disease can impact the safety and efficacy of statin therapy, the absence of a history of liver disease does not require consultation with the pharmacist. This information suggests that the patient may be a suitable candidate for Crestor and does not raise any immediate concerns.

D (a current prescription for atorvastatin) CORRECT

Having a current prescription for atorvastatin raises significant concerns about drug interactions and safety, as both atorvastatin and Crestor belong to the same class of medications. Consulting the pharmacist is essential to avoid the risk of increased side effects, including myopathy and liver toxicity.

Conclusion

In the context of processing a prescription for Crestor, the most critical factor that necessitates pharmacist consultation is the patient’s current prescription for atorvastatin. This situation poses a risk of drug interactions and potential adverse effects. Other choices, such as allergies and dosages, do not present the same level of urgency or concern. Ensuring patient safety by consulting with the pharmacist in cases of overlapping statin therapy is a crucial aspect of responsible pharmaceutical care.
