For the prescription: Prozac 20 mg #30 qd NR, how many refills are allowed?

The prescription for Prozac, typically written for a specific number of tablets and a daily dosage, is important to consider in the context of refills. In this case, "qd" indicates that the medication is to be taken once daily, while "NR" stands for no refills. This specific notation is crucial because it explicitly instructs that the patient should not have any refills on this prescription after the initial supply of 30 tablets.

In many states and for certain medication types, particularly those that may be controlled substances or require careful monitoring, there are strict regulations regarding refills. Thus, when "NR" is listed—meaning "no refills"—it indicates that once the 30-tablet supply has been dispensed, the patient must return to the prescribing physician for a new prescription rather than being able to refill this one.

Therefore, based on standard prescribing practices and the specific instruction within the prescription, the correct answer is that no refills are allowed.
