Final answer:
A pharmacist can fill an RX written by an out-of-state prescriber if it is filled within the pharmacist's state of practice. This may be subject to state-specific laws and regulations, but some states have reciprocity agreements allowing pharmacists to fill out-of-state prescriptions.
Step-by-step explanation:
A pharmacist can fill an RX (prescription) written by an out-of-state prescriber if it is filled within the state in which the pharmacist is licensed to practice. Pharmacists in the United States must hold a doctorate in pharmacy and be licensed by the state in which they work. This means that they are governed by the laws and regulations of that specific state. So, if a pharmacist is licensed in one state, they may not have the legal authority to fill a prescription from an out-of-state prescriber. However, some states have established agreements and reciprocity laws that allow pharmacists to fill prescriptions from out-of-state prescribers. These agreements ensure that the pharmacist is following the appropriate guidelines and regulations when dispensing medications.
