Final answer:
A pharmacist must be licensed by the state in which the non-resident pharmacy is situated. They need a doctorate in pharmacy and must pass state-specific exams. Their role is critical in understanding medication effects and advising on drug usage.
Step-by-step explanation:
A pharmacist must be licensed in the state where the non-resident pharmacy is located to legally dispense prescription drugs. In the United States, it's essential for a pharmacist to hold a doctorate in pharmacy and obtain licensure in any state where they intend to practice. Licensing requirements are not only a matter of completing a doctorate degree but also passing a series of exams specific to the state's regulations.
Given that pharmacists must have a deep understanding of chemistry and biology, their expertise ensures that they comprehend the interactions and effects of medications on the human body. This knowledge is vital for advising both physicians and patients on medication usage. Pharmacists can work in various settings such as drugstores, hospitals, and other medical facilities, and although they used to compound drugs themselves, this is now a rare part of the job.
