Step-by-step explanation:
The career focus for a pharmacist involves the dispensing of drugs prescribed by a doctor and requires thorough knowledge in chemistry and biology. In the U.S., pharmacists must earn a doctorate in pharmacy and obtain a state license for the state in which they choose to practice.
This academic journey generally involves four years of specialized education at a pharmacy school. After the necessary education, pharmacists play a critical role in the healthcare system by advising physicians on drug selection, dosage, interactions, and side effects, as well as instructing patients on the correct usage of their medications. Their extensive knowledge in sciences enables pharmacists to work in diverse settings such as drugstores, hospitals, and medical facilities.
