They give advise on the selection, dosages, interactions, and side effects of medications. Pharmacists in community pharmacies answer customers' questions about prescription drugs, such as possible adverse reactions and interactions. Pharmacists in hospitals and clinics dispense medications and advise the medical staff on the selection and effects of drugs. At least 5 years of study beyond high school are required to obtain a B. S. degree in pharmacy. A doctor of pharmacy degree normally requires at least 6 years.
