A pharmacist is responsible for dispensing and managing medications, educating patients on correct usage of drugs and potential drug side effects, and managing the overall health care or well-being of patients/customers in the setting of pharmacies and dispensaries. Pharmacists must know how to handle medications for patient safety and how to give correct dosages. Interaction with patients is common, so pharmacists may need to answer questions about medication. Furthermore, it is the duty and legal obligation of all pharmacists to know and follow the laws pertaining to the prescribed medication, and make sure that no medication is dispensed to a patient that would create a medical/drug interaction with any other medications that the patient is also taking. Staying abreast of new research in pharmaceutical developments and their safety is of vital importance in pharmacy jobs.
