The Department of Pharmacy is the department that specializes in studying medicines and medical drugs, and how to prepare, manufacture, store and distribute them. The pharmacist's work is related to providing medication advice to patients and working to provide the necessary health care by providing the correct medications using the correct and appropriate doses. The pharmacist's duties also include monitoring the effect of medications on patients and ensuring that no harmful drug interactions occur. In addition, the pharmacist instructs patients on how to use medications correctly, and makes them aware of possible side effects that may occur. The work of a pharmacist requires comprehensive knowledge of chemistry, biology and technology, and needs good communication skills to interact with patients and other healthcare teams.
