Pharmacists dispense medications, verify prescriptions, identify interactions, and guide patients on safe and effective drug use. They collaborate with physicians, monitor therapy outcomes, ensure regulatory compliance, and support chronic-disease management. The role involves pharmacovigilance, inventory oversight, and patient education. Pharmacists work in community pharmacies, hospitals, ambulatory clinics, and public health programs. They increasingly contribute to vaccination services, medication therapy management, antimicrobial stewardship, and digital-health initiatives. Global demand continues to rise due to ageing populations, expanded clinical roles, and growth in pharmaceutical services.
