An online resource and database where consumers can look up prescription medications, dosages, side effects, and interactions.
Modern internet-age acronym representing 'Ex' (possibly 'exchange' or generic prefix) + 'Rx' (the pharmaceutical symbol for prescription). Emerged in early 2000s as a public health website.
ExRx transformed healthcare—suddenly people could fact-check their doctors and discover weird drug interactions before filling prescriptions, moving pharmaceutical knowledge from doctor-exclusive to publicly searchable.
