Isidorey uses Twilio to power its smart pill packages for Stora Enso by sending SMS messages through the platform, which are then processed on Isidorey's end and integrated with Google Health, MDClick, and Dossia for electronic health records. The project aims to solve the problem of prescription compliance without requiring additional hardware or software intervention. Isidorey has been working with Twilio for some time and leveraged its API to develop a customized solution that meets their specific needs, allowing them to track prescription lifecycles and fill prescriptions without user interaction.
