Enhancing Medication Adherence in Remote Areas Using a GSM-Based Reminder System

Ensuring timely medication intake and regular health check-ups is crucial for effective treatment, especially among elderly patients and those in rural areas. However, limited access to internet services and complex technologies often hinders adherence to medical schedules. This paper presents an enhanced Patient Reminder System that utilizes GSM technology to deliver scheduled SMS alerts for medications, doctor visits, and other health-related tasks. The system is built using a microcontroller, a GSM module, a keypad for user input, and a real-time clock to ensure timely notifications. Designed to operate independently of internet connectivity, the solution is affordable, user-friendly, and highly suitable for remote or resource- constrained environments. The modular design also allows for future integration with IoT sensors and cloud platforms for real- time monitoring and data analysis. Overall, this system aims to improve patient compliance, reduce missed treatments, and support caregivers in delivering timely healthcare reminders.
