Pharmaceutical Patient Adherence Multi-Channel

GSK Reminders Turning Unfilled Prescriptions
Into Refills at Scale

Medication non-adherence costs the pharmaceutical industry $637 billion annually — nearly one-third of all prescriptions never get filled. We built a multi-channel reminder system for GSK that reaches patients through SMS, email, and fax at the exact moment they need to refill, processing up to 1,000 messages per minute.

The Challenge

Here's a staggering reality: up to 50% of all prescribed medications are not taken as prescribed. Nearly one-third of prescriptions are never filled at all. For pharmaceutical giants like GSK — one of the world's largest pharma companies with $32 billion in annual revenue — this isn't just a patient health crisis. It's a business catastrophe.

The math is brutal. HealthPrize Technologies estimates that medication non-adherence costs the pharmaceutical industry $637 billion annually in lost revenue. That's not a typo. For chronic condition medications especially, the average lost-revenue percentage is 59%. Patients start a medication, feel better, and stop refilling — or they simply forget.

GSK needed a system that could reach patients at scale through multiple channels — SMS, email, and even fax for healthcare providers — with timely reminders to refill their prescriptions. But this wasn't just about blasting messages. It required sophisticated scheduling, dose management, legal compliance, two-way communication, and the ability to handle massive throughput without missing a beat.

Massive Scale Requirements

Reaching millions of patients requires infrastructure that can send up to 1,000 text messages per minute without delays or failures during peak refill windows.

Pharmaceutical Compliance

Every message requires precise legal disclaimers and opt-out mechanisms. Centralized footer management ensures compliance across millions of communications.

Two-Way Communication

Patients need to reply, ask questions, and interact — not just receive one-way broadcasts. The system had to support real two-way conversations at scale.

Our Approach

We designed GSK Reminders as a multi-channel communication engine built for pharmaceutical-grade compliance and consumer-grade experience. The system manages the full lifecycle from dose scheduling to reminder delivery to patient response handling.

01

Multi-Channel Delivery

Patients respond differently to different channels. Some prefer SMS, others email, and healthcare providers often need fax. We built a unified system that delivers through all three with consistent messaging and tracking.

02

Intelligent Scheduling Engine

Different medications have different refill cycles. The system manages doses, SKUs, and reminder schedules — calculating exactly when each patient needs to refill based on their specific prescription and dosing pattern.

03

High-Throughput Architecture

To reach patients at scale, we built infrastructure capable of sending 1,000 SMS messages per minute with mass email queueing and batch processing — handling peak loads without degradation.

04

Compliance-First Design

Centralized legal footer management ensures every message includes required disclaimers. Advanced template management allows marketing to control messaging while legal controls compliance elements.

"Medication non-adherence isn't just a health problem — it's a $637 billion business problem for the pharmaceutical industry. Every unfilled prescription is a patient who doesn't get better and revenue that never materializes. Timely, multi-channel reminders delivered at scale can change both of those outcomes."
