MedicationInteractionChecker: Pharmacy Cross-Reference
Real-time drug interaction warnings for patients taking multiple medications from different pharmacies or prescribers
The Problem
People managing chronic conditions often see multiple doctors and fill prescriptions at different pharmacies, creating dangerous blind spots where dangerous drug interactions go undetected. Pharmacies only check interactions within their own system, missing interactions from medications prescribed elsewhere or purchased over-the-counter.
Target Audience
People 55+ managing 3+ medications, caregivers managing elderly parents' prescriptions, patients with complex medical histories seeing multiple specialists
Why Now?
LLMs + OCR tools make medication label parsing trivial; free public drug databases (DrugBank, FDA) are more accessible; patient frustration with fragmented pharmacy systems is peak
What's Missing
Existing solutions are either enterprise software locked behind pharmacies, or generic pill trackers that don't genuinely solve the multi-pharmacy problem. Patients have no simple way to check interactions across their full medication list.
