The GoodRx Data Problem
Coupon platforms are not free. You pay with your prescription history.
- FTC action (2023): GoodRx was fined $1.5M for sharing user health data — including prescription information — with Facebook, Google, and Criteo ad platforms without consent.
- PBM revenue model: GoodRx's largest revenue stream is fees from pharmacy benefit managers — the same entities that inflate Colistin prices. The "free" coupon is subsidised by the PBM industry.
- Permanent profile: Every Colistin fill run through a coupon platform joins your health-data profile — sold to data brokers even after you delete the app.
- Script Unlock model: Pharmacies pay a flat fee when they win a bid. We never see, sell, or share your prescription data.
