ISI: Important Safety Information

I led UX to standardize Pfizer’s ISI across 150+ sites, boosting patient adherence by improving clarity and reducing errors while meeting FDA guidelines. Using the Helix Design System, we turned a fragmented experience into a scalable, trusted, and user-friendly standard.

The goal

Improve comprehension, reduce medication errors, and boost engagement by standardizing Pfizer’s Important Safety Information (ISI) component through the Helix Design System—making it clearer, more accessible, and less intrusive across patient-facing sites.

The challenge

Outdated FDA guidelines and inconsistent ISI designs across 150+ brand websites created confusion and risk. Unifying these experiences required balancing strict regulatory requirements with usability and design consistency at scale.

Bridging regulation and user experience

I collaborated with medical, legal, and regulatory teams to translate complex FDA guidance into a user-friendly, compliant ISI experience. Through audits and user testing, I identified key pain points and focused on improving clarity, readability, and accessibility.

I designed a scalable ISI component using design tokens and built high-fidelity prototypes with clear documentation. To support adoption, I hosted trainings, led office hours, and partnered with product teams—driving alignment across platforms and laying the foundation for an industry-first design standard proposed to the FDA.
