Prescribers remain divided on generic substitution of narrow therapeutic index (NTI) drugs like warfarin and levothyroxine. While FDA data supports safety, real-world experience shows risks in stability, monitoring, and communication. State laws, physician preferences, and patient outcomes all shape substitution practices.

Retail and hospital pharmacies handle medication substitution differently-retail focuses on cost and patient choice, while hospitals prioritize clinical safety and team-based decisions. Understanding these differences helps patients avoid dangerous mix-ups.
