Micromedex is a comprehensive clinical decision support database now owned by Merative (formerly IBM Watson Health, and before that Truven Health Analytics). It is one of the most widely recognized drug information resources in healthcare, used by hospitals, health systems, poison control centers, and academic institutions around the world.
The Micromedex platform encompasses far more than drug interactions. It includes detailed drug monographs covering pharmacokinetics, dosing guidelines, adverse reactions, and off-label use data. It also covers toxicology information through POISINDEX, IV compatibility data via TRISSELS, and disease-specific treatment protocols. Drug interaction checking is one module within this much larger clinical reference suite.
Micromedex is typically sold through enterprise site licenses, often bundled as part of a hospital or health system's broader clinical information infrastructure. Pricing is not publicly listed and generally requires a formal procurement process involving vendor evaluation, contract negotiation, and institutional approval -- a cycle that can take weeks or months to complete.
For teams that need the full breadth of clinical reference data, Micromedex remains a strong choice. But for teams that specifically need programmatic access to drug interaction data -- particularly through a modern REST API with self-service onboarding -- the enterprise-scale platform may be more than what is needed.
