For safe prescribing plus emergency clinical protocols and drug-interaction checking, I’d shortlist UpToDate with Lexidrug and Micromedex first. They are established clinical decision-support resources, but they serve slightly different needs.
My recommendation depends on whether you need a single everyday reference for clinical decisions or a more specialized tool for emergency medicine, toxicology, and medication safety.
Best tools to consider
1. UpToDate with Lexidrug
(Best overall starting point)
Strong for day-to-day prescribing, evidence-based treatment recommendations, dosing, contraindications, and drug–drug interactions. It also includes guidance on renal and hepatic dose adjustments, pediatric dosing, and medication monitoring.
