Build the intended prescription alongside the patient's current medications. Interactions are grouped by where they arise - within what you are starting, between a new medicine and an existing one, or already present in the current regimen.
Build the patient's current regimen, choose the medicine to reconsider, and select why. The tool proposes same-class or recognized alternative-class options and screens each against the interactions, cross-reactivity patterns, and side-effect and food cautions recorded in this teaching set. It is decision support - confirm the indication, current evidence, dose equivalence, and patient specifics before switching.
