RxGuard

RxGuard analyzes drug-interaction risk using FAERS (FDA Adverse Event Reporting System) data and semantic search. Describe a patient's medication regimen in plain English and the system extracts drugs, demographics, and conditions, then retrieves dangerous interactions, contraindications, and real FDA adverse-event cases — ranked by severity and matched by semantic meaning rather than keywords. It ships multiple search backends with progressively better understanding: keyword exact-match (baseline), TF-IDF + cosine similarity, and vector search with sentence-transformers.
