Methodology

Package decisions that can be replayed and inspected.

RecalledMeds separates discovery, evidence and package matching. That separation keeps a convenient search result from being mistaken for an exact package conclusion.

Evidence before interpretation

Source documents are retained as immutable versions with a content hash, retrieval time, parser version and normalized facts. A correction creates a new version or supersession relationship. It does not silently rewrite the evidence that supported an earlier check.

Deterministic package matching

Package inputs are normalized using versioned rules. NDC candidates preserve the ambiguity of current 10-digit presentations rather than assuming an unverified segmentation. Lot comparisons support exact values, source-defined prefixes, numeric ranges and explicit all-lot rules. Each field contributes a recorded reason to the result.

Eight distinct results

Confirmed, probable, package-verification, related, manufacturer-pending, conflict, no-indexed-match and insufficient-information states remain separate. A no-indexed-match result is bounded by the source systems and versions checked and never means a product is safe.

Human review and AI

Ambiguous and high-risk conflicts enter a credentialed review workflow. AI can help extract a strict schema, compare recorded text and explain a result. AI cannot assign FDA status, decide an exact package match or replace cited source evidence.

Jurisdiction

The launch service reports U.S. status. Foreign regulator information may corroborate or provide context, but it cannot become a U.S. recall without U.S. authority.
