About Check Drug Interactions (CDI)

Why CDI exists

Making publicly funded drug information genuinely accessible to the public.

Drug information can be difficult to navigate when it lives in technical documents. CDI helps patients and caregivers search a medication list, explore documented interactions, and find the evidence behind a result.

Built around everyday tasks

• Check up to 20 medications and review every pair.
• Find drug names with autocomplete or scan a medication label with a camera.
• Review severity-ranked results and share a list with a caregiver or clinician.
• Read source information alongside accessible explanations.

Public sources, transparent processing

Our interaction data comes primarily from FDA drug labeling through openFDA. NIH/NLM RxNorm helps standardize drug names. Limited curated-reference records supplement specific gaps and are tagged separately.

CDI processes and presents that information. Extracted summaries and educational explanations are not verbatim label text. We describe source handling, severity classification, and limitations in our methodology.

Explain, and make it verifiable

AI-assisted writing may explain supported information. It must not invent interaction claims, citations, or severity ratings. Read our editorial policy and source-linked explanations.

Limits and accountability

CDI is an independent project, not an FDA or NIH service or endorsement. Our coverage depends on source availability and our extraction process. A missing result is not proof of safety, and this tool does not replace a pharmacist or physician who knows your situation.
