Editorial Policy

Our Sources of Truth

The drug interaction data on this site — every severity rating, description, and mechanism — is extracted directly from official U.S. FDA drug labeling made available through OpenFDA and DailyMed, with drug names standardized against RxNorm from the U.S. National Library of Medicine.

We do not invent, infer, or editorialize interaction data. If an interaction is listed, it is documented in an FDA-approved label. If no interaction is shown, none was found in our source data — which is not the same as a guarantee of safety. The full extraction and classification process is documented on our Methodology page.

How Our Educational Articles Are Produced

Beyond the interaction database, we publish plain-language educational articles that explain how medications work together, what severity levels mean, and what questions to ask a pharmacist. These articles are grounded in the same FDA labeling data and other publicly available, authoritative sources such as PubMed and FDA safety communications.

Disclosure of AI assistance: our educational articles are drafted with the help of AI writing tools, working strictly from FDA-sourced facts and cited references. We disclose this because transparency about how content is created is part of publishing responsibly. Articles are intended as general education, are clearly dated, and are never a substitute for individualized advice from a licensed professional.

What This Site Is — and Is Not

CheckDrugInteractions.com is an informational reference tool. It is not a healthcare provider, does not offer personalized medical advice, and does not establish a patient–provider relationship. Nothing on this site should be used to start, stop, or change a medication. Always consult your physician or pharmacist, who can weigh your specific health conditions, doses, and full medication list.

Accuracy and Corrections

We take accuracy seriously. If you find an error, an outdated entry, or a missing interaction, email support@checkdruginteractions.com. We investigate every report against the underlying FDA source and correct or remove content that cannot be verified. Our data pipeline also re-runs periodically to incorporate new and revised FDA labels.

Advertising Independence

This site is free and supported by advertising. Advertisers have no influence over our interaction data, severity classifications, or editorial content. Ads are clearly distinguishable from content, and no interaction result is ever altered, promoted, or suppressed for commercial reasons.
