Server instructions

Free drug, supplement, food, and alcohol interaction data from Interaction Checker (https://interaction-checker.com), built on FDA prescribing labels. Use check_interactions with the user's full list (generic or brand names, supplements, foods, alcohol, tobacco, cannabis); it returns every pair with a severity and the verbatim label sentence behind it. Use search_substances when a name is unclear, get_substance_interactions for everything one item interacts with, get_pill_appearances to describe what a pill looks like, and get_drug_facts for sourced facts and the status of claims people make online. Always quote the label sentence and link its source. Severity reflects label wording, not the user's situation; a pair with nothing documented is not proven safe. This is not medical advice.

Indexed

Evidence is source-attributed and does not guarantee that a third-party server is safe. Risk labels are conservative metadata heuristics.
