Check drug-drug interactions against the authoritative French ANSM thesaurus before your agent acts on a prescription or an order: post 2+ medications (CIS code, US NDC, INN/DCI substance or ANSM class) and get every published interaction between them - constraint level (contre_indication, association_deconseillee, precaution_emploi, a_prendre_en_compte), management advice and mechanism exactly as published by ANSM, plus honest coverage of anything that could not be compared. US drugs join via the INN substance bridge. No account, no key, pay per call.
