Drug interaction check

Enter 8 drugs at most (at least two): we show whether they mention each other in official labels (US FDA/openFDA + Türkiye SmPC), with the evidence passage for every pair.

This is a name and class scan, not a complete interaction database. “Not found” does not mean there is no interaction. It does not diagnose, and it is not for emergencies or time-critical situations.

What we scan and what we do not
We scan: the interaction, contraindication, boxed-warning and warnings sections of the official labels of the drugs you enter (openFDA and Türkiye SmPC) — for every pair separately, does the other drug’s name or class appear.
We do not scan: food, alcohol, herbal and supplement interactions. Real interactions that are not written in the label are also out of scope. Cumulative risks that arise with three or more drugs are out of scope too — the scan compares drugs two at a time.
Because no openly licensed commercial interaction database exists, this tool is not a database query but a name and class scan of official label texts. We show the passage so you can review the basis yourself.
