Clinical interactions & pharmacogenomics
Drug interaction checker
Enter up to four medications. The tool checks every pair against a curated library sourced from FDA labels and CPIC Guidelines, and flags pharmacogenomic differences that matter for Black patients (CYP2C19, CYP2D6, VKORC1, ADRB2).
How to use this tool
- Start typing a medication name in the first box — generic or brand works.
- Pick from the suggestions. Repeat for each medication you take.
- Click Check interactions.
What it checks
- Major, moderate, and minor drug–drug interactions between medications in our library.
- Pharmacogenomic flags on single drugs with a well-documented Black-patient signal.
- Links to the full page for each medication on blackhealth.org.
Always talk to your pharmacist. This tool is educational and only surfaces interactions we can cite. Pharmacy software checks every combination in your full medication regimen against continually-updated databases like Lexicomp and Micromedex — use this tool to sharpen the questions you bring to that conversation, not to replace it.
