How this information is prepared: CDI uses automated extraction, including AI, to summarize drug labeling from openFDA and includes separately identified curated-reference records. RxNorm helps identify medications; it does not verify interaction claims. Extracted summaries and CDI severity classifications can contain errors and are not verbatim FDA statements or independent clinical review. Maintained by CheckDrugInteractions.com. See our methodology or report a correction at support@checkdruginteractions.com.

Data sourced from U.S. FDA drug labeling via openFDA and the NIH National Library of Medicine, supplemented with a small number of well-established interactions from curated clinical references. For informational purposes only. Always consult your pharmacist or physician.
