Does Stiripentol Interact with Phenytoin?

CDI records a moderate classification for Stiripentol and Phenytoin. The stored summary is: Phenytoin is a strong inducer of CYP1A2, CYP3A4, and CYP2C19 and may decrease DIACOMIT concentrations. Concomitant use should be avoided or dosage adjustment made. The mechanism involves cyp1a2, cyp3a4, and cyp2c19 induction. Patients taking both medications should consult their healthcare provider before starting, stopping, or changing the dosage of either drug. This record was extracted from drug labeling through openFDA. NIH/NLM RxNorm is used for drug identities. The summary and severity classification are CDI's processed information, not a verbatim source quotation. Product, route, and patient circumstances matter.

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.
