CDI records a moderate classification for Midazolam and Bicalutamide. The stored summary is: Bicalutamide co-administration increases midazolam levels 1.5-fold (Cmax) and 1.9-fold (AUC). Caution should be exercised when co-administered. The mechanism involves cyp 3a4 inhibition. 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.

- Ask whether any dosage adjustments are needed
- Never stop or change either medication without first consulting your healthcare provider
