Does Bexarotene Interact with Itraconazole?
CDI records a moderate classification for Bexarotene and Itraconazole. The stored summary is: Concomitant itraconazole could increase bexarotene plasma concentrations through CYP3A4 inhibition, though increases unlikely to cause adverse effects with gel formulations. The mechanism involves inhibition of cytochrome p450 3a4. 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.

What To Tell Your Doctor or Pharmacist
If you are taking Bexarotene and your doctor is considering prescribing Itraconazole (or vice versa), make sure to:
- Inform your doctor and pharmacist of all current medications, including over-the-counter drugs and supplements
- Ask whether the benefits of combining these medications outweigh the risks for your specific situation
- Ask what symptoms to watch for that would indicate the interaction is causing problems
- Ask whether any dosage adjustments are needed
- Never stop or change either medication without first consulting your healthcare provider
