Drug Interaction Report

Consumer information for this interaction is not currently available.

MONITOR: Concomitant use of orally and rectally administered formulations of budesonide with inducers of CYP450 3A4 may decrease budesonide systemic as well as local exposure at the gut mucosa. Budesonide undergoes extensive first-pass and systemic metabolism via intestinal and hepatic CYP450 3A4. Although clinical and pharmacokinetic data are currently lacking, such an interaction may impact the therapeutic efficacy of budesonide in the treatment of inflammatory bowel disease.

MANAGEMENT: The potential for diminished pharmacologic effects of orally and rectally administered budesonide should be considered during concomitant treatment with drugs that induce CYP450 3A4. Alternative treatments or budesonide dose adjustments may be required if an interaction is suspected.

You should avoid the regular consumption of large amounts of grapefruits and grapefruit juice while taking budesonide. Grapefruit can raise the levels of budesonide in your body and lead to increased side effects. Do not increase or decrease the amount of grapefruit products in your diet without first talking to your doctor.
