Free · No account · based on published sources including NIH ODS, FDA drug labels, and peer-reviewed literature
Monitor mycophenolate drug levels closely if initiating or discontinuing Bifidobacterium supplementation. Consult with the transplant pharmacist before adding any probiotic. Report any signs of rejection or unexpected GI side effects to your healthcare provider.
Why this interaction occurs
Mycophenolate mofetil undergoes enterohepatic recirculation; gut bacteria including Bifidobacterium species produce beta-glucuronidase enzymes that can influence the reconversion of mycophenolic acid glucuronide back to the active drug. Alterations in gut microbiome composition from probiotic supplementation may theoretically affect drug bioavailability and trough levels, with implications for immunosuppression adequacy.

Reported safety data
The FDA’s adverse event reporting system (FAERS) has received 155,005 reports mentioning Mycophenolate Mofetil. This reflects reported cases involving the medication in general — not confirmed causation, and not specific to the Mycophenolate Mofetil + supplement combination on this page.
FAERS reports are voluntary and cannot prove that a drug caused an event. Do not use report counts to assess the safety of this specific drug-supplement pair.
