Interaction report

Evodia and Deferasirox

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Evodia interacts with whole categories of medication. Deferasirox falls into 2 of those categories, so it can interact with Evodia in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

CYTOCHROME P450 1A2 (CYP1A2) INHIBITORS

1 of 2

Why this applies to Deferasirox

Deferasirox falls under CYTOCHROME P450 1A2 (CYP1A2) INHIBITORS — the group Evodia interacts with.

Theoretically, drugs that inhibit CYP1A2 might increase the levels and clinical effects of evodia.
The evodia constituent rutaecarpine is metabolized by CYP1A2.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the thing to know about pairing Evodia with deferasirox (Exjade, Jadenu). This interaction runs in one direction: deferasirox can block a liver enzyme called CYP1A2, which is the same enzyme that breaks down one of Evodia's active compounds (rutaecarpine). So if you take both, the Evodia compound may clear more slowly and build up, meaning more of the supplement's effects, not the drug's.

Deferasirox itself is not a prodrug, and its usual issues (stomach upset, nausea, kidney or liver effects) shouldn't change here. Honestly, this is only theoretical, based on lab work, so it may not matter much in real life. Still, since we don't know much about Evodia in people, please check with your pharmacist or doctor before combining them.

CYTOCHROME P450 3A4 (CYP3A4) INDUCERS

2 of 2

Deferasirox also falls under CYTOCHROME P450 3A4 (CYP3A4) INDUCERS.

Theoretically, taking CYP3A4 inducers might decrease the levels and clinical effects of evodia.
Animal research shows that concomitant administration of dexamethasone, a known CYP3A4 inducer, with the alkaloid constituents of evodia significantly reduces the area under the curve (AUC), maximum concentration (Cmax), and half-life of these constituents.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the thing to keep straight with this pairing: the interaction runs in one direction. Deferasirox can act as a mild inducer, meaning it can speed up a liver enzyme (CYP3A4) that helps break down Evodia's active compounds, like evodiamine and rutaecarpine. So if anything, your Evodia may get cleared out faster and work less well, not the other way around.

Importantly, this is based only on lab and animal studies, so it's theoretical and not something to lose sleep over. Your deferasirox should keep doing its job of pulling excess iron out of your body either way. Since human data is thin and Evodia itself isn't well studied, just loop in your pharmacist or doctor before combining them.

What These Ratings Mean

Every interaction above is graded three ways — here’s the key to each label.

Severity how clinically significant the interaction is
Major

Clinically significant. Avoid the combination, or use only under close professional supervision.

Moderate

Usually worth avoiding or managing — may need monitoring, a dose change, or timing apart.

Minor

Generally not serious. Be aware of it and mention it to your pharmacist.

Likelihood how strong the evidence is that the interaction actually happens in people
  • LikelyWell-controlled human studies have demonstrated the likely existence of this interaction.
  • ProbableInteraction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • PossibleInteraction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).
  • BCase-control study.
  • CConsensus.
  • DAnecdotal evidence.

These ratings are for information only. Never start, stop, or otherwise change your therapy before speaking with your provider.

About Deferasirox

What Is Deferasirox Used For?

Brand names: Exjade, Jadenu

Deferasirox — available as tablets (including Exjade and Jadenu) and oral powder granules (including Jadenu) — is used to treat chronic iron overload in patients 2 years and older whose bodies have accumulated too much iron from repeated blood transfusions.

It is also used to treat chronic iron overload in patients 10 years and older who have non-transfusion-dependent thalassemia (NTDT) syndromes — a group of inherited blood disorders — when liver iron levels and blood ferritin levels meet specific thresholds. The safety and effectiveness of deferasirox when combined with other iron-chelation therapies have not been established.
