Tangerine and Methylprednisolone

Here is the interaction we found between these two, with the evidence behind it.

Minor

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Methylprednisolone

Methylprednisolone falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Tangerine interacts with.

In vitro, tangeretin, a constituent of tangerine, induces a 52% increase in the metabolism of midazolam by cytochrome P450 3A4 (CYP3A4). This suggests that tangeretin may stimulate CYP3A4 activity. However, in humans, drinking tangerine juice 200 mL slightly delayed the absorption, but did not affect the metabolism, of midazolam, a CYP3A4 substrate. Theoretically, tangerine juice might increase CYP3A4 activity and decrease levels of drugs metabolized by this enzyme. However, this effect is unlikely.
Some drugs metabolized by CYP3A4 include amitriptyline (Elavil), amiodarone (Cordarone), citalopram (Celexa), felodipine (Plendil), lansoprazole (Prevacid), ondansetron (Zofran), prednisone (Deltasone, Orasone), sertraline (Zoloft), sibutramine (Meridia), and many others.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Good question. Your body clears methylprednisolone using a liver enzyme called CYP3A4. There's a compound in tangerine (tangeretin) that, in a lab dish, sped up that enzyme a bit. In theory, that could clear your steroid faster and make it slightly less effective at calming inflammation, swelling, or an allergic flare.

Here's the reassuring part: when researchers actually gave people tangerine juice with a similar drug, it didn't really change how the drug was broken down. So this is mostly a theoretical concern, and enjoying tangerines as food is very unlikely to weaken your methylprednisolone. If you're using concentrated tangerine extracts or notice your symptoms creeping back, just check with your pharmacist or doctor.

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.

About Tangerine

What is Tangerine?

  • Source of vitamin C
  • Digestive support
  • Aromatherapy and relaxation
  • Cough and phlegm (traditional)
  • Skin and flavoring uses

Tangerine is a sweet citrus fruit that is a good source of vitamin C and other nutrients, and is widely enjoyed as food. While the peel and essential oil are used in traditional medicine and aromatherapy, strong human evidence for specific health benefits beyond basic nutrition is limited. Enjoying tangerines as part of a balanced diet is generally safe for most people.
