Tangerine and Fluticasone Propionate

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

Minor

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Fluticasone Propionate

Fluticasone Propionate 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.

Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans..

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the short version: tangerine and your fluticasone (Flonase, Xhence, Armonair) really don't have a meaningful interaction to worry about. Fluticasone is broken down by an enzyme called CYP3A4, and lab studies hinted that a compound in tangerine (tangeretin) might speed that enzyme up a bit. In theory, faster breakdown could lower fluticasone levels and make it slightly less effective for your allergy or nasal symptoms.

But here's the reassuring part: when people actually drank tangerine juice in a human study, it did not change how the enzyme handled the medication. The evidence is weak and the effect is considered unlikely. Eating tangerines as food is fine. If you ever notice your symptoms creeping back, just check in 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.

From our pharmacist’s overview on the Fluticasone Propionate page

“Fluticasone propionate (Flonase, Xhance, Armonair Respiclick) is a corticosteroid for allergies and asthma, and because the body clears it through the CYP3A4 enzyme, I would treat this page with genuine care rather than a passing glance. Of the 141 ingredients on file, 121 can nudge that enzyme in one direction or the other, which can…”

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.
