Tangerine and Colchicine

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

Minor

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Colchicine

Colchicine 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.
Severity Minor Likelihood Unlikely Evidence B

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist with colchicine and tangerine. Colchicine is cleared from your body partly by an enzyme called CYP3A4. One lab study hinted that a compound in tangerine (tangeretin) might speed that enzyme up a bit, which in theory could nudge colchicine out of your system faster and make it work a little less well. But when researchers actually tested tangerine juice in people, it didn't meaningfully change how the enzyme handled a similar drug.

So this is mostly a theoretical concern, rated minor and unlikely. Eating tangerines as food shouldn't throw off your gout prevention or cause problems. If you're using concentrated tangerine peel extracts or notice gout flaring up, 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.

  • AHigh-quality meta-analysis (quantitative systematic review).
  • BCase-control study.
  • CConsensus.

From our pharmacist’s overview on the Colchicine page

“Colchicine, the gout and pericarditis medicine sold as Colcrys and Mitigare, has one of the smallest gaps between a helpful dose and a harmful one of any drug I dispense, so its 146 supplement interactions deserve genuine respect. Most of them work the same way, blocking or speeding up the enzyme and transporter (CYP3A4 and P-glycoprot…”

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.

About Colchicine

What Is Colchicine Used For?

Brand names: Colchicine, Colsalide Improved, Mitigare, Colcrys, Gloperba, Lodoco

Colchicine tablets and capsules are used to prevent gout flares in adults, and colchicine tablets are also used to treat acute gout flares when taken at the first sign of a flare. Colchicine tablets are additionally approved for familial Mediterranean fever (FMF) — a hereditary inflammatory condition — in adults and children 4 years and older.

Lodoco (colchicine tablet) is specifically indicated to reduce the risk of heart attack, stroke, coronary revascularization, and cardiovascular death in adults with established atherosclerotic disease or multiple cardiovascular risk factors. Colchicine is not a pain reliever and should not be used for pain from other causes.
