Vitamin E and Colchicine

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Colchicine

Colchicine falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Vitamin E interacts with.

Theoretically, vitamin E might induce metabolism of CYP3A4, possibly reducing the levels CYP3A4 substrates.
Vitamin E appears to bind with the nuclear receptor, pregnane X receptor (PXR), which results in increased expression of CYP3A4. Although the clinical significance of this is not known, use caution when considering concomitant use of vitamin E and other drugs affected by these enzymes.
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 gist for your gout medicine. Your body clears colchicine partly through a liver enzyme called CYP3A4. The thinking on file is that high-dose vitamin E might gently speed up that enzyme, which could nudge colchicine levels down a bit. In plain terms, that might make colchicine a little less effective at preventing or calming a gout flare.

I want to be honest about how soft this is: it's a theoretical concern based on how vitamin E behaves in lab studies, not something proven in real patients. Normal dietary vitamin E almost certainly won't matter. If you're taking high-dose supplements, just give your pharmacist or doctor a heads-up so they can keep an eye on how well your colchicine is working.

Major

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

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 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 Vitamin E

What is Vitamin E?

Vitamin E

  • Eye health (age-related conditions)
  • Immune support

Vitamin E is an essential fat-soluble vitamin and antioxidant that most people get in adequate amounts from a normal diet.

Talk to your pharmacist or doctor before taking high doses.

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.
