Schizonepeta 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 Schizonepeta interacts with.

Animal research suggests that schizonepetin, a monoterpene constituent of schizonepeta, induces cytochrome P450 (CYP) 3A4. Theoretically, schizonepeta might decrease the effects of CYP3A4 substrates.
Some substrates of CYP3A4 include lovastatin (Mevacor), ketoconazole (Nizoral), itraconazole (Sporanox), fexofenadine (Allegra), triazolam (Halcion), and numerous others.
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 colchicine and Schizonepeta. Your body clears colchicine partly through a liver enzyme called CYP3A4. Animal studies hint that a compound in Schizonepeta may speed that enzyme up. In theory, a faster enzyme could clear colchicine a bit quicker, which might leave you with less protection against gout flares or, for those using it for familial Mediterranean fever, less control of symptoms.

I want to be honest about the strength here: this is based only on lab and animal work, not real people, so it's a possibility rather than a proven problem. Colchicine has a narrow safety window, though, so I'd rather you not gamble. Please run it by your pharmacist or doctor before combining them, and let them know if your gout symptoms change.

  • 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).

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 Schizonepeta

What is Schizonepeta?

  • Common cold and early-stage fever
  • Itchy skin rashes and hives
  • Sore throat
  • Headache
  • Measles and other skin eruptions (traditional use)

Schizonepeta is a mint-family herb long used in traditional Chinese medicine, usually as part of combination formulas for colds, fevers, and itchy skin conditions. Modern human evidence is very limited, so its benefits are not well proven. Talk to a pharmacist or doctor before using it, especially if you are pregnant, breastfeeding, or taking other medicines.

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.
