Feverfew 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 Feverfew interacts with.

Theoretically, feverfew might increase levels of drugs metabolized by CYP3A4.
Laboratory research shows that feverfew might inhibit CYP3A4. So far, this interaction has not been reported in humans.
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 basic idea. Your body relies on an enzyme called CYP3A4 to help clear colchicine out of your system. In lab studies, feverfew appears to slow that enzyme down. If that happened in real life, colchicine could build up a bit more than expected, and that's worth paying attention to because colchicine has a fairly narrow safety window.

When colchicine levels climb, the usual warning signs are stomach related, things like nausea, diarrhea, cramping, and vomiting, sometimes followed by muscle weakness. The good news is that this interaction has only been seen in the lab so far, not in actual patients, so it's mostly theoretical. Still, I'd run it past your pharmacist or doctor before pairing them, just to be safe.

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 Feverfew

What is Feverfew?

Feverfew
  • Migraine prevention
  • Headache
  • Fever (traditional)
  • Arthritis and joint pain
  • Menstrual discomfort

Feverfew is a daisy-family herb best known for migraine prevention, where some studies suggest it may modestly lower how often migraines occur, though the evidence is mixed. It is generally well tolerated for short-term use in most adults but should be avoided during pregnancy and breastfeeding and by people allergic to ragweed and related plants. Talk to your pharmacist or doctor before starting it.

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.
