Soy and Hydrocodone, Ibuprofen

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

Minor

CYTOCHROME P450 2C9 (CYP2C9) SUBSTRATES

Why this applies to Hydrocodone, Ibuprofen

Hydrocodone, Ibuprofen falls under CYTOCHROME P450 2C9 (CYP2C9) SUBSTRATES — the group Soy interacts with.

Soy might modestly induce CYP2C9 enzymes. However, this effect does not seem to be clinically significant.
In vitro research suggests that an unhydrolyzed soy extract might induce CYP2C9. However, the significance of this interaction is likely minimal. In healthy females taking a specific extract of soy (Genistein Soy Complex, Source Naturals), blood levels of losartan, a CYP2C9 substrate, were not significantly affected.
Severity Minor Likelihood Unlikely Evidence D

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

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Vicoprofen pairs hydrocodone (for pain) with ibuprofen, and it's the ibuprofen part that gets handled by the CYP2C9 enzyme. The thought here is that soy might gently nudge that enzyme to work a little faster, which in theory could clear ibuprofen slightly quicker. If that happened, you might get a touch less anti-inflammatory benefit from the ibuprofen side of the combo.

Honestly, though, I wouldn't lose sleep over this one. The evidence is only lab-based, and a human study with a real soy supplement showed no meaningful change in a similar CYP2C9 drug. Regular soy foods almost certainly won't matter. If you take concentrated soy isoflavone supplements, just mention it to your pharmacist so they can double-check.

The biggest patterns are bleeding and sedation: more than 200 of these ingredients can add to ibu…”

About Soy

What is Soy?

  • Menopause symptoms (hot flashes)
  • Heart and cholesterol health
  • Bone health
  • Plant-based protein source
  • General nutrition

Soy is a nutritious bean that is a staple food and a popular source of plant protein and isoflavones. Eating soy foods as part of a balanced diet is generally considered safe for most people, and there is moderate evidence it may modestly help cholesterol and some menopause symptoms, though results vary. Talk with your pharmacist or doctor before using concentrated soy isoflavone supplements, especially if you have a history of hormone-sensitive conditions.
