Shiitake Mushroom and Hydrocodone, Ibuprofen

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

Moderate

CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES

Why this applies to Hydrocodone, Ibuprofen

Hydrocodone, Ibuprofen falls under CYTOCHROME P450 2D6 (CYP2D6) SUBSTRATES — the group Shiitake Mushroom interacts with.

Theoretically, shiitake mushroom might decrease levels of drugs metabolized by CYP2D6.
In vitro studies suggest that the shiitake mushroom extract AHCC might induce the CYP2D6 enzyme. This effect 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 something interesting about Vicoprofen: the hydrocodone part is actually a prodrug. Your body uses an enzyme called CYP2D6 to turn it into a stronger painkiller (hydromorphone). The lab research on file suggests a shiitake extract called AHCC might speed up that same enzyme. If that happened in real life, your body could convert hydrocodone a bit faster, which in theory might mean shorter-lasting or slightly weaker pain relief. The ibuprofen side isn't really affected here.

I want to be honest with you though: this is only based on test-tube studies, not people, so it's mostly theoretical. Everyday culinary shiitake in your dinner is very unlikely to matter. If you're thinking about concentrated shiitake or AHCC capsules, just run it by your pharmacist or doctor first.

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