Diindolylmethane and Benzhydrocodone, Acetaminophen

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

Minor

CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES

Why this applies to Benzhydrocodone, Acetaminophen

Benzhydrocodone, Acetaminophen falls under CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES — the group Diindolylmethane interacts with.

Theoretically, diindolylmethane might lower serum levels of CYP1A2 substrates.
In vitro evidence suggests that diindolylmethane can induce CYP1A2. Theoretically, it might increase metabolism of CYP1A2 substrates and lower serum concentrations. This interaction has not been reported in humans.
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

Here's the gist for Apadaz (benzhydrocodone with acetaminophen) and DIM. In lab studies, DIM appears to speed up an enzyme called CYP1A2. The idea is that revving up that enzyme could clear certain medicines a little faster and lower their blood levels. The honest truth is this is theoretical, based only on test-tube and animal data, and it has never actually been reported in people.

Benzhydrocodone is a prodrug, meaning your body has to convert it into its active painkiller (hydrocodone), and that mainly runs through a different enzyme (CYP3A4 and CYP2D6), not CYP1A2. So I wouldn't expect a meaningful change in your pain relief or side effects. Still, if you notice your pain medicine working differently, check in with your pharmacist or doctor before adjusting anything.

About Diindolylmethane

What is Diindolylmethane?

Diindolylmethane
  • Estrogen/hormone balance
  • Acne and hormonal skin issues
  • Prostate health support
  • Cancer-risk reduction (unproven)
  • PMS and menopause symptoms
  • General 'detox' support

Diindolylmethane (DIM) is a compound made when your body digests cruciferous vegetables, and it is sold as a supplement mainly for hormone balance and cancer prevention. Although early lab studies look interesting, strong human evidence is lacking for most of these uses. Talk with your pharmacist or doctor before taking DIM, especially if you have a hormone-sensitive condition.

About Benzhydrocodone and Acetaminophen

What Is Benzhydrocodone and Acetaminophen Used For?

Brand name: Apadaz

Apadaz is indicated for the short-term management of acute pain — up to 14 days — that is severe enough to require an opioid and for which non-opioid treatments have not worked or are not expected to work. It combines benzhydrocodone (a prodrug that converts to the opioid hydrocodone) with acetaminophen.

Because of serious risks including addiction, abuse, and misuse, Apadaz is reserved for patients who have not tolerated or have not gotten adequate relief from alternative pain treatments. It should not be used for an extended period of time unless the pain remains severe enough to require an opioid and alternatives remain inadequate.
