Cabbage and Acetaminophen, Hydrocodone

These two interact in 3 distinct ways. Each one is explained separately below.

Why Are There 3 Interactions?

Cabbage interacts with whole categories of medication. Acetaminophen, Hydrocodone falls into 3 of those categories, so it can interact with Cabbage in 3 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES

1 of 3

Why this applies to Acetaminophen, Hydrocodone

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

Theoretically, cabbage might decrease levels of drugs metabolized by CYP1A2.
Some animal research suggests that cabbage or its constituent indole-3-carbinol might increase drug metabolism and elimination by stimulating CYP1A2 activity.
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 explains PharmD, Clinical Pharmacist

Here's the short version: this combo is really more of a 'good to know' than a 'worry about it.' The idea is that cabbage (specifically a compound called indole-3-carbinol, which is concentrated in cruciferous veggies) might nudge a liver enzyme called CYP1A2 to work a little faster. In theory, speeding up that enzyme could clear certain medicines out a bit quicker. For your Norco or Vicodin, that could mean slightly less pain relief if it had any meaningful effect.

But honestly, the evidence here is very thin, based only on lab and animal studies, not people. Eating cabbage as a normal food is very unlikely to change how your pain medicine works. I'd only raise an eyebrow if you were taking concentrated supplements. If you're unsure, just check with your pharmacist.

GLUCURONIDATED DRUGS

2 of 3

Acetaminophen, Hydrocodone also falls under GLUCURONIDATED DRUGS.

Theoretically, cabbage might increase clearance and decrease the effects of drugs metabolized through glucuronide conjugation.
A small clinical study shows that daily consumption of cabbage and Brussels sprout decreases levels of some drugs metabolized through glucuronide conjugation.
Severity Moderate Likelihood Probable Evidence B

Interaction 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..

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

Here's the deal with Vicodin or Norco (which combine acetaminophen with hydrocodone) and cabbage. A big chunk of acetaminophen is cleared from your body through a process called glucuronidation. Some research suggests that eating cabbage and Brussels sprouts regularly can speed that process up, so your body may clear the acetaminophen a little faster. In plain terms, that could mean slightly weaker, shorter pain relief from the acetaminophen part of the combo.

Honestly, I wouldn't lose sleep over this one. The effect is modest, the evidence is limited, and normal cabbage on your dinner plate is unlikely to throw things off. If you eat large amounts daily or take concentrated cabbage supplements, mention it to your pharmacist or doctor so they can keep an eye on your pain control.

ACETAMINOPHEN (Tylenol, others)

3 of 3
Cabbage might increase clearance and reduce the effects of acetaminophen.
A small clinical study shows that daily consumption of cabbage and Brussels sprout decreases acetaminophen levels by as much as 16%, with some evidence suggesting that this effect is due to increased elimination through glucuronide conjugation.
Severity Moderate Likelihood Probable Evidence B

Interaction 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..

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

Here's what's going on with your Norco or Vicodin: that pill is really two medicines, hydrocodone for pain plus acetaminophen (Tylenol). The interaction on file is with the acetaminophen part. In one small study, eating cabbage and Brussels sprouts every day sped up how fast the body cleared acetaminophen, lowering its levels by about 16%. In plain terms, cabbage may make the Tylenol portion wear off a little quicker, so you could get slightly less pain and fever relief from it.

Honestly, this is a modest effect, and normal amounts of cabbage in your meals are unlikely to cause a real problem. It does not change the hydrocodone (opioid) side. If you eat large amounts regularly and notice your pain control slipping, just mention it to your pharmacist or doctor before changing anything.

From our pharmacist’s overview on the Acetaminophen, Hydrocodone page

“Someone taking hydrocodone with acetaminophen (Vicodin, Norco) for post-surgical or dental pain often reaches for a sleep aid, kava, or a glass of wine at night, and that is exactly where the risk sits. This combination calls for genuine vigilance.”

About Cabbage

What is Cabbage?

Cabbage
  • Breast engorgement during breastfeeding
  • Joint pain and swelling (topical)
  • Digestive and stomach upset
  • General nutrition and antioxidant support
  • Skin and minor inflammation (topical)

Cabbage is a nutritious, low-calorie vegetable that is safe to eat as food and is sometimes applied to the skin as a leaf wrap for breast engorgement or sore joints. Most medicinal claims are based on tradition or limited research, with the strongest (though still modest) evidence being for cooling cabbage leaves on engorged breasts. Talk to your pharmacist or doctor before using cabbage in large amounts or as a treatment.
