Cabbage and Acetaminophen, Caffeine, Pyrilamine

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, Caffeine, Pyrilamine 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, Caffeine, Pyrilamine

Acetaminophen, Caffeine, Pyrilamine 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 deal with this combo. Of the three ingredients in Midol Max Strength, the caffeine is the one your body clears using an enzyme called CYP1A2. Some lab and animal studies hint that cabbage (specifically a compound called indole-3-carbinol) might speed up that enzyme, which could mean caffeine gets cleared a little faster. In plain terms, you might notice a touch less of caffeine's pep, but this is unlikely to be a big deal.

Honestly, this is a theoretical concern based only on animal data, not on people. Normal cabbage you eat with dinner almost certainly won't matter. If you're taking concentrated cabbage or indole-3-carbinol supplements regularly, just mention it to your pharmacist so they can keep an eye on things.

GLUCURONIDATED DRUGS

2 of 3

Acetaminophen, Caffeine, Pyrilamine 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 Midol Max Strength and cabbage. One of the ingredients, acetaminophen (Tylenol), is cleared from your body partly through a process called glucuronidation, basically your liver tagging it so it can be flushed out. There's some early research showing that eating cabbage and Brussels sprouts every day can speed up that tagging process, which could lower acetaminophen levels and make it work a little less well for your cramps or headache.

In real life, this is pretty mild. A normal serving of cabbage at dinner isn't going to throw off your Midol. The concern is more theoretical and would only matter with large, daily amounts. If you eat a lot of cruciferous veggies and feel your Midol isn't doing much, just check in with your pharmacist or doctor.

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

This product (Midol Max Strength) combines acetaminophen with caffeine and an antihistamine called pyrilamine. The piece that interacts with cabbage is the acetaminophen. Cabbage and other cruciferous veggies like Brussels sprouts can nudge your body to clear acetaminophen a little faster, mainly by speeding up how the liver attaches it to a sugar molecule (glucuronidation) so it leaves the body quicker. In one small study, acetaminophen levels dropped by about 16%.

In plain terms, your cramp and headache relief might feel slightly weaker or wear off a touch sooner. This is a modest effect, and normal amounts of cabbage in your meals are unlikely to be a big deal. If you eat a lot of cruciferous vegetables and feel your Midol isn't working as well, check with your pharmacist before changing anything.

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.
