Broccoli Sprout and Acetaminophen, Meperidine

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

Minor

CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES

Why this applies to Acetaminophen, Meperidine

Acetaminophen, Meperidine falls under CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES — the group Broccoli Sprout interacts with.

Theoretically, broccoli sprout might reduce levels and effects of drugs metabolized by CYP1A2.
Animal research shows that broccoli sprout extract can increase CYP1A2 gene expression. Also, pharmacokinetic research in humans shows that eating 500 grams of fresh broccoli daily for 6-12 days can increase CYP1A2 activity by 10% to 200%. Induction of CYP1A2 activity by broccoli is attributed to glucosinolate constituents, which are also found in broccoli sprout.
Severity Minor 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 the gist with your Demerol APAP (that's meperidine plus acetaminophen). Broccoli sprouts contain compounds that may gently speed up a liver enzyme called CYP1A2, which plays a small role in clearing these medicines. In theory, faster clearance could slightly lower drug levels, meaning a touch less pain relief from the meperidine side. Honestly, this is rated minor and is only theoretical, based on lab and food studies, not real reports of problems.

Eating broccoli sprouts as food is very unlikely to matter here. Concentrated sulforaphane supplements taken daily are more of an open question. You don't need to avoid your veggies, but if you're using high-dose supplements, just run it by your pharmacist or doctor first.

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

“Demerol APAP pairs meperidine, an opioid painkiller, with acetaminophen, and that combination earns real caution with the 250 supplement entries below. Ten carry a major rating, and most of the danger runs through a single theme: anything else that quiets the brain.”

About Broccoli Sprout

What is Broccoli Sprout?

  • Antioxidant support
  • Detoxification support
  • General heart health
  • Anti-inflammatory support
  • Digestive and gut health

Broccoli sprouts are young broccoli seedlings rich in a compound called sulforaphane, which is being studied for antioxidant, anti-inflammatory, and detoxification effects. Early research is promising for some uses, but high-quality human evidence is still limited, so they should be viewed as a healthy food rather than a proven treatment. As food they are generally safe, but talk to your pharmacist or doctor before using concentrated supplements, especially during pregnancy or breastfeeding.
