What is this?
The interaction data in the HelloPharmacist supplement database is licensed from Natural Medicines Pro by TRC Healthcare (Therapeutic Research). HelloPharmacist pharmacists often add our own analysis and context on top of that licensed data — such as this Bottom Line summary and the notes on individual interaction pages — and any such commentary is noted as ours.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. Seventy-eight of these ingredients add to sedation, with alcohol (beer and wine are both rated major) and kava the clearest examples, and at the extreme the pairing can suppress breathing, the harm opioids are known for.
Meperidine can also trigger serotonin syndrome, and 20 ingredients add to that risk. Most of the 199 moderate entries change how liver enzymes handle the drug, while 41 rate minor. A few, activated charcoal among them, soak up oral doses and should be taken well apart. And because every tablet contains acetaminophen, the 38 ingredients that can stress the liver deserve a hard look, especially if you take this medicine daily.

Full Eleuthero + Acetaminophen, Meperidine answerWhat Severity, Likelihood & Evidence Mean
Severity — How Serious It Can Be
- Major. Clinically significant; generally best avoided, or used only under direct professional supervision.
- Moderate. May need monitoring, a dose adjustment, or separating the times you take each one.
- Minor. Generally not clinically significant, but still worth noting and mentioning to your pharmacist.
- No known interaction. Checked against our sources with nothing documented — not the same as proven safety.
Likelihood — How Well It’s Documented
- Likely. Well-controlled human studies have demonstrated the likely existence of this interaction
- Probable. 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.
- Possible. 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
- Unlikely. Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Where This Data Comes From
- Interaction records are evidence-graded and sourced from the Natural Medicines database (TRC Healthcare), the same reference used by pharmacists and hospitals.
- Each entry links to a full report with the clinical detail, likelihood, evidence level, and citations for that exact combination.
- Content is reviewed by licensed HelloPharmacist pharmacists — see our data sources and editorial standards.
How Does Our Interaction Checker Work?
Behind every verdict on this page is a category system. Our source database doesn’t document supplement interactions drug-by-drug — it documents them against groups of medications that behave the same way (for example, “drugs processed by the CYP3A4 liver enzyme” or “blood-thinning medications”).
So the check works in three steps: (1) Acetaminophen, Meperidine is classified into the pharmacology categories it belongs to, (2) every supplement interaction documented against any of those categories is inherited by Acetaminophen, Meperidine, and (3) each ingredient keeps its own severity, likelihood, and evidence grades from the underlying record. That’s why one supplement can carry several records for one drug — it may interact through more than one category.
Acetaminophen, Meperidine sits in 15 interaction categories. Open any one to see what the group means:
Cytochrome P450 1A2 (Cyp1A2) Substrates 79 ingredients
A drug-metabolism group: these medications are processed by the named liver enzyme (a cytochrome P450). Supplements that speed this enzyme up or slow it down can lower or raise the medication's levels in your body.
79 of the supplement ingredients on this page reach Acetaminophen, Meperidine through this category.
Cns Depressants 78 ingredients
Central-nervous-system depressants. Sedating supplements can intensify drowsiness and slowed reactions when combined.
