HelloPharmacist Bottom Line
Our Pharmacist Explains
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.

A muscle relaxant, an opioid, and acetaminophen travel together in Parafon Forte C8 (acetaminophen, chlorzoxazone, codeine), and that combination demands genuine care before adding any supplement. Of the 246 ingredients on file, 78 pile sedation onto a formula that already contains two sedating drugs, and that group accounts for most of the ten major-rated entries. Alcohol leads the pack, with beer and wine both rated major on solid human evidence. Anything that deepens drowsiness here can also slow breathing.

Most of the 196 moderate entries change how the body clears one of the three drugs, nudging levels up or down, and 40 more are minor. A few, activated charcoal among them, blunt absorption and should be spaced well apart from a dose. The acetaminophen component carries a hazard of its own, since 38 of these ingredients stress the liver just as it can.

What 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, Chlorzoxazone, Codeine is classified into the pharmacology categories it belongs to, (2) every supplement interaction documented against any of those categories is inherited by Acetaminophen, Chlorzoxazone, Codeine, 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, Chlorzoxazone, Codeine sits in 15 interaction categories. Open any one to see what the group means:

Cytochrome P450 1A2 (Cyp1A2) Substrates 79 ingredients

Acetaminophen, Chlorzoxazone, Codeine & Supplements: Common Questions

What supplements interact with Acetaminophen, Chlorzoxazone, Codeine?
More than you might expect — 246 in total, though they are far from equal: 10 are rated major, 196 moderate, and 40 minor. The ranked list on this page puts the ones that genuinely matter first, and every entry opens a full report on that exact pair. The highest-ranked right now: Beer, Siberian Cocklebur, Wine.
Which Acetaminophen, Chlorzoxazone, Codeine supplement interactions are the most serious?
The 10 major-rated combinations — led by Beer, Siberian Cocklebur, Wine, 1,4-butanediol and Activated Charcoal — deserve real caution: these are the ones generally best avoided, or used only with your prescriber watching. If you take any of them today, don't panic and don't stop anything abruptly — call your pharmacist first. Jump to the ranked list.
Can I take vitamins or supplements while on Acetaminophen, Chlorzoxazone, Codeine?
Usually yes — most people on Acetaminophen, Chlorzoxazone, Codeine can take most supplements. The catch is the exceptions, and they aren't always the exotic ones (St. John's Wort trips up more prescriptions than almost anything sold next to it). Look up each ingredient you actually take in the list above, and treat "no known interaction" as a green-ish light, not a guarantee. Try the label scanner or the interaction checker.
Do brands like Parafon Forte C8 have the same supplement interactions as Acetaminophen, Chlorzoxazone, Codeine?
Yes — Parafon Forte C8, Acetazone Forte C8 all contain Acetaminophen, Chlorzoxazone, Codeine, so everything on this page applies to them equally. Interactions belong to the active drug, never to the brand on the box; the same is true of generics.
Where do these interaction ratings come from?
Every rating comes from the Natural Medicines database — the same evidence-graded reference pharmacists and hospitals use — and each interaction carries three separate grades: severity (how bad it can be), likelihood (how well it's documented in studies and case reports), and an evidence level. Our pharmacists review the content; we never let an AI decide an interaction. See how to read the ratings and our editorial policy.
Does Acetaminophen, Chlorzoxazone, Codeine deplete any vitamins or nutrients?
It might — Acetaminophen, Chlorzoxazone, Codeine has 2 reported nutrient-depletion associations in the research literature, which is a different question from interactions: instead of a supplement changing the drug, the drug may lower a nutrient over time. See the Acetaminophen, Chlorzoxazone, Codeine nutrient depletion report for the specifics and what to discuss with your pharmacist.
What about Acetaminophen, Chlorzoxazone, Codeine and my other medications?
This page covers Acetaminophen, Chlorzoxazone, Codeine against supplements and herbal ingredients. Checking Acetaminophen, Chlorzoxazone, Codeine against your other prescription or OTC medications is a different tool — our drug interaction checker covers that side.
