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.

Alcohol is the clearest danger here. Beer and wine both carry a major rating with codeine phosphate and pseudoephedrine (Nucofed, Kg Fed), because alcohol deepens the sedation the codeine half already causes, and that effect is well documented in people. This medicine pairs an opioid cough suppressant with a stimulant decongestant, so supplements can go wrong in either direction, and the list warrants genuine care. Of the 176 ingredients on file, 11 rate major, and understanding those should come first.

The themes mirror the drug's two halves. Seventy-eight ingredients, including kava and GHB, pile onto the sedating side, which at its worst means dangerously slowed breathing. Another 44, from ephedra down to everyday caffeine in coffee, tea, and cocoa, push the stimulant side and can raise blood pressure. Activated charcoal is different, trapping the dose in the gut so less reaches you, so space the two well apart.

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) Codeine Phosphate, Pseudoephedrine is classified into the pharmacology categories it belongs to, (2) every supplement interaction documented against any of those categories is inherited by Codeine Phosphate, Pseudoephedrine, 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.

Codeine Phosphate, Pseudoephedrine sits in 9 interaction categories. Open any one to see what the group means:

Cns Depressants 78 ingredients

Central-nervous-system depressants. Sedating supplements can intensify drowsiness and slowed reactions when combined.

78 of the supplement ingredients on this page reach Codeine Phosphate, Pseudoephedrine through this category.

Cytochrome P450 2D6 (Cyp2D6) Substrates 60 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.

Codeine Phosphate, Pseudoephedrine & Supplements: Common Questions

What supplements interact with Codeine Phosphate, Pseudoephedrine?
In our interaction database, 176 supplement and herbal ingredients have an interaction with Codeine Phosphate, Pseudoephedrine on file — 11 rated major, 142 moderate, and 23 minor. That number sounds scarier than it is: severity matters far more than the count, which is why the list on this page is ranked instead of alphabetical. Start at the top. The highest-ranked right now: Beer, Wine, 1,4-butanediol.
Which Codeine Phosphate, Pseudoephedrine supplement interactions are the most serious?
Focus on the major group: Beer, Wine, 1,4-butanediol, Activated Charcoal and Ephedra, among others. A major rating means the combination can be clinically significant, not that harm is guaranteed — but it's exactly the kind of thing to run past your pharmacist before your next dose, not after. Jump to the ranked list.
Can I take vitamins or supplements while on Codeine Phosphate, Pseudoephedrine?
That depends entirely on which supplement. The honest answer for Codeine Phosphate, Pseudoephedrine is in the ranked list above — and if what you take is a combination product with a dozen ingredients, don't check them one by one: photograph the label with our scanner and we'll check the whole thing at once. Try the label scanner or the interaction checker.
Do brands like Nucofed have the same supplement interactions as Codeine Phosphate, Pseudoephedrine?
Yes — Nucofed, Kg Fed all contain Codeine Phosphate, Pseudoephedrine, 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.
What about Codeine Phosphate, Pseudoephedrine and my other medications?
This page covers Codeine Phosphate, Pseudoephedrine against supplements and herbal ingredients.
