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.Rezira and P-V-Tussin pair hydrocodone, an opioid, with pseudoephedrine, a decongestant, so the 241 supplements here pull in two directions and I would handle this combination with real care. Most entries either deepen the opioid's sedation (78 ingredients are CNS depressants, alcohol included) or stack stimulant effects onto the pseudoephedrine, pushing blood pressure and heart rate up. Another large group changes how your body clears the hydrocodone; grapefruit can raise its level while St. John's wort can lower it.
Thirteen of the 241 rate major, and those deserve your attention before the rest. Anything sedating carries the most danger, because an opioid plus another depressant can slow your breathing, not just make you drowsy. On the stimulant side, even everyday caffeine lands among the 190 moderates, so if a supplement leaves you jittery or your heart racing on this medicine, treat that as a warning and not a quirk.

Moderate Possibly, but carefully — this moderate-rated combination may need monitoring, a dose adjustment, or separated timing. Theoretically, diosmin might inhibit the metabolism of CYP3A4 substrates.
Full Diosmin + Hydrocodone, Pseudoephedrine 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) Hydrocodone, Pseudoephedrine is classified into the pharmacology categories it belongs to, (2) every supplement interaction documented against any of those categories is inherited by Hydrocodone, 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.
Hydrocodone, Pseudoephedrine sits in 9 interaction categories. Open any one to see what the group means:
Cytochrome P450 3A4 (Cyp3A4) Substrates 121 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.
121 of the supplement ingredients on this page reach Hydrocodone, Pseudoephedrine through this category.
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 Hydrocodone, 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.
60 of the supplement ingredients on this page reach Hydrocodone, Pseudoephedrine through this category.
