Full Polypodium Leucotomos + Guaifenesin, Hydrocodone 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.

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) Guaifenesin, Hydrocodone is classified into the pharmacology categories it belongs to, (2) every supplement interaction documented against any of those categories is inherited by Guaifenesin, Hydrocodone, 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.
Guaifenesin, Hydrocodone sits in 6 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 Guaifenesin, Hydrocodone 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 Guaifenesin, Hydrocodone 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 Guaifenesin, Hydrocodone through this category.
Oral Drugs 17 ingredients
A pharmacology grouping from our source database: medications in this group share a property that certain supplements are known to interact with, so an interaction documented for the group applies to every drug in it.
17 of the supplement ingredients on this page reach Guaifenesin, Hydrocodone through this category.
Seizure Threshold Lowering Drugs 6 ingredients
A pharmacology grouping from our source database: medications in this group share a property that certain supplements are known to interact with, so an interaction documented for the group applies to every drug in it.
6 of the supplement ingredients on this page reach Guaifenesin, Hydrocodone through this category.
Narcotic Drugs 5 ingredients
A pharmacology grouping from our source database: medications in this group share a property that certain supplements are known to interact with, so an interaction documented for the group applies to every drug in it.
