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) Aspirin, Caffeine, Dihydrocodeine Bitartrate is classified into the pharmacology categories it belongs to, (2) every supplement interaction documented against any of those categories is inherited by Aspirin, Caffeine, Dihydrocodeine Bitartrate, 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.

Aspirin, Caffeine, Dihydrocodeine Bitartrate sits in 18 interaction categories. Open any one to see what the group means:

Anticoagulant/Antiplatelet Drugs 202 ingredients

The highest-ranked right now: Beer, Grapefruit, Siberian Cocklebur.
Which Aspirin, Caffeine, Dihydrocodeine Bitartrate supplement interactions are the most serious?
The 17 major-rated combinations — led by Beer, Grapefruit, Siberian Cocklebur, Wine and 1,4-butanediol — 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 Aspirin, Caffeine, Dihydrocodeine Bitartrate?
That depends entirely on which supplement. The honest answer for Aspirin, Caffeine, Dihydrocodeine Bitartrate 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 Synalgos DC have the same supplement interactions as Aspirin, Caffeine, Dihydrocodeine Bitartrate?
Yes — Synalgos DC all contain Aspirin, Caffeine, Dihydrocodeine Bitartrate, 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 Aspirin, Caffeine, Dihydrocodeine Bitartrate deplete any vitamins or nutrients?
It might — Aspirin, Caffeine, Dihydrocodeine Bitartrate has 5 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 Aspirin, Caffeine, Dihydrocodeine Bitartrate nutrient depletion report for the specifics and what to discuss with your pharmacist.
What about Aspirin, Caffeine, Dihydrocodeine Bitartrate and my other medications?
This page covers Aspirin, Caffeine, Dihydrocodeine Bitartrate against supplements and herbal ingredients. Checking Aspirin, Caffeine, Dihydrocodeine Bitartrate against your other prescription or OTC medications is a different tool — our drug interaction checker covers that side.
