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, Chlorpheniramine, Phenylpropanolamine is classified into the pharmacology categories it belongs to, (2) every supplement interaction documented against any of those categories is inherited by Aspirin, Chlorpheniramine, Phenylpropanolamine, 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, Chlorpheniramine, Phenylpropanolamine sits in 17 interaction categories. Open any one to see what the group means:

Anticoagulant/Antiplatelet Drugs 202 ingredients

Blood-thinning medications. Supplements with their own effects on clotting or platelets can add up with these drugs and raise bleeding risk.

Aspirin, Chlorpheniramine, Phenylpropanolamine & Supplements: Common Questions

What supplements interact with Aspirin, Chlorpheniramine, Phenylpropanolamine?
In our interaction database, 372 supplement and herbal ingredients have an interaction with Aspirin, Chlorpheniramine, Phenylpropanolamine on file — 16 rated major, 308 moderate, and 48 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: Grapefruit, Siberian Cocklebur, Activated Charcoal.
Which Aspirin, Chlorpheniramine, Phenylpropanolamine supplement interactions are the most serious?
Focus on the major group: Grapefruit, Siberian Cocklebur, Activated Charcoal, Beer and Danshen, 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 Aspirin, Chlorpheniramine, Phenylpropanolamine?
That depends entirely on which supplement. The honest answer for Aspirin, Chlorpheniramine, Phenylpropanolamine 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 Alka-Seltzer Plus Cold have the same supplement interactions as Aspirin, Chlorpheniramine, Phenylpropanolamine?
Yes — Alka-Seltzer Plus Cold all contain Aspirin, Chlorpheniramine, Phenylpropanolamine, 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, Chlorpheniramine, Phenylpropanolamine deplete any vitamins or nutrients?
It might — Aspirin, Chlorpheniramine, Phenylpropanolamine has 4 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, Chlorpheniramine, Phenylpropanolamine nutrient depletion report for the specifics and what to discuss with your pharmacist.
What about Aspirin, Chlorpheniramine, Phenylpropanolamine and my other medications?
This page covers Aspirin, Chlorpheniramine, Phenylpropanolamine against supplements and herbal ingredients. Checking Aspirin, Chlorpheniramine, Phenylpropanolamine against your other prescription or OTC medications is a different tool — our drug interaction checker covers that side.
