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

Carteolol sits in 4 interaction categories. Open any one to see what the group means:

Antihypertensive Drugs 119 ingredients

Blood-pressure-lowering medications. Supplements that lower (or raise) blood pressure can amplify or fight these drugs.

119 of the supplement ingredients on this page reach Carteolol 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 Carteolol through this category.

Seizure Threshold Lowering Drugs 6 ingredients

Carteolol & Supplements: Common Questions

What supplements interact with Carteolol?
Our database currently documents 143 ingredients with a known Carteolol interaction (5 major, 118 moderate, 20 minor). The practical move: scan the major group first, then look up the exact supplements you take rather than reading all 143. The highest-ranked right now: American Hellebore, Tyramine, Activated Charcoal.
Which Carteolol supplement interactions are the most serious?
The 5 major-rated combinations — led by American Hellebore, Tyramine, Activated Charcoal, American Mistletoe and Indian Snakeroot — 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 Carteolol?
Plenty of supplements coexist fine with Carteolol; a shorter list does not. Rather than memorizing it, check the specific ingredients on your labels — the ranked list above covers every one we've checked, and multi-ingredient products can be checked label-by-label with our scanner. Try the label scanner or the interaction checker.
Do brands like Cartrol have the same supplement interactions as Carteolol?
Yes — Cartrol, Ocupress all contain Carteolol, 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 Carteolol deplete any vitamins or nutrients?
It might — Carteolol has 2 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 Carteolol nutrient depletion report for the specifics and what to discuss with your pharmacist.
What about Carteolol and my other medications?
This page covers Carteolol against supplements and herbal ingredients. Checking Carteolol against your other prescription or OTC medications is a different tool — our drug interaction checker covers that side. Head to the drug–drug interaction checker.
