HelloPharmacist Bottom Line
Our Pharmacist Explains
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.

Cangrelor (Kengreal) is an antiplatelet given by IV during heart procedures such as stenting, and I treat its supplement list with genuine care. All 202 ingredients on it touch blood clotting, and nearly every one adds to the bleeding risk cangrelor creates by design. The two rated major, danshen and piracetam, have shown real platelet-blocking activity in research, and even everyday herbs like basil sit among the 183 moderate entries.

The scenario here is unusual, since cangrelor is given briefly under close medical supervision rather than taken at home, so what matters most is what is already in your system when you arrive. Tell the cardiology team about every supplement you have used recently, and afterward report unusual bruising or bleeding promptly. Only 17 entries rate minor, which shows how uniformly this list leans one way.

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

Cangrelor sits in 1 interaction category. 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.

202 of the supplement ingredients on this page reach Cangrelor through this category.

Cangrelor & Supplements: Common Questions

What supplements interact with Cangrelor?
In our interaction database, 202 supplement and herbal ingredients have an interaction with Cangrelor on file — 2 rated major, 183 moderate, and 17 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: Danshen, Piracetam, Bridelia.
Which Cangrelor supplement interactions are the most serious?
The 2 major-rated combinations — led by Danshen and Piracetam — 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 Cangrelor?
That depends entirely on which supplement. The honest answer for Cangrelor 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 Kengreal have the same supplement interactions as Cangrelor?
Yes — Kengreal all contain Cangrelor, 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.
What about Cangrelor and my other medications?
