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.

Fever bark is the ingredient I would flag first for anyone scheduled to receive chloroprocaine (Nesacaine), a local anesthetic injected for epidurals and other numbing procedures. It holds the list's lone major rating because its constituent reserpine has been linked to unstable blood pressure and heart rhythm under anesthesia. That risk warrants real caution, and the other four entries, all rated moderate, circle the same concern of supplements changing how safely anesthesia works.

Cannabis and THC may change how much anesthetic the body needs, cowhage contains levodopa, which has caused irregular heartbeats with some anesthetics, and Datura wrightii slows breathing, an effect that can stack dangerously during a procedure. Since chloroprocaine is given by a clinician rather than taken at home, the useful step is telling your anesthesia team about every supplement you use well ahead of time, fever bark most of all.

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

Chloroprocaine sits in 1 interaction category. Open any one to see what the group means:

Anesthesia 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.

5 of the supplement ingredients on this page reach Chloroprocaine through this category.

Chloroprocaine & Supplements: Common Questions

What supplements interact with Chloroprocaine?
Our database currently documents 5 ingredients with a known Chloroprocaine interaction (1 major, 4 moderate, 0 minor). The practical move: scan the major group first, then look up the exact supplements you take rather than reading all 5. The highest-ranked right now: Fever Bark, Cannabis, Cowhage.
Which Chloroprocaine supplement interactions are the most serious?
Focus on the major group: Fever Bark. 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 Chloroprocaine?
Plenty of supplements coexist fine with Chloroprocaine; 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 Nesacaine have the same supplement interactions as Chloroprocaine?
Yes — Nesacaine, Nescaine-MPF, Clorotekal all contain Chloroprocaine, 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 Chloroprocaine and my other medications?
This page covers Chloroprocaine against supplements and herbal ingredients. Checking Chloroprocaine against your other prescription or OTC medications is a different tool — our drug interaction checker covers that side.
