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.For anyone carrying an epinephrine injection like Twinject for severe allergic reactions, the supplement interaction list is remarkably short. Just one ingredient is on file, butcher's broom, and it rates moderate. The concern is that butcher's broom appears to stimulate the same alpha-adrenergic pathways epinephrine uses, so the two together could push effects such as elevated blood pressure and a pounding heart further than the drug alone would.
The evidence here is theoretical, drawn from animal and lab studies rather than documented human cases, so this is a watch-and-know situation rather than a red flag. One thing matters above all else with this medication: in an actual emergency, use your epinephrine without hesitation, whatever supplements you take. If butcher's broom is part of your regular regimen, that is worth a conversation with your pharmacist on an ordinary day, not in a crisis.

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) Epinephrine Injection is classified into the pharmacology categories it belongs to, (2) every supplement interaction documented against any of those categories is inherited by Epinephrine Injection, 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.
Epinephrine Injection sits in 1 interaction category. Open any one to see what the group means:
Alpha-Adrenergic Agonists 1 ingredient
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.
1 of the supplement ingredient on this page reaches Epinephrine Injection through this category.

Epinephrine Injection & Supplements: Common Questions
What supplements interact with Epinephrine Injection?
More than you might expect — 1 in total, though they are far from equal: 0 are rated major, 1 moderate, and 0 minor. The ranked list on this page puts the ones that genuinely matter first, and every entry opens a full report on that exact pair. The highest-ranked right now: Butcher's Broom.
Which Epinephrine Injection supplement interactions are the most serious?
None of the Epinephrine Injection supplement interactions on file are currently rated major. The most significant are the 1 moderate-rated ones — combinations that may need monitoring, a dose adjustment, or separated timing. Still worth a quick look through the ranked list for anything you take daily. Jump to the ranked list.
Can I take vitamins or supplements while on Epinephrine Injection?
Usually yes — most people on Epinephrine Injection can take most supplements. The catch is the exceptions, and they aren't always the exotic ones (St. John's Wort trips up more prescriptions than almost anything sold next to it). Look up each ingredient you actually take in the list above, and treat "no known interaction" as a green-ish light, not a guarantee. Try the label scanner or the interaction checker.
Do brands like Twinject have the same supplement interactions as Epinephrine Injection?
Yes — Twinject all contain Epinephrine Injection, 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.
