Drug & supplement interaction

Devil's Club + Mirabegron

Mirabegron brand name: Myrbetriq.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Devil's Club and Mirabegron in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Devil's Club and Mirabegron

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Mirabegron and Devil's Club in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

Worth understanding: our licensed dataset holds no drug-interaction record for Devil's Club at all — not against Mirabegron, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

Devil's Club safety at a glance

Devil's Club overall Use caution Limited human safety data exist, so use cautiously and under professional guidance.
Pregnancy Avoid Not enough safety information is available, so it is best avoided during pregnancy.
Breastfeeding Avoid Safety has not been studied in nursing mothers, so avoid use while breastfeeding.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

What to actually watch for

No Interaction Found — But Data Suggests Devil's Club and Mirabegron May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do.

“Mirabegron (Myrbetriq) treats overactive bladder only if enough of the pill actually gets absorbed, and that is exactly where most of this list hits. Seventeen of the 20 supplements on file, mostly fibers, gums, and charcoals, can change how much of an oral drug your gut takes up.”

About Devil's Club

What is Devil's Club?

  • Blood sugar support
  • Respiratory and cold symptoms
  • Arthritis and joint pain
  • Digestive complaints
  • General tonic and wellness

Devil's Club is a thorny shrub from the Pacific Northwest of North America that has long been used in Indigenous traditional medicine, especially for blood sugar and respiratory complaints. Scientific evidence in humans is very limited, so its benefits are not proven. Talk to your pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

Oplopanax horridus · Araliaceae · Root bark, stem bark, and inner bark · Tea or decoction, tincture, capsules, dried bark, topical salves

An interaction check asks whether these two react with each other — it does not ask whether Devil's Club is a good idea for someone in your situation. Here is what our Devil's Club record says about it on its own.

Devil's Club: dosing

There is no established standard dose for Devil's Club. The right amount has not been determined in clinical studies, and product strength can vary widely between brands and forms (tea, tincture, or capsule).If you choose to use it, follow the directions on the product label and do not exceed the suggested amount.

Taking Devil's Club and Mirabegron Together: Common Questions

Is it safe to take Devil's Club with Mirabegron?

Do Devil's Club and Mirabegron have any of the same side effects?
Yes — our sources link each of them separately to 3 of the same effects. That is not an interaction: neither changes how your body handles the other.

Does Mirabegron interact with any supplements?
Yes. Mirabegron has documented interactions with 20 supplements in our database — Devil's Club is not one of them. The Mirabegron interaction page linked on this page lists every one, ranked by severity.
