Drug & supplement interaction

Devil's Club + Naloxegol

Naloxegol brand name: Movantik.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Devil's Club and Naloxegol 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 label for Naloxegol states a food rule worth keeping to, and 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 Naloxegol

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 Naloxegol 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 Naloxegol, 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.

What to actually watch for

No Interaction Found — But Data Suggests Devil's Club and Naloxegol 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.

    Naloxegol

    Listed in the ADVERSE REACTIONS section of the FDA label for Naloxegol. Read the label on DailyMed ›

Reported for Devil's Club but not commonly for Naloxegol: an allergic reaction and dizziness.

Effects for Naloxegol come from the ADVERSE REACTIONS section of its FDA label; effects for Devil's Club come from the Natural Medicines adverse-effect record, quoted above. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

How to take them

Some Naloxegol Products Have a Food Rule — Devil's Club Should Not Break It

At least one FDA label for a product containing Naloxegol says to take it on an empty stomach. Most supplements — Devil's Club included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Naloxegol on its own and move Devil's Club to a meal later in the day.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Naloxegol products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

(2.1) Take on an empty stomach at least 1 hour prior to the first meal of the day or 2 hours after the meal.

From the Dosage and Administration section of the FDA label we read for Naloxegol — where that label names a specific product, the instruction is that product's. Read the label on DailyMed ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

From our pharmacist’s overview on the Naloxegol page

“Naloxegol (Movantik) relieves the constipation that opioids cause, and this is a list that deserves real care before you add anything from it. Nearly all of the trouble traces to a single enzyme, CYP3A4, which the body relies on to clear naloxegol.”

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 Naloxegol Together: Common Questions

Is it safe to take Devil's Club with Naloxegol?
We do not list a known interaction between Devil's Club and Naloxegol. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Devil's Club and Naloxegol 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. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Should I take Devil's Club and Naloxegol at the same time of day?
At least one FDA label for a product containing Naloxegol says to take it on an empty stomach, and supplements are usually taken with a meal — so taking them together at breakfast is the easy mistake. Where that applies, keep Naloxegol on its own and move Devil's Club to a meal later in the day. Food instructions belong to the product rather than the ingredient, so check the directions on your own box. This is about absorption, not an interaction.
Does Naloxegol interact with any supplements?
Yes. Naloxegol has documented interactions with 138 supplements in our database — Devil's Club is not one of them. The Naloxegol interaction page linked on this page lists every one, ranked by severity.
