Drug & supplement interaction

Arum + Nusinersen Sodium

Nusinersen Sodium brand name: Spinraza.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Oct 4, 2026
The bottom line No known interaction

We found no known interaction between Arum and Nusinersen Sodium 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.

Interaction report

Arum and Nusinersen Sodium

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 Nusinersen Sodium and Arum 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.

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.

How we checked

Why No Interaction Is Listed for Nusinersen Sodium

Interactions in our licensed database are recorded against drug classes, not just single drug names. Nusinersen Sodium is filed under 2 classifications — anticoagulant/antiplatelet drugs, nephrotoxic drugs. Arum has documented interactions with 1 drug class — the most serious being iron (minor) — and none of Nusinersen Sodium’s classifications are among them.

Classification data comes from our licensed Natural Medicines dataset. A medication can belong to classes beyond those recorded there, so this describes how the check was run — it is not a safety guarantee.

No Interaction Found — But Data Suggests Arum and Nusinersen Sodium May Share a Side Effect

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.

  • Vomiting reported in 4.0% of FDA reports for Nusinersen Sodium Additional detail

    Arum

    “Orally, arum has been reported to cause burning of the oral mucous membranes, likely due to its oxalate crystal content. The immediate burning sensation caused by arum is thought to limit its oral intake, possibly reducing the likelihood for arum toxicity. Arum has also been reported to cause bloody vomiting, bloody diarrhea, and swelling of the tongue, lips, and palate in some people (18,32466).”

    Nusinersen Sodium

    Listed in the ADVERSE REACTIONS section of the FDA label for Nusinersen Sodium, and in voluntary FDA adverse-event reports. Read the label on DailyMed ›

Reported for Arum but not commonly for Nusinersen Sodium: diarrhea and swelling.

Effects for Nusinersen Sodium come from the ADVERSE REACTIONS section of its FDA label; effects for Arum come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 7,655 voluntary FDA FAERS reports for Nusinersen Sodium that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

From our pharmacist’s overview on the Nusinersen Sodium page

“Spinraza (nusinersen) is given by spinal injection to treat spinal muscular atrophy, and it carries its own warnings for low platelets and kidney stress, which makes the 208 supplements on this page worth real vigilance rather than a shrug. All but six of them, 202 ingredients, could raise bleeding risk by thinning the blood or dulling…”

About Arum

What is Arum?

Arum
  • Coughs and chest congestion
  • Sore throat
  • Promoting sweating (diaphoretic)
  • Skin and wart remedies (topical folk use)
  • Digestive complaints

Arum is a traditional European plant whose root has been used in folk medicine, but there is essentially no reliable human research to support any health benefit. The raw plant is toxic and irritating because of calcium oxalate crystals, so it should not be eaten or used casually. We do not recommend using Arum as a supplement, especially during pregnancy or breastfeeding.

Arum maculatum · Araceae · Root (tuber), and sometimes leaves · Dried root preparations, tinctures, and traditional folk remedies

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

Arum: dosing

There is no established or standardized safe dose for Arum. Because the plant is toxic and human research is lacking, no trustworthy dosing guidelines exist.We do not recommend taking Arum. If you encounter a product that contains it, do not use it without first checking with a pharmacist or doctor, and never prepare or eat the raw plant yourself.

Nusinersen Sodium is filed under 2 classifications, and Arum has documented interactions with 1 drug class — none of Nusinersen Sodium's classifications are among them.
