Drug & supplement interaction

Slippery Elm + Isatuximab-Irfc

Isatuximab-Irfc brand name: Sarclisa.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Slippery Elm and Isatuximab-Irfc 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

Slippery Elm and Isatuximab-Irfc

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 Isatuximab-Irfc and Slippery Elm 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.

Slippery Elm safety at a glance

Slippery Elm overall Use caution Generally well tolerated for short-term use, but high-quality safety data are limited.
Pregnancy Use caution Not enough reliable safety data; some sources caution against using it during pregnancy.
Breastfeeding Use caution There is too little information on safety while breastfeeding, so caution is advised.

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 Slippery Elm and Isatuximab-Irfc 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.

Overlapping uses

What Isatuximab-Irfc Is Prescribed For, and What Slippery Elm Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Isatuximab-Irfc is a prescription medicine with approved uses on its FDA label. Slippery Elm is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Isatuximab-Irfc is prescribed for: Isatuximab-irfc injection is used to treat multiple myeloma in adults. It is always given in combination with other cancer medicines — never alone. Sarclisa Escena (subcutaneous injection) is approved: in combination with pomalidomide and dexamethasone for patients who have received at least 1 prior treatment including lenalidomide and a proteasome inhibitor; in combination with carfilzomib and dexamethasone for patients with relapsed or refractory multiple myeloma after 1 to 3 prior treatments; and in combination with bortezomib, lenalidomide, and dexamethasone for newly diagnosed multiple myeloma in adults who are not eligible for a stem cell transplant. Intravenous isatuximab-irfc (Sarclisa) is also used for these same indications.

Slippery Elm has been studied for:

  • Cancer studied, not established Slippery Elm has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Slippery Elm for cancer

    Oral slippery elm has only been evaluated in combination with other ingredients; its effect when used alone is unclear.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Isatuximab-Irfc on your own; if you are taking Slippery Elm for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Slippery Elm

What is Slippery Elm?

Slippery Elm
  • Sore throat and cough
  • Heartburn and acid reflux
  • Digestive upset and IBS
  • Skin irritation (topical)
  • Constipation or diarrhea

Slippery elm is a traditional herbal remedy made from the inner bark of a North American elm tree, used mainly to soothe sore throats and irritated digestive tracts. Its mucilage can coat and calm mucous membranes, but solid human evidence for most uses is limited. It is generally considered low-risk for short-term use, but you should still check with your pharmacist or doctor first.

Ulmus rubra · Ulmaceae · Inner bark · Capsules, tablets, lozenges, powder, tea, throat lozenges, topical pastes

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

Slippery Elm: dosing

There is no official standardized dose for slippery elm. The right amount can vary depending on the form (lozenge, capsule, powder, or tea) and the product.The safest approach is to follow the directions on the product label. When using the powder or capsules, take them with a full glass of water.

Taking Slippery Elm and Isatuximab-Irfc Together: Common Questions

Is it safe to take Slippery Elm with Isatuximab-Irfc?
We do not list a known interaction between Slippery Elm and Isatuximab-Irfc. 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 Slippery Elm and Isatuximab-Irfc have any of the same side effects?
Yes — our sources link each of them separately to one 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.
Are Slippery Elm and Isatuximab-Irfc used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Slippery Elm in each. That is a conversation for your prescriber, especially if Isatuximab-Irfc is being adjusted to a target.
Does Slippery Elm interact with any other medications?
Yes. Slippery Elm has 2,022 documented drug interactions in our database — Isatuximab-Irfc is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
