Drug & supplement interaction

Slippery Elm + Insulin Lispro Recombinant

Insulin Lispro Recombinant brand name: Humalog Kwikpen.

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 Insulin Lispro Recombinant 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 Insulin Lispro Recombinant 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.

Interaction report

Slippery Elm and Insulin Lispro Recombinant

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 Insulin Lispro Recombinant 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.

How we checked

Why No Interaction Is Listed for Insulin Lispro Recombinant

Interactions in our licensed database are recorded against drug classes, not just single drug names. Insulin Lispro Recombinant is filed under 2 classifications — including antidiabetes drugs. Slippery Elm has documented interactions with 1 drug class — the most serious being oral drugs (moderate) — and none of Insulin Lispro Recombinant’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 Slippery Elm and Insulin Lispro Recombinant 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.

  • A skin rash Additional detail

    Slippery Elm

    “Topically, slippery elm extracts can cause contact dermatitis. The pollen is an allergen (6). Contact dermatitis and urticaria have been reported after exposure to slippery elm or an oleoresin contained in the slippery elm bark.”

Effects for Insulin Lispro Recombinant come from the ADVERSE REACTIONS section of its FDA label; effects for Slippery Elm 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 Insulin Lispro Recombinant Products Have a Food Rule — Slippery Elm Should Not Break It

At least one FDA label for a product containing Insulin Lispro Recombinant says to take it with food. If you take Slippery Elm on an empty stomach out of habit, keep them separate — and take Insulin Lispro Recombinant with a meal where the label says to.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Insulin Lispro Recombinant 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 , 2.2 , 2.3 , 2.4 ) Subcutaneous injection ( 2.2 ): Administer HUMALOG ® U-100 or U-200 by subcutaneous injection into the abdominal wall, thigh, upper arm, or buttocks within 15 minutes before a meal or immediately after a meal.

From the Dosage and Administration section of the FDA label we read for Insulin Lispro Recombinant — 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.

Everything else you take

See Every Supplement That Interacts With Insulin Lispro Recombinant

This page covers Slippery Elm only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Insulin Lispro Recombinant page lists 242 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Chelation Therapy Products (major), Siberian Cocklebur (major), Acai (moderate), African Wild Potato (moderate) and Agaricus Mushroom (moderate).

By severity: 2 major · 211 moderate · 29 minor.

From our pharmacist’s overview on the Insulin Lispro Recombinant page

“Two of the 242 entries here rate major, and they are the place to start. Siberian cocklebur has caused severe hypoglycemia, and chelation products containing EDTA can drop blood glucose steeply while also interfering with the insulin itself, so neither belongs anywhere near insulin lispro (Humalog KwikPen).”

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 Insulin Lispro Recombinant Together: Common Questions

Is it safe to take Slippery Elm with Insulin Lispro Recombinant?
We do not list a known interaction between Slippery Elm and Insulin Lispro Recombinant. 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 Insulin Lispro Recombinant 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.
Should I take Slippery Elm and Insulin Lispro Recombinant at the same time of day?
At least one FDA label for a product containing Insulin Lispro Recombinant says to take it with food. If you take Slippery Elm on an empty stomach out of habit, keep them separate and take Insulin Lispro Recombinant with a meal where the label says to. Food instructions belong to the product rather than the ingredient — two Insulin Lispro Recombinant products can differ — so check the directions on your own box. This is about absorption, not an interaction.
How was the Slippery Elm and Insulin Lispro Recombinant combination checked?
Interactions in our licensed database are recorded against drug classes. Insulin Lispro Recombinant is filed under 2 classifications, and Slippery Elm has documented interactions with 1 drug class — none of Insulin Lispro Recombinant's classifications are among them. A medication can belong to classes beyond those recorded in our dataset, so this describes how the check was run rather than guaranteeing safety.
Does Slippery Elm interact with any other medications?
Yes. Slippery Elm has 2,022 documented drug interactions in our database — Insulin Lispro Recombinant is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
Does Insulin Lispro Recombinant interact with any supplements?
Yes. Insulin Lispro Recombinant has documented interactions with 242 supplements in our database — Slippery Elm is not one of them. The Insulin Lispro Recombinant interaction page linked on this page lists every one, ranked by severity.
