Slippery Elm and Glucagon

Here is the interaction we found between these two, with the evidence behind it.

Moderate

ORAL DRUGS

Why this applies to Glucagon

Glucagon falls under ORAL DRUGS — the group Slippery Elm interacts with.

Theoretically, slippery elm may slow the absorption and reduce serum levels of oral drugs.
Slippery elm inner bark contains mucilage, which may interfere with the absorption of orally administered drugs.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's some good news that should put your mind at ease. The concern on file is that slippery elm's sticky mucilage can coat the gut and slow down how well oral medications get absorbed. But the glucagon you're asking about isn't a pill. Baqsimi is a nasal powder, and other glucagon products are given by injection. Either way, it bypasses your stomach and intestines entirely, so slippery elm's gel in your gut simply isn't in the picture.

On top of that, this interaction is only theoretical, based on how slippery elm behaves rather than real cases. Since glucagon is a rescue treatment for very low blood sugar, you never want anything getting in its way, but here that risk doesn't really apply. Still, it's always smart to run your full supplement list by your pharmacist.

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.
