Karaya Gum and Umeclidinium Bromide

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

Minor

ORAL DRUGS

Why this applies to Umeclidinium Bromide

Umeclidinium Bromide falls under ORAL DRUGS — the group Karaya Gum interacts with.

Co-administration of oral drugs with bulk forming laxatives such as karaya gum may decrease, increase, or have no effect on the absorption of drugs. To avoid changes in absorption, take karaya gum 30-60 minutes after oral medications.
Severity Minor 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 interaction we have on file talks about karaya gum, a bulk-forming fiber, possibly tugging on how oral medicines get absorbed in your gut. But Incruse Ellipta (umeclidinium) isn't swallowed at all. You breathe it straight into your lungs, so it skips your digestive tract almost entirely. That means a fiber laxative working inside your bowel has very little chance to change how this inhaler does its job.

This concern is theoretical and based on how fiber behaves with pills, not real-world reports with inhalers. Keep using your inhaler as directed, and if you ever have questions about timing your supplements, your pharmacist is happy to help.

From our pharmacist’s overview on the Umeclidinium Bromide page

“Umeclidinium bromide (Incruse Ellipta) keeps COPD airways open by blocking acetylcholine, and that mechanism is exactly where most of this list presses. Roughly two thirds of the flagged supplements act on the same pathway, either stacking anticholinergic side effects such as dry mouth and constipation, or working against the drug and…”

About Karaya Gum

What is Karaya Gum?

Karaya Gum
  • Constipation (bulk-forming laxative)
  • Appetite and weight management (bulking agent)
  • Dental adhesive/denture fixative
  • Skin barrier for ostomy appliances
  • Food thickening and stabilizing

Karaya gum is a natural plant gum from the Sterculia tree that is mostly used as a bulk-forming laxative and as a thickener or adhesive in food, dental, and ostomy products. As a fiber-type laxative it may help with occasional constipation, but high-quality evidence is limited, and it should be taken with plenty of water to avoid choking or blockage. Talk to your pharmacist or doctor before using it, especially if you have swallowing problems or bowel conditions.

About Umeclidinium Oral Inhalation

What Is Umeclidinium Oral Inhalation Used For?

Brand name: Incruse Ellipta

Umeclidinium Ellipta and Umeclidinium ELLIPTA (generic) are indicated for the maintenance treatment of COPD (chronic obstructive pulmonary disease) in adults. This means it is used every day on a regular schedule to help keep airways open and reduce COPD symptoms over time.

This medication is not a rescue inhaler. It will not treat a sudden flare-up or acute bronchospasm. A separate short-acting inhaler is needed for those situations.
