Nutmeg and Umeclidinium Bromide

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

Moderate

ANTICHOLINERGIC DRUGS

Why this applies to Umeclidinium Bromide

Umeclidinium Bromide falls under ANTICHOLINERGIC DRUGS — the group Nutmeg interacts with.

Theoretically, concomitant use of nutmeg and anticholinergic drugs might decrease the effectiveness of either agent.
Animal research suggests that nutmeg extract can inhibit acetylcholinesterase and might increase acetylcholine levels.
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 the simple idea with Incruse Ellipta (umeclidinium). Your inhaler works by blocking acetylcholine in the airways, which relaxes the muscles and helps you breathe easier. Nutmeg, at least in animal studies, may do the opposite by raising acetylcholine levels. In theory, that could nudge against what your inhaler is trying to do and make it a bit less effective, meaning your COPD symptoms like wheezing or shortness of breath might not be as well controlled.

The reassuring part: this concern comes only from lab and animal research, not from people, so it's a theoretical worry. Normal cooking amounts of nutmeg are very unlikely to cause any trouble. Large "medicinal" doses are a different story and should be avoided anyway. If you take concentrated nutmeg supplements, just check in with your pharmacist or doctor first.

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 Nutmeg

What is Nutmeg?

Nutmeg
  • Digestive upset
  • Diarrhea
  • Sleep and relaxation
  • Pain and inflammation
  • Flavoring spice

Nutmeg is a popular cooking spice that has long been used in traditional medicine for digestion and other complaints, but there is little solid human research to support its medicinal use. In normal cooking amounts it is generally safe, but larger "medicinal" doses can cause serious poisoning, so it should never be taken in high amounts.

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.
