Hawthorn + Umeclidinium Bromide

Umeclidinium Bromide brand name: Incruse Ellipta.

No Known Interaction

Medically reviewed by Dr. Brian Staiger, PharmD, BCPS · Updated July 2026 · Pair last verified Sep 20, 2026

The bottom line No known interaction

We found no known interaction between Hawthorn and Umeclidinium Bromide 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

Hawthorn and Umeclidinium Bromide

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 Umeclidinium Bromide and Hawthorn 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.

Hawthorn overall Use caution Generally well tolerated in studies, but heart conditions need medical supervision.

How we checked

Why No Interaction Is Listed for Umeclidinium Bromide

Interactions in our licensed database are recorded against drug classes, not just single drug names. Umeclidinium Bromide is filed under 2 classifications — anticholinergic drugs, oral drugs. Hawthorn has documented interactions with 6 drug classes — the most serious being nitrates (major), phosphodiesterase-5 inhibitors (major) and anticoagulant/antiplatelet drugs (moderate) — and none of Umeclidinium Bromide’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.

Keep it in perspective

What to actually watch for

No Interaction Found — But Data Suggests Hawthorn and Umeclidinium Bromide May Share Several of the Same Side Effects

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. One of them is worth acting on rather than waiting out — marked below.

Reported for Hawthorn but not commonly for Umeclidinium Bromide: diarrhea, heart failure, stomach upset and an irregular heartbeat.

Effects for Umeclidinium Bromide come from the ADVERSE REACTIONS section of its FDA label; effects for Hawthorn come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 54,899 voluntary FDA FAERS reports for Umeclidinium Bromide that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

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 Hawthorn

What is Hawthorn?

Heart failure symptoms
High blood pressure
Chest pain (angina)
Irregular heartbeat
Digestive upset
Anxiety

Hawthorn is a plant traditionally used for heart-related complaints, and some studies suggest it may modestly help symptoms of mild heart failure when added to standard care. However, the evidence is mixed and it should never replace prescribed heart medicines. Always talk to your pharmacist or doctor before using hawthorn, especially if you have a heart condition.

Crataegus monogyna · Rosaceae · Leaves, flowers, and berries (fruit) · Capsules, tablets, standardized extracts, liquid tinctures, teas

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

Hawthorn: dosing

There is no single standard dose of hawthorn that fits everyone. This is especially important if you take heart or blood pressure medicines or have any chronic health condition. Do not assume that more is better.

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.

Most-Reported Side Effects for Umeclidinium Bromide

From FAERS, the FDA’s public side-effect reporting system (57,130 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Dyspnea 7,923 reports

Wrong technique in device usage process 4,830 reports

Product complaint 4,069 reports

Cough 3,863 reports

Pneumonia 2,698 reports

Taking Hawthorn and Umeclidinium Bromide Together: Common Questions

Is it safe to take Hawthorn with Umeclidinium Bromide?

We do not list a known interaction between Hawthorn and Umeclidinium Bromide. 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 Hawthorn and Umeclidinium Bromide have any of the same side effects?

Yes — our sources link each of them separately to 2 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.

How was the Hawthorn and Umeclidinium Bromide combination checked?

Interactions in our licensed database are recorded against drug classes. Umeclidinium Bromide is filed under 2 classifications, and Hawthorn has documented interactions with 6 drug classes — none of Umeclidinium Bromide'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 Hawthorn interact with any other medications?

Yes. Hawthorn has 191 documented drug interactions in our database — Umeclidinium Bromide 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 Umeclidinium Bromide interact with any supplements?

Yes. Umeclidinium Bromide has documented interactions with 46 supplements in our database — Hawthorn is not one of them. The Umeclidinium Bromide interaction page linked on this page lists every one, ranked by severity.
