Drug & supplement interaction

Saffron + Umeclidinium Bromide

Umeclidinium Bromide brand name: Incruse Ellipta.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Saffron 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.

Saffron 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 Saffron 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.

Saffron safety at a glance

Saffron overall Use caution Likely safe in food amounts, but supplement doses should be used carefully and high doses can be toxic.
Pregnancy Likely Unsafe When used orally in amounts exceeding those commonly found in foods. Larger amounts of saffron have uterine stimulant and abortifacient effects; avoid using. Read the full pregnancy detail
Breastfeeding Use caution Not enough reliable safety information, so it is best to avoid supplement amounts.

Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

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. Saffron has documented interactions with 4 drug classes — the most serious being antidiabetes drugs (moderate), antihypertensive drugs (moderate) and caffeine (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.

What to actually watch for

No Interaction Found — But Data Suggests Saffron and Umeclidinium Bromide 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. One of them is worth acting on rather than waiting out — marked below.

  • Wheezing Worth acting on Additional detail

    “Allergy to oral saffron has been reported in clinical trials. Anaphylactic reactions can occur within minutes of eating food prepared with saffron. Occupational exposure to saffron has been associated with the development of rhinoconjunctivitis and allergy-induced asthma.”

    Umeclidinium Bromide

    Listed in the ADVERSE REACTIONS section of the FDA label for Umeclidinium Bromide. Read the label on DailyMed ›

Reported for Saffron but not commonly for Umeclidinium Bromide: loss of bladder control, constipation, a severe allergic reaction and drowsiness.

Effects for Umeclidinium Bromide come from the ADVERSE REACTIONS section of its FDA label; effects for Saffron 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 Saffron

What is Saffron?

Saffron
  • Depression and low mood
  • Anxiety
  • PMS symptoms
  • Memory and cognition
  • Eye health (age-related macular degeneration)

Saffron is a costly spice that has shown promise in early studies for mild-to-moderate depression and some mood and PMS symptoms, but most research uses small trials, so results are not definitive. It is generally well tolerated in food and small supplement amounts, but high doses can be harmful and it should be avoided in pregnancy. Talk to your pharmacist or doctor before using saffron supplements.

Crocus sativus · Iridaceae · Dried stigmas of the flower · Capsules, tablets, dried spice, extracts, tea

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

Saffron: dosing

There is no official, standardized dose of saffron for any health condition. Many supplement studies have used standardized extracts, but products vary widely in strength and quality.The best approach is to follow the directions on the product label and not exceed the recommended amount. Because high doses can be harmful, more is not better with saffron.

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.

Taking Saffron and Umeclidinium Bromide Together: Common Questions

Is it safe to take Saffron with Umeclidinium Bromide?
We do not list a known interaction between Saffron 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 Saffron and Umeclidinium Bromide 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.
How was the Saffron and Umeclidinium Bromide combination checked?
Interactions in our licensed database are recorded against drug classes. Umeclidinium Bromide is filed under 2 classifications, and Saffron has documented interactions with 4 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 Saffron interact with any other medications?
Yes. Saffron has 521 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 — Saffron is not one of them. The Umeclidinium Bromide interaction page linked on this page lists every one, ranked by severity.
