Eurycoma Longifolia 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 Eurycoma Longifolia 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.

Eurycoma Longifolia safety at a glance

Eurycoma Longifoli... overall Use caution Generally tolerated short-term in studies, but long-term safety and product quality are uncertain.
Pregnancy Avoid Not enough safety data and possible hormonal effects, so avoid during pregnancy.
Breastfeeding Avoid No reliable safety information, so it is best to avoid while breastfeeding.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

Pharmacist analysis

Although there is no known interaction in this case, Eurycoma longifolia, most commonly known as Tongkat Ali, does have some potential interactions that are important to be aware of.

For example, it may interact with the following:

  • CYTOCHROME P450 1A2 (CYP1A2) SUBSTRATES
  • CYTOCHROME P450 2C19 (CYP2C19) SUBSTRATES
  • CYTOCHROME P450 2A6 (CYP2A6) SUBSTRATES
  • Propranolol
  • Testosterone

Tongkat Ali has been reported to inhibit certain metabolizing enzymes in the liver (the ones mentioned above) and therefore, may increase the levels of substances metabolized by those enzymes. This could potentially affect the way these substances work or how long they stay in your system.

In regard to propranolol, some studies show that Tongkat Ali decreases how well propranolol is absorbed in the gut and could reduce its effects. It is not known if separating administration will prevent this interaction/

Lastly, testosterone, Tongkat Ali may theoretically further increase levels of testosterone, a hormone responsible for various functions in the body. You should be cautious combining the two.

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. Eurycoma Longifolia has documented interactions with 5 drug classes — the most serious being propranolol (inderal) (moderate), cytochrome p450 1a2 (cyp1a2) substrates (minor) and cytochrome p450 2a6 (cyp2a6) substrates (minor) — 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 Eurycoma Longifolia Itself Has Been Linked To

This is not an interaction — nothing below involves Umeclidinium Bromide. It is the side-effect record for Eurycoma Longifolia on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Eurycoma Longifolia, this list is the first place to look. One entry is worth acting on rather than waiting out — marked below.

  • Liver problems Worth acting on Additional detail

    “Some research in both humans and animals suggests that Eurycoma longifolia might increase testosterone levels. If testosterone levels are increased beyond the normal range, there is risk of testosterone-related side effects which could include acne, insulin resistance, hepatotoxicity, and others.”

We read the ADVERSE REACTIONS section of Umeclidinium Bromide’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Umeclidinium Bromide column appears here.

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…”

What is Eurycoma Longifolia?

Eurycoma Longifolia
  • Low testosterone or low libido in men
  • Male fertility support
  • Athletic performance and muscle strength

Eurycoma longifolia (tongkat ali) is a Southeast Asian herb most popular for supporting testosterone, libido, and male fertility, with some small human studies suggesting possible benefits.
