No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 20, 2026
The bottom line No known interaction

We found no known interaction between Myrrh and Salmeterol 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 label for Salmeterol states a food rule worth keeping to.

Myrrh and Salmeterol

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 Salmeterol and Myrrh 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.

How we checked

Why No Interaction Is Listed for Salmeterol

Interactions in our licensed database are recorded against drug classes, not just single drug names. Salmeterol is filed under 3 classifications — beta-adrenergic agonists, qt interval-prolonging drugs, cytochrome p450 3a4 (cyp3a4) substrates. Myrrh has documented interactions with 2 drug classes — the most serious being antidiabetes drugs (moderate) and warfarin (coumadin) (moderate) — and none of Salmeterol’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

What Myrrh Itself Has Been Linked To

This is not an interaction — nothing below involves Salmeterol. It is the side-effect record for Myrrh on its own, from the licensed Natural Medicines monograph. If something new turns up after you add Myrrh, this list is the first place to look.

  • Itching / Swelling Additional detail

    “Orally, myrrh has been reported to cause severe allergic skin reactions, with redness, swelling, and itching, in two case reports of individuals using oral traditional Chinese medicines containing myrrh.”

  • Stomach pain Additional detail

    “Severe lower abdominal pain has been reported in a pregnant woman drinking myrrh resin dissolved in 500 mL of water twice daily as prescribed by a traditional practitioner. This adverse effect resolved one day after discontinuing myrrh. The investigators suggest that this acute abdominal pain was related to myrrh's activity as a uterine stimulant.”

Everything above comes from the Natural Medicines adverse-effect record for Myrrh — expand a row for the licensed statement it rests on. We read the ADVERSE REACTIONS section of Salmeterol’s FDA label too, and the two lists don’t meaningfully overlap — which is why no Salmeterol column appears here.

How to take them

Some Salmeterol Products Have a Food Rule — Myrrh Should Not Break It

At least one FDA label for a product containing Salmeterol says to take it on an empty stomach. Most supplements — Myrrh included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Salmeterol on its own and move Myrrh to a meal later in the day.

This may not be true of your version. Food instructions belong to the product, not the ingredient: two Salmeterol products can carry different directions, and extended-release forms often differ from immediate-release ones. The label we read is quoted below — check the directions on your own box or bottle, or ask your pharmacist, for how to take the exact product you were given.

One inhalation of SEREVENT DISKUS at least 30 minutes before exercise has been shown to protect patients against EIB.

From the Dosage and Administration section of the FDA label we read for Salmeterol — where that label names a specific product, the instruction is that product's. See the Salmeterol drug page ›

A food rule is not an interaction — it is about how much of the medicine you absorb. The directions that came with your own product, and your pharmacist, outrank anything on this page.

From our pharmacist’s overview on the Salmeterol page

“Salmeterol (Serevent) is the long-acting inhaler taken twice daily for asthma or COPD, and its supplement list is one I would approach with real caution. Seven of the 141 ingredients on file rate major: grapefruit can raise salmeterol levels by blocking the enzyme that clears it, St.”

About Myrrh

What is Myrrh?

Myrrh
  • Mouth and gum irritation
  • Sore throat
  • Minor wound and skin care
  • Digestive upset
  • Antimicrobial/antiseptic uses

Myrrh is a fragrant gum resin from Commiphora trees that has long been used in mouthwashes, throat remedies, and skin care. Modern evidence for most of its uses is limited and comes mostly from laboratory or small studies, so it should be viewed as a traditional remedy rather than a proven treatment. Talk with your pharmacist or doctor before using it, and avoid it during pregnancy.

Commiphora myrrha · Burseraceae · Gum resin (and essential oil distilled from the resin) · Tincture, mouthwash/gargle, capsules, powder, essential oil, topical preparations, incense

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

Myrrh: dosing

There is no well-established standard dose of myrrh for any condition. Strengths vary widely between tinctures, mouthwashes, capsules, and essential oils.The safest approach is to follow the directions on the product label and not exceed them. Mouthwashes and gargles are usually diluted and not swallowed. Essential oil should never be swallowed and must be diluted before applying to the skin.

About Salmeterol Oral Inhalation

What Is Salmeterol Oral Inhalation Used For?

Brand name: Serevent

Serevent Diskus (salmeterol inhalation powder) is used for three main purposes: treating asthma in patients aged 4 and older alongside an inhaled corticosteroid (ICS), preventing exercise-induced bronchospasm (EIB) in patients aged 4 and older, and providing long-term maintenance treatment of bronchospasm associated with COPD — including chronic bronchitis and emphysema — in adults.

Important: Serevent Diskus is not a rescue inhaler. It will not relieve a sudden asthma or COPD attack. For asthma, it must always be used together with an inhaled corticosteroid — using it alone for asthma is contraindicated due to a serious risk of asthma-related death.

Taking Myrrh and Salmeterol Together: Common Questions

Is it safe to take Myrrh with Salmeterol?
We do not list a known interaction between Myrrh and Salmeterol. 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.
Should I take Myrrh and Salmeterol at the same time of day?
At least one FDA label for a product containing Salmeterol says to take it on an empty stomach, and supplements are usually taken with a meal — so taking them together at breakfast is the easy mistake. Where that applies, keep Salmeterol on its own and move Myrrh to a meal later in the day. Food instructions belong to the product rather than the ingredient, so check the directions on your own box. This is about absorption, not an interaction.
How was the Myrrh and Salmeterol combination checked?
Interactions in our licensed database are recorded against drug classes. Salmeterol is filed under 3 classifications, and Myrrh has documented interactions with 2 drug classes — none of Salmeterol'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 Myrrh interact with any other medications?
Yes. Myrrh has 88 documented drug interactions in our database — Salmeterol 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 Salmeterol interact with any supplements?
Yes. Salmeterol has documented interactions with 141 supplements in our database — Myrrh is not one of them. The Salmeterol interaction page linked on this page lists every one, ranked by severity.
