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

We found no known interaction between Adrenal Extract 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.

Adrenal Extract 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 Adrenal Extract 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.

Worth understanding: our licensed dataset holds no drug-interaction record for Adrenal Extract at all — not against Salmeterol, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

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.

What Salmeterol’s Own FDA Label Lists

This is not an interaction — none of it involves Adrenal Extract. These are the most notable effects listed in the ADVERSE REACTIONS section of Salmeterol’s own FDA label, for the medication by itself. Knowing the drug’s own list makes it easier to work out the likely cause if something new turns up while you take both. 2 of them are worth acting on rather than waiting out — marked below.

  • Wheezing Worth acting on mentioned in 15.2% of FDA reports for Salmeterol
  • A higher chance of infection Worth acting on mentioned in 6.8% of FDA reports for Salmeterol
  • Cough mentioned in 7.3% of FDA reports for Salmeterol
  • A stuffy or runny nose
  • Sore throat
  • Muscle pain
  • Headache

From the ADVERSE REACTIONS section of the FDA label for Salmeterol. Read the label on DailyMed › Where a percentage is shown, it is the share of 107,431 voluntary FDA FAERS reports for Salmeterol that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it. Adrenal Extract’s licensed record lists no adverse effects our clinical vocabulary could match, so there is no Adrenal Extract side to compare — that is a limit of the record, not a statement that Adrenal Extract has no side effects.

How to take them

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

At least one FDA label for a product containing Salmeterol says to take it on an empty stomach. Most supplements — Adrenal Extract 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 Adrenal Extract 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. Read the label on DailyMed ›

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.

Overlapping uses

What Salmeterol Is Prescribed For, and What Adrenal Extract Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Salmeterol is a prescription medicine with approved uses on its FDA label. Adrenal Extract is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Salmeterol is prescribed for: 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.

Adrenal Extract has been studied for:

  • Asthma studied, not established Adrenal Extract has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    Adrenal Extract for asthma

    Although there has been interest in using oral adrenal extract for asthma, there is insufficient reliable information about the clinical effects of adrenal extract for this purpose.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Salmeterol on your own; if you are taking Adrenal Extract for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

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 Adrenal Extract

What is Adrenal Extract?

  • Fatigue and low energy
  • "Adrenal fatigue" support
  • Stress and burnout
  • Low energy after illness
  • General "adrenal support"

Adrenal extract is a glandular supplement made from the adrenal glands of animals, and it is marketed mainly for fatigue and so-called "adrenal fatigue." There is no good scientific evidence that it works, and "adrenal fatigue" is not a recognized medical diagnosis. Because of possible safety and contamination concerns, talk with your pharmacist or doctor before trying it.

Adrenal glands (cortex and/or whole gland) of cattle, pigs, or sheep · Capsules, tablets, and glandular powder extracts

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

Adrenal Extract: dosing

There is no established or standardized dose for adrenal extract. Products vary widely in their source, strength, and ingredients, so there is no reliable "correct" amount.If you choose to use it despite the limited evidence, follow the directions on the product label and do not take more than recommended. Choosing brands that use independent third-party testing may help with quality, but it does not guarantee that the product works.

Taking Adrenal Extract and Salmeterol Together: Common Questions

Is it safe to take Adrenal Extract with Salmeterol?
We do not list a known interaction between Adrenal Extract 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 Adrenal Extract 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 Adrenal Extract 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.
Are Adrenal Extract and Salmeterol used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for Adrenal Extract in each. That is a conversation for your prescriber, especially if Salmeterol is being adjusted to a target.
Does Salmeterol interact with any supplements?
Yes. Salmeterol has documented interactions with 141 supplements in our database — Adrenal Extract is not one of them. The Salmeterol interaction page linked on this page lists every one, ranked by severity.
