Drug & supplement interaction

Progesterone + Salmeterol

Salmeterol brand name: Serevent.

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 Progesterone 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, and 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

Progesterone 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 Progesterone 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. Progesterone has documented interactions with 2 drug classes — the most serious being estrogens (moderate) and paclitaxel (abraxane, onxol) (minor) — 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.

Keep it in perspective

No Interaction Found — But Data Suggests Progesterone and Salmeterol 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.

  • Headache Additional detail

    Progesterone

    “Orally, progesterone can cause fatigue, drowsiness or insomnia, and headache. Topically, progesterone can cause headache. In one case report, a 37-year-old male crushed oral contraceptive pills containing progesterone and estrogen, mixed with water, and applied the mixture to the scalp twice daily for 3 months in an effort to stimulate hair growth. The patient developed a cerebral venous sinus thrombosis.”

    Salmeterol

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

Reported for Progesterone but not commonly for Salmeterol: blood clots, stomach upset, breast tenderness and swelling.

Effects for Salmeterol come from the ADVERSE REACTIONS section of its FDA label; effects for Progesterone come from the Natural Medicines adverse-effect record, quoted above. 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. Wording is matched across sources by our own clinical vocabulary, so treat this as a prompt to pay attention, not a diagnosis.

Progesterone in Pregnancy & Breastfeeding

Pregnancy Likely Unsafe

When used orally, intramuscularly, intravaginally, or transdermally for purposes other than medically supervised adjunctive treatment for infertility. There is insufficient reliable information available about the safety of any form of supplemental or non-prescription bioidentical progesterone products. Some research has shown that there are large variations in progesterone concentrations in non-prescription progesterone products.

How to take them

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

At least one FDA label for a product containing Salmeterol says to take it on an empty stomach. Most supplements — Progesterone 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 Progesterone 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.

About Progesterone

What is Progesterone?

  • Hormone replacement therapy
  • Supporting fertility and early pregnancy (under medical care)
  • Irregular or absent menstrual periods
  • Menopause-related symptoms (with estrogen)
  • Symptoms some attribute to low progesterone

Progesterone is a natural hormone, and prescription forms are used for fertility support, menstrual problems, and hormone therapy. Over-the-counter "natural" progesterone creams are not well standardized and their benefits are unproven, so any use of progesterone should be guided by a doctor or pharmacist.

Hormone (made in the body; supplement versions are synthesized, often from plant sterols) · Oral capsules, vaginal gels/inserts/suppositories, topical creams, intramuscular injections

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

Progesterone: dosing

There is no single standard dose for progesterone, and the right amount depends heavily on the form, the medical reason, and the person. Prescription dosing is set by a doctor based on the specific condition being treated.For over-the-counter creams, products vary widely in how much hormone they contain, and a reliable, proven dose has not been established.

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 Progesterone and Salmeterol Together: Common Questions

Is it safe to take Progesterone with Salmeterol?
We do not list a known interaction between Progesterone 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.
Do Progesterone and Salmeterol 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.
Should I take Progesterone 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 Progesterone 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 Progesterone and Salmeterol combination checked?
Interactions in our licensed database are recorded against drug classes. Salmeterol is filed under 3 classifications, and Progesterone 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 Progesterone interact with any other medications?
Yes. Progesterone has 42 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 — Progesterone is not one of them. The Salmeterol interaction page linked on this page lists every one, ranked by severity.
