Drug & supplement interaction

Ipecac + 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 Ipecac 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

Ipecac 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 Ipecac 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. Ipecac has documented interactions with 1 drug class — the most serious being activated charcoal (major) — 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

No Interaction Found — But Data Suggests Ipecac 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.

  • A stuffy or runny nose Additional detail

    Ipecac

    “Orally, ipecac syrup can cause nausea, vomiting, diarrhea, GI irritation, dizziness, hypotension, dyspnea, and tachycardia. Rarely, it can also cause intracerebral hemorrhage, pneumomediastinum, retropneumoperitoneum, esophageal bleeding (3,6,11,13,15,18,56390,56440,56447,56448). Chronic use is associated with myopathies and death (6,18,56391,56412,56413,56414,56416,56421,56422,56424).”

    Salmeterol

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

Reported for Ipecac but not commonly for Salmeterol: an irregular heartbeat, heart failure, seizures and a fast or pounding heartbeat.

Effects for Salmeterol come from the ADVERSE REACTIONS section of its FDA label; effects for Ipecac 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.

How to take them

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

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

What is Ipecac?

  • Inducing vomiting after poisoning (historical)
  • Cough and chest congestion (expectorant)
  • Nausea and vomiting (homeopathic use)
  • Amebic dysentery (historical)

Ipecac comes from the root of a South American plant and was once widely used as syrup of ipecac to make people vomit after swallowing poison. Medical groups no longer recommend it for poisoning because it is not proven helpful and can be dangerous, and misuse has caused serious harm. There is no safe, established home use for ipecac today, and you should call Poison Control rather than reach for it.

Carapichea ipecacuanha · Rubiaceae · Dried root and rhizome · Syrup (syrup of ipecac), tincture, liquid extract, homeopathic preparations

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

Ipecac: dosing

There is no recommended over-the-counter dose for ipecac because it is no longer advised for home use. We will not provide dosing amounts here, since using ipecac on your own can be harmful.If you have a product on hand, do not use it for poisoning—instead, call your Poison Control center or emergency services right away, as they can give the safest, up-to-date advice.For any homeopathic ipecac product, follow the directions on the label, but be aware these products are not proven to work.

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 Ipecac and Salmeterol Together: Common Questions

Is it safe to take Ipecac with Salmeterol?
We do not list a known interaction between Ipecac 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 Ipecac 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 Ipecac 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 Ipecac 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 Ipecac and Salmeterol combination checked?
Interactions in our licensed database are recorded against drug classes. Salmeterol is filed under 3 classifications, and Ipecac has documented interactions with 1 drug class — 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 Ipecac interact with any other medications?
Yes. Ipecac has 2 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 — Ipecac is not one of them. The Salmeterol interaction page linked on this page lists every one, ranked by severity.
