Drug & supplement interaction

Nutmeg + Montelukast Sodium

Montelukast Sodium brand name: Singulair.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Nutmeg and Montelukast Sodium 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 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

Nutmeg and Montelukast Sodium

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 Montelukast Sodium and Nutmeg 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 Montelukast Sodium

Interactions in our licensed database are recorded against drug classes, not just single drug names. Montelukast Sodium is filed under 2 classifications — cytochrome p450 2c9 (cyp2c9) substrates, oral drugs. Nutmeg has documented interactions with 5 drug classes — the most serious being anticholinergic drugs (moderate), cholinergic drugs (moderate) and cns depressants (moderate) — and none of Montelukast Sodium’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

What to actually watch for

No Interaction Found — But Data Suggests Nutmeg and Montelukast Sodium May Share Several of the Same Side Effects

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. 4 of them are worth acting on rather than waiting out — marked below.

Showing the 10 most notable of 15 shared effects — ranked by how unusual each one is, not just whether both lists mention it.

Reported for Nutmeg but not commonly for Montelukast Sodium: thoughts of self-harm, increased thirst, low sodium and low blood pressure.

Effects for Montelukast Sodium come from the ADVERSE REACTIONS section of its FDA label; effects for Nutmeg come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 121,067 voluntary FDA FAERS reports for Montelukast Sodium 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.

Special populations

Nutmeg in Pregnancy & Breastfeeding

Pregnancy Likely Safe

When used orally and appropriately in amounts commonly found in foods.

Pregnancy Possibly Unsafe

When used orally in medicinal amounts. Nutmeg might have abortifacient activity, and its safrole content might be mutagenic.

Lactation Likely Safe

When used orally and appropriately in amounts commonly found in foods. There is insufficient reliable information available about the safety of nutmeg when used in larger, medicinal amounts during lactation; avoid using.

See Every Supplement That Interacts With Montelukast Sodium

This page covers Nutmeg only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Montelukast Sodium page lists 81 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Adrafinil (moderate), African Wild Potato (moderate), Bacopa (moderate) and Berberine (moderate).

By severity: 1 major · 56 moderate · 24 minor.

From our pharmacist’s overview on the Montelukast Sodium page

“If you rely on montelukast (Singulair) for asthma or allergies, this list deserves genuine attention. The one major-rated concern is activated charcoal, which can soak up the medicine in your gut before it absorbs, leaving you with a weaker dose just when your airways need a steady one.”

About Nutmeg

What is Nutmeg?

Nutmeg
  • Digestive upset
  • Diarrhea
  • Sleep and relaxation
  • Pain and inflammation
  • Flavoring spice

Nutmeg is a popular cooking spice that has long been used in traditional medicine for digestion and other complaints, but there is little solid human research to support its medicinal use. In normal cooking amounts it is generally safe, but larger "medicinal" doses can cause serious poisoning, so it should never be taken in high amounts.

Myristica fragrans · Myristicaceae · Seed (nutmeg), seed covering (mace), and essential oil · Whole or ground spice, powder, capsules, essential oil

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

Nutmeg: dosing

There is no well-established medicinal dose for nutmeg, and no standardized supplement dose has been proven safe and effective for any health condition. As a spice, the small amounts used in cooking are considered safe.Because the line between a flavoring amount and a toxic amount is not very wide, you should not take large doses of nutmeg for health purposes.

About Montelukast

What Is Montelukast Used For?

Brand name: Singulair

Montelukast is used for the long-term prevention and treatment of asthma in children and adults, and for preventing breathing problems triggered by exercise (exercise-induced bronchoconstriction). It is also used to relieve symptoms of seasonal allergic rhinitis (hay fever) and perennial allergic rhinitis (year-round nasal allergies). The age ranges covered depend on the specific product form — tablets, chewable tablets, and oral granules are each approved for different age groups.

For allergic rhinitis, montelukast should be reserved for people who haven't responded well to other treatments, because its potential mental health risks may outweigh the benefits when nasal allergy symptoms are mild and other options work. It is not a rescue treatment for sudden asthma attacks — always keep a fast-acting inhaler on hand.

Most-Reported Side Effects for Montelukast Sodium

From FAERS, the FDA’s public side-effect reporting system (121,067 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Asthma 14,956 reports
Dyspnea 14,837 reports

Taking Nutmeg and Montelukast Sodium Together: Common Questions

Is it safe to take Nutmeg with Montelukast Sodium?
We do not list a known interaction between Nutmeg and Montelukast Sodium. 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 Nutmeg and Montelukast Sodium have any of the same side effects?
Yes — our sources link each of them separately to 10 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.
How was the Nutmeg and Montelukast Sodium combination checked?
Interactions in our licensed database are recorded against drug classes. Montelukast Sodium is filed under 2 classifications, and Nutmeg has documented interactions with 5 drug classes — none of Montelukast Sodium'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 Nutmeg interact with any other medications?
Yes. Nutmeg has 528 documented drug interactions in our database — Montelukast Sodium 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 Montelukast Sodium interact with any supplements?
Yes. Montelukast Sodium has documented interactions with 81 supplements in our database — Nutmeg is not one of them. The Montelukast Sodium interaction page linked on this page lists every one, ranked by severity.
