Drug & supplement interaction

Galphimia Glauca + Zafirlukast

Zafirlukast brand name: Accolate.

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 Galphimia Glauca and Zafirlukast 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

Galphimia Glauca and Zafirlukast

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 Zafirlukast and Galphimia Glauca 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 Zafirlukast

Interactions in our licensed database are recorded against drug classes, not just single drug names. Zafirlukast is filed under 4 classifications — including cytochrome p450 2c9 (cyp2c9) inhibitors, cytochrome p450 2c9 (cyp2c9) substrates, cytochrome p450 3a4 (cyp3a4) inhibitors. Galphimia Glauca has documented interactions with 1 drug class — the most serious being cns depressants (moderate) — and none of Zafirlukast’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 Galphimia Glauca and Zafirlukast 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.

  • Headache reported in 5.2% of FDA reports for Zafirlukast Additional detail

    Galphimia Glauca

    “Orally, Galphimia glauca extract 7-14 mg daily has been associated with sedation and headache. Rarely, restlessness, nervousness, weakness, and other side effects have been reported; but it is unclear if Galphimia glauca was the causal factor.”

Reported for Galphimia Glauca but not commonly for Zafirlukast: anxiety or restlessness and drowsiness.

Effects for Zafirlukast come from the ADVERSE REACTIONS section of its FDA label; effects for Galphimia Glauca come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 864 voluntary FDA FAERS reports for Zafirlukast 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.

Overlapping uses

What Zafirlukast Is Prescribed For, and What Galphimia Glauca Has Been Studied For

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

Zafirlukast is prescribed for: Zafirlukast tablets are used for the prophylaxis (prevention) and chronic treatment of asthma in adults and children 5 years of age and older. It is taken daily to help control ongoing asthma symptoms — not to relieve a sudden asthma attack. It is available under the brand names Accolate and Zafirlukast as an oral tablet.

Galphimia Glauca has been studied for:

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

    Galphimia Glauca for asthma

    Although there has been interest in using oral Galphimia glauca for asthma, there is insufficient reliable information about the clinical effects of Galphimia glauca for this condition.

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 Zafirlukast on your own; if you are taking Galphimia Glauca for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

Taking Galphimia Glauca and Zafirlukast Together: Common Questions

Is it safe to take Galphimia Glauca with Zafirlukast?
We do not list a known interaction between Galphimia Glauca and Zafirlukast. 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 Galphimia Glauca and Zafirlukast have any of the same side effects?
Yes — our sources link each of them separately to 2 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.
Are Galphimia Glauca and Zafirlukast 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 Galphimia Glauca in each. That is a conversation for your prescriber, especially if Zafirlukast is being adjusted to a target.
How was the Galphimia Glauca and Zafirlukast combination checked?
Interactions in our licensed database are recorded against drug classes. Zafirlukast is filed under 4 classifications, and Galphimia Glauca has documented interactions with 1 drug class — none of Zafirlukast'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 Galphimia Glauca interact with any other medications?
Yes. Galphimia Glauca has 248 documented drug interactions in our database — Zafirlukast 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 Zafirlukast interact with any supplements?
Yes. Zafirlukast has documented interactions with 88 supplements in our database — Galphimia Glauca is not one of them. The Zafirlukast interaction page linked on this page lists every one, ranked by severity.
