No Known Interaction

Medically reviewed by Dr. Brian Staiger, PharmD, BCPS · Updated July 2026 · Pair last verified Sep 13, 2026

The bottom line No known interaction

We found no known interaction between Broccoli Sprout and Mepolizumab 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

Broccoli Sprout and Mepolizumab

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 Mepolizumab and Broccoli Sprout 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.

What to actually watch for

No Interaction Found — But Data Suggests Broccoli Sprout and Mepolizumab 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.

Stomach pain / Diarrhea Additional detail
Broccoli Sprout
“Orally, loose stools, diarrhea, abdominal pain, and abdominal cramping have been reported following intake of broccoli seed and broccoli sprout extracts, particularly at high doses. Consuming raw broccoli sprouts that have been improperly grown may cause food-borne illness. Improperly grown broccoli sprouts may be contaminated with bacteria, including Listeria monocytogenes, Salmonella, or Escherichia coli O157:H7.”

Special populations

Broccoli Sprout in Pregnancy & Breastfeeding

Pregnancy And Lactation Likely Safe

When COOKED broccoli sprouts are consumed in amounts commonly found in foods. Broccoli sprout is considered safe for dietary consumption provided the sprouts are grown in accordance with food safety recommendations developed by the US Food and Drug Administration (FDA) and are cooked prior to eating.

Pregnancy And Lactation Possibly Unsafe

When RAW broccoli sprouts are consumed in amounts commonly found in foods. There is evidence that uncooked broccoli sprouts may be contaminated with bacteria, including Listeria monocytogenes, Salmonella, or Escherichia coli O157:H7. Pregnant individuals are particularly susceptible to these food-borne illnesses, and becoming infected can increase the risk of miscarriage, stillbirth, premature birth, or neonatal infection. There is insufficient reliable information available about the safety of broccoli sprout extract during pregnancy or lactation; avoid using.

Overlapping uses

What Mepolizumab Is Prescribed For, and What Broccoli Sprout Has Been Studied For

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

Mepolizumab is prescribed for: Nucala is used as an add-on maintenance treatment — meaning it works alongside other medications, not instead of them. It is approved for severe asthma (in patients 6 years and older with high eosinophil levels), chronic rhinosinusitis with nasal polyps (CRSwNP) in adults 18 and older whose symptoms aren't controlled by nasal corticosteroids alone, and COPD in adults with an eosinophilic phenotype whose disease isn't adequately controlled. Nucala is also approved to treat eosinophilic granulomatosis with polyangiitis (EGPA), a rare form of blood vessel inflammation, and hypereosinophilic syndrome (HES), a condition involving dangerously elevated eosinophil counts, in adults and adolescents 12 and older. It is not meant to relieve sudden asthma attacks or acute COPD flares.

Broccoli Sprout has been studied for:

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

Broccoli Sprout for asthma

Although there has been interest in using oral broccoli sprout extract for asthma, there is insufficient reliable information about the clinical effects of broccoli sprout 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 Mepolizumab on your own; if you are taking Broccoli Sprout for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

About Broccoli Sprout

What is Broccoli Sprout?

Antioxidant support
Detoxification support
General heart health
Anti-inflammatory support
Digestive and gut health

Broccoli sprouts are young broccoli seedlings rich in a compound called sulforaphane, which is being studied for antioxidant, anti-inflammatory, and detoxification effects. Early research is promising for some uses, but high-quality human evidence is still limited, so they should be viewed as a healthy food rather than a proven treatment. As food they are generally safe, but talk to your pharmacist or doctor before using concentrated supplements, especially during pregnancy or breastfeeding.

Brassica oleracea var. italica · Brassicaceae · Young sprouts (seedlings) of the broccoli plant · Fresh sprouts, powders, capsules, tablets, and standardized extracts (often labeled as containing sulforaphane or glucoraphanin)

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

Broccoli Sprout: dosing

There is no official standardized dose for broccoli sprouts or their extracts. Studies have used different forms and amounts, often described by the amount of glucoraphanin or sulforaphane, which makes comparison difficult.If you are eating them as food, a serving as part of a balanced diet is reasonable. If you choose a supplement, follow the directions on the product label and choose a reputable brand.

Taking Broccoli Sprout and Mepolizumab Together: Common Questions

Is it safe to take Broccoli Sprout with Mepolizumab?

We do not list a known interaction between Broccoli Sprout and Mepolizumab. 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 Broccoli Sprout and Mepolizumab 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 Broccoli Sprout and Mepolizumab 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 Broccoli Sprout in each. That is a conversation for your prescriber, especially if Mepolizumab is being adjusted to a target.

Does Broccoli Sprout interact with any other medications?

Yes. Broccoli Sprout has 187 documented drug interactions in our database — Mepolizumab is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
