Drug & supplement interaction

Hedge Mustard + Lansoprazole

Lansoprazole brand name: Prevacid.

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 Hedge Mustard and Lansoprazole 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.

Hedge Mustard and Lansoprazole

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 Lansoprazole and Hedge Mustard 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 Lansoprazole

Interactions in our licensed database are recorded against drug classes, not just single drug names. Lansoprazole is filed under 5 classifications — including proton pump inhibitors (ppis), cytochrome p450 1a2 (cyp1a2) inducers, cytochrome p450 2c19 (cyp2c19) substrates. Hedge Mustard has documented interactions with 6 drug classes — the most serious being digoxin (lanoxin) (moderate), diuretic drugs (moderate) and macrolide antibiotics (moderate) — and none of Lansoprazole’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 Hedge Mustard and Lansoprazole 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.

From our pharmacist’s overview on the Lansoprazole page

“Heartburn and reflux send plenty of people toward both lansoprazole (Prevacid) and the supplement aisle, and that pairing calls for genuine care, since three of the 153 ingredients on file here carry major-rated interactions. Most of the list works through the liver enzymes that clear lansoprazole, either slowing them down (grapefruit,…”

About Hedge Mustard

What is Hedge Mustard?

  • Hoarseness and voice loss
  • Sore throat
  • Cough
  • Mild laryngitis
  • Throat irritation

Hedge mustard is a traditional European herb long nicknamed the 'singer's plant' because it was used to soothe hoarseness and sore throats. Solid scientific evidence for these uses is very limited, so it is best seen as a folk remedy rather than a proven treatment. Talk to your pharmacist or doctor before using it, and avoid it during pregnancy and breastfeeding.

Sisymbrium officinale · Brassicaceae · Aerial parts (leaves, stems, flowers) and seeds · Tea, syrup, tincture, lozenges, gargle/throat preparations

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

Hedge Mustard: dosing

There is no well-established standardized dose for hedge mustard. Traditional use involves teas, syrups, and tinctures made from the aerial parts of the plant, but amounts vary widely between products and recipes.If you choose to use a commercial product, follow the directions on the label and do not exceed the recommended amount.

About Lansoprazole

What Is Lansoprazole Used For?

Brand name: Prevacid

Lansoprazole is prescribed for a range of conditions where excess stomach acid is the problem. It treats active stomach and duodenal ulcers (sores in the stomach or upper small intestine), helps heal ulcers caused by NSAID pain relievers, and can reduce the risk of those ulcers coming back.

It's also used for gastroesophageal reflux disease (GERD), erosive esophagitis (acid damage to the esophagus), and rare conditions where the stomach makes far too much acid — like Zollinger-Ellison syndrome. When combined with antibiotics, it helps wipe out H. pylori bacteria that cause recurring ulcers.

Most-Reported Side Effects for Lansoprazole

From FAERS, the FDA’s public side-effect reporting system (177,063 reports, all brands). Reports are voluntary and are not proof the drug caused the effect.

Chronic kidney disease 32,791 reports
Acute kidney injury 18,792 reports
Renal failure 13,844 reports
End stage renal disease 9,798 reports
Renal injury 9,520 reports

Taking Hedge Mustard and Lansoprazole Together: Common Questions

Is it safe to take Hedge Mustard with Lansoprazole?
We do not list a known interaction between Hedge Mustard and Lansoprazole. 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 Hedge Mustard and Lansoprazole have any of the same side effects?
Yes — our sources link each of them separately to 3 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 Hedge Mustard and Lansoprazole combination checked?
Interactions in our licensed database are recorded against drug classes. Lansoprazole is filed under 5 classifications, and Hedge Mustard has documented interactions with 6 drug classes — none of Lansoprazole'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 Hedge Mustard interact with any other medications?
Yes. Hedge Mustard has 133 documented drug interactions in our database — Lansoprazole 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 Lansoprazole interact with any supplements?
Yes. Lansoprazole has documented interactions with 153 supplements in our database — Hedge Mustard is not one of them. The Lansoprazole interaction page linked on this page lists every one, ranked by severity.
