Drug & supplement interaction

Scotch Broom + Omeprazole, Sodium Bicarbonate

Omeprazole, Sodium Bicarbonate brand name: Konvomep.

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 Scotch Broom and Omeprazole, Sodium Bicarbonate 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 Omeprazole, Sodium Bicarbonate 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.

Scotch Broom and Omeprazole, Sodium Bicarbonate

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 Omeprazole, Sodium Bicarbonate and Scotch Broom 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 Omeprazole, Sodium Bicarbonate

Interactions in our licensed database are recorded against drug classes, not just single drug names. Omeprazole, Sodium Bicarbonate is filed under 10 classifications — including proton pump inhibitors (ppis), cytochrome p450 2c19 (cyp2c19) inhibitors, cytochrome p450 1a2 (cyp1a2) inducers. Scotch Broom has documented interactions with 4 drug classes — the most serious being haloperidol (haldol) (major), monoamine oxidase inhibitors (maois) (major) and quinidine (major) — and none of Omeprazole, Sodium Bicarbonate’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.

No Interaction Found — But Data Suggests Scotch Broom and Omeprazole, Sodium Bicarbonate 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.

    “Scotch broom is generally regarded as unsafe for use. Any benefits of therapy may not outweigh the risk of toxicity (4,12). Orally, the sparteine constituent of Scotch broom can cause toxicity at doses greater than 300 mg of sparteine, which is roughly equivalent to 30 grams of Scotch broom.”

How to take them

Some Omeprazole, Sodium Bicarbonate Products Have a Food Rule — Scotch Broom Should Not Break It

At least one FDA label for a product containing Omeprazole, Sodium Bicarbonate says to take it on an empty stomach. Most supplements — Scotch Broom included — are taken with a meal, so the easy mistake is swallowing both together at breakfast. Where that rule applies, keep Omeprazole, Sodium Bicarbonate on its own and move Scotch Broom 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 Omeprazole, Sodium Bicarbonate 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.

• Take on an empty stomach at least one hour before a meal [see Clinical Pharmacology ( 12.3 )] .

From the Dosage and Administration section of the FDA label we read for Omeprazole, Sodium Bicarbonate — 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 Scotch Broom

What is Scotch Broom?

  • Heart rhythm and circulation complaints
  • Diuretic (increasing urine)
  • Heavy menstrual bleeding
  • Mild swelling
  • Traditional folk remedy

Scotch Broom is a flowering shrub that has been used in folk medicine for heart and circulation complaints, but it contains potentially toxic alkaloids and there is no solid scientific evidence that it works for any condition. Because it can affect heart rate and blood pressure and may be dangerous in higher amounts, most people should avoid it, and it should never be used during pregnancy or breastfeeding. Always talk with a pharmacist or doctor before trying it.

Cytisus scoparius · Fabaceae · Flowering tops and aerial parts · Tea, tincture, dried herb, occasionally capsules

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

Scotch Broom: dosing

There is no established safe or standardized dose for Scotch Broom. Because the strength of the active alkaloids varies and the plant can be toxic, it is not possible to recommend a safe amount.If a product contains Scotch Broom, follow the label exactly and do not exceed the directions.

Taking Scotch Broom and Omeprazole, Sodium Bicarbonate Together: Common Questions

Is it safe to take Scotch Broom with Omeprazole, Sodium Bicarbonate?
We do not list a known interaction between Scotch Broom and Omeprazole, Sodium Bicarbonate. 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 Scotch Broom and Omeprazole, Sodium Bicarbonate have any of the same side effects?
Yes — our sources link each of them separately to 7 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 Scotch Broom and Omeprazole, Sodium Bicarbonate at the same time of day?
At least one FDA label for a product containing Omeprazole, Sodium Bicarbonate 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 Omeprazole, Sodium Bicarbonate on its own and move Scotch Broom 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.

Interactions in our licensed database are recorded against drug classes. Omeprazole, Sodium Bicarbonate is filed under 10 classifications, and Scotch Broom has documented interactions with 4 drug classes — none of Omeprazole, Sodium Bicarbonate'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 Scotch Broom interact with any other medications?
Yes. Scotch Broom has 12 documented drug interactions in our database — Omeprazole, Sodium Bicarbonate is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
