Drug & supplement interaction

Autumn Crocus + Omeprazole, Sodium Bicarbonate

Omeprazole, Sodium Bicarbonate brand name: Konvomep.

No Known Interaction
The bottom line No known interaction

We found no known interaction between Autumn Crocus 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.

Autumn Crocus 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 Autumn Crocus 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. Autumn Crocus has documented interactions with 1 drug class — the most serious being colchicine (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 Autumn Crocus 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. 8 of them are worth acting on rather than waiting out — marked below.

How to take them

Some Omeprazole, Sodium Bicarbonate Products Have a Food Rule — Autumn Crocus 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 — Autumn Crocus 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 Autumn Crocus 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 Autumn Crocus

What is Autumn Crocus?

Autumn Crocus
  • Gout
  • Familial Mediterranean fever
  • Joint pain and inflammation
  • Rheumatoid arthritis (traditional use)

Autumn Crocus is a highly poisonous plant that contains colchicine, a compound that has real medical value but is dangerous in its raw form. You should never eat the plant or take homemade preparations from it. If you need colchicine for gout or familial Mediterranean fever, use the standardized, FDA-approved prescription product under a doctor's supervision.

Colchicum autumnale · Colchicaceae · Corm (bulb-like underground stem), seeds, and flowers · Rarely used as a raw plant or crude extract; the purified active compound (colchicine) is available only as an FDA-approved prescription medicine

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

Autumn Crocus: dosing

There is no safe established dose of the Autumn Crocus plant as a supplement, and it should not be taken in any homemade form. The colchicine content of the plant cannot be reliably measured, so even small amounts can cause serious harm.The only appropriate way to use colchicine is through an FDA-approved prescription product, which has a precise, controlled dose set by your healthcare provider.

Taking Autumn Crocus and Omeprazole, Sodium Bicarbonate Together: Common Questions

Is it safe to take Autumn Crocus with Omeprazole, Sodium Bicarbonate?
We do not list a known interaction between Autumn Crocus 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 Autumn Crocus and Omeprazole, Sodium Bicarbonate 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.
Should I take Autumn Crocus 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 Autumn Crocus 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.
How was the Autumn Crocus and Omeprazole, Sodium Bicarbonate combination checked?
Interactions in our licensed database are recorded against drug classes. Omeprazole, Sodium Bicarbonate is filed under 10 classifications, and Autumn Crocus has documented interactions with 1 drug class — 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 Autumn Crocus interact with any other medications?
Yes. Autumn Crocus has 2 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.
Does Omeprazole, Sodium Bicarbonate interact with any supplements?
Yes. Omeprazole, Sodium Bicarbonate has documented interactions with 174 supplements in our database — Autumn Crocus is not one of them. The Omeprazole, Sodium Bicarbonate interaction page linked on this page lists every one, ranked by severity.
