Glyburide brand names: Diabeta, Micronase, Glynase, Glycron, Micronized, and others.

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 Manna and Glyburide 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

Manna and Glyburide

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 Glyburide and Manna 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.

Manna safety at a glance

Manna overall Use caution Generally mild but can cause loose stools, gas, and cramping, especially at higher amounts.
Pregnancy Use caution Not well studied in pregnancy; use only under medical supervision.
Breastfeeding Use caution Little safety information exists, so caution is advised while breastfeeding.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Glyburide

Interactions in our licensed database are recorded against drug classes, not just single drug names. Glyburide is filed under 8 classifications — including sulfonylureas, organic anion-transporting polypeptide substrates (oatp), antidiabetes drugs. Manna has documented interactions with 4 drug classes — the most serious being digoxin (lanoxin) (moderate), diuretic drugs (moderate) and stimulant laxatives (moderate) — and none of Glyburide’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 Manna and Glyburide May Share a Side Effect

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.

  • Nausea reported in 8.4% of FDA reports for Glyburide Additional detail

    Glyburide

    Listed in the ADVERSE REACTIONS section of the FDA label for Glyburide, and in voluntary FDA adverse-event reports. Read the label on DailyMed ›

Reported for Manna but not commonly for Glyburide: bloating or gas.

Effects for Glyburide come from the ADVERSE REACTIONS section of its FDA label; effects for Manna come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 24,289 voluntary FDA FAERS reports for Glyburide 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.

About Manna

What is Manna?

Manna
  • Gentle constipation relief
  • Mild laxative for children and elderly
  • Natural sweetener
  • Occasional bowel softening

Manna is the dried, sweet sap of the flowering ash tree (Fraxinus ornus) and is best known as a gentle, mild laxative because it contains a sugar alcohol called mannitol. It is generally considered mild and is sometimes used for occasional constipation, but high-quality modern studies are limited, so talk with your pharmacist or doctor before using it.

Fraxinus ornus · Oleaceae · Dried sap (exudate) from the bark and stems · Dried flakes or pieces, syrup, powder, and as an ingredient in laxative products

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

Manna: dosing

There is no official standardized dose of manna for supplement use. Amounts have traditionally varied based on the person's age and how strong a laxative effect is needed, with smaller amounts used for children.If you choose to use a manna product, follow the directions on the label and start with the lowest amount.

Taking Manna and Glyburide Together: Common Questions

Is it safe to take Manna with Glyburide?
We do not list a known interaction between Manna and Glyburide. 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 Manna and Glyburide have any of the same side effects?
Yes — our sources link each of them separately to one 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 Manna and Glyburide combination checked?
Interactions in our licensed database are recorded against drug classes. Glyburide is filed under 8 classifications, and Manna has documented interactions with 4 drug classes — none of Glyburide'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 Manna interact with any other medications?
Yes. Manna has 99 documented drug interactions in our database — Glyburide 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 Glyburide interact with any supplements?
Yes. Glyburide has documented interactions with 331 supplements in our database — Manna is not one of them. The Glyburide interaction page linked on this page lists every one, ranked by severity.
