Drug & supplement interaction

Marjoram + Exenatide

Exenatide brand names: Byetta, Bydureon.

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 Marjoram and Exenatide 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

Marjoram and Exenatide

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 Exenatide and Marjoram 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.

Marjoram safety at a glance

Marjoram overall Use caution Generally safe as a food, but concentrated extracts and essential oils have limited human safety data.
Pregnancy Possibly Unsafe When used in medicinal amounts; marjoram has the potential for stimulating menstruation. Avoid amounts greater than those found in foods. Read the full pregnancy detail
Breastfeeding Use caution Food amounts are likely fine, but avoid medicinal doses since safety is not established.

Pregnancy & breastfeeding ratings are from Natural Medicines (Therapeutic Research Center) — the full detail is in the Special populations card below. Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

How we checked

Why No Interaction Is Listed for Exenatide

Interactions in our licensed database are recorded against drug classes, not just single drug names. Exenatide is filed under a single classification — antidiabetes drugs. Marjoram has documented interactions with 3 drug classes — the most serious being anticholinergic drugs (moderate), anticoagulant/antiplatelet drugs (moderate) and cholinergic drugs (moderate) — and none of Exenatide’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 Marjoram and Exenatide 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.

    Marjoram

    “Possible allergic contact dermatitis in children with pre-existing childhood atopic eczema was observed in a randomized clinical trial employing extended use of essential oils, including sweet marjoram essential oil. A case report describes a 38-year old woman who had an exacerbation of perioral dermatitis after eating food seasoned with marjoram.”

Where a percentage is shown, it is the share of 52,314 voluntary FDA FAERS reports for Exenatide that mention that effect — a reporting proportion, not an incidence rate and not evidence the drug caused it.

From our pharmacist’s overview on the Exenatide page

“Because exenatide (Byetta, Bydureon) exists to lower blood sugar, nearly every supplement on this list pulls at that same lever, and I treat that as a genuine warning rather than a footnote. Most entries, including everyday items like fenugreek, bitter melon, flaxseed, and ginseng, can drop glucose further and raise the odds of hypogly…”

About Marjoram

What is Marjoram?

Marjoram
  • Digestive upset
  • Sleep and relaxation
  • Respiratory complaints (cough, congestion)
  • Menstrual discomfort
  • Aromatherapy for stress

Marjoram is a Mediterranean kitchen herb related to oregano that is widely used in food and traditional medicine for digestive, sleep, and respiratory complaints. Most of its health claims rest on traditional use and small lab or animal studies rather than strong human trials. It is generally considered safe as a food, but concentrated supplements and essential oils should be used with caution and avoided in pregnancy.

Origanum majorana · Lamiaceae · Leaves, flowering tops, and essential oil · Culinary herb, tea, capsules, tincture, essential oil (for aromatherapy)

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

Marjoram: dosing

There is no official, well-established medicinal dose for marjoram. The amounts used in research and traditional practice vary widely depending on the form.If you use a marjoram product, follow the directions on the label and do not exceed the recommended amount.

Taking Marjoram and Exenatide Together: Common Questions

Is it safe to take Marjoram with Exenatide?
We do not list a known interaction between Marjoram and Exenatide. 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 Marjoram and Exenatide 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 Marjoram and Exenatide combination checked?
Interactions in our licensed database are recorded against drug classes. Exenatide is filed under 1 classification, and Marjoram has documented interactions with 3 drug classes — none of Exenatide'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 Marjoram interact with any other medications?
Yes. Marjoram has 338 documented drug interactions in our database — Exenatide 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 Exenatide interact with any supplements?
Yes. Exenatide has documented interactions with 239 supplements in our database — Marjoram is not one of them. The Exenatide interaction page linked on this page lists every one, ranked by severity.
