Drug & supplement interaction

European Mistletoe + Glucose

Glucose brand name: IV Glucose.

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 European Mistletoe and Glucose 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

European Mistletoe and Glucose

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 Glucose and European Mistletoe 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 Glucose

Interactions in our licensed database are recorded against drug classes, not just single drug names. Glucose is filed under 3 classifications — sodium-glucose co-transporter 2 (sglt2) inhibitors, antidiabetes drugs, oral drugs. European Mistletoe has documented interactions with 2 drug classes — the most serious being antihypertensive drugs (moderate) and immunosuppressants (moderate) — and none of Glucose’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 European Mistletoe and Glucose 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. 2 of them are worth acting on rather than waiting out — marked below.

  • A higher chance of infection Worth acting on reported in 4.2% of FDA reports for Glucose Additional detail

    European Mistletoe

    “Subcutaneously, European mistletoe may cause allergic reactions or flu-like symptoms or mild infections. Early research shows that European mistletoe is not associated with an increase in side effects when it is administered in conjunction with targeted cancer treatments such as monoclonal antibodies and immunotherapy regimens, including PD-1/PD-L1 or CTLA-4 inhibitors.”

    Glucose

    Listed in the ADVERSE REACTIONS section of the FDA label for Glucose. Read the label on DailyMed ›

Reported for European Mistletoe but not commonly for Glucose: liver problems, shortness of breath, stomach pain and diarrhea.

Effects for Glucose come from the ADVERSE REACTIONS section of its FDA label; effects for European Mistletoe come from the Natural Medicines adverse-effect record, quoted above. Where a percentage is shown, it is the share of 187,593 voluntary FDA FAERS reports for Glucose 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.

See Every Supplement That Interacts With Glucose

This page covers European Mistletoe only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Glucose page lists 256 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Siberian Cocklebur (major), Acai (moderate), African Wild Potato (moderate) and Agaricus Mushroom (moderate).

By severity: 2 major · 215 moderate · 39 minor.

From our pharmacist’s overview on the Glucose page

“Glucose given by IV raises a dangerously low blood sugar, and this list warrants real caution because most of its 256 ingredients pull the other way. Nearly all of them lower blood sugar on their own, working against the treatment and setting up another crash.”

About European Mistletoe

What is European Mistletoe?

European Mistletoe
  • Cancer supportive care
  • Immune support
  • High blood pressure
  • Anxiety and stress
  • Inflammation

European mistletoe is a parasitic plant most studied as an injectable extract used alongside conventional cancer care in some European countries, mainly to improve quality of life rather than to cure cancer. The plant is toxic if eaten, and oral or self-treatment can be dangerous, so it should only be used under medical supervision. Talk to your pharmacist or doctor before using any mistletoe product.

Viscum album · Santalaceae · Leaves, stems, and young twigs (whole aerial parts) · Injectable extracts (used in some countries), capsules, tinctures, teas, and standardized extracts

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

European Mistletoe: dosing

There is no single standard dose of European mistletoe for the general public. Injectable extracts used in clinical settings are dosed and adjusted by trained health professionals based on the specific product and the person's response.Because oral mistletoe products can be toxic and are not well studied, we cannot recommend a safe home dose. Never use mistletoe to self-treat a serious condition like cancer or high blood pressure.

Taking European Mistletoe and Glucose Together: Common Questions

Is it safe to take European Mistletoe with Glucose?
We do not list a known interaction between European Mistletoe and Glucose. 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 European Mistletoe and Glucose have any of the same side effects?
Yes — our sources link each of them separately to 2 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 European Mistletoe and Glucose combination checked?
Interactions in our licensed database are recorded against drug classes. Glucose is filed under 3 classifications, and European Mistletoe has documented interactions with 2 drug classes — none of Glucose'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 European Mistletoe interact with any other medications?
Yes. European Mistletoe has 293 documented drug interactions in our database — Glucose 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 Glucose interact with any supplements?
Yes. Glucose has documented interactions with 256 supplements in our database — European Mistletoe is not one of them. The Glucose interaction page linked on this page lists every one, ranked by severity.
