Drug & supplement interaction

European Mistletoe + Gabapentin

Gabapentin brand names: Neurontin, Gralise.

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 Gabapentin 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 Gabapentin

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 Gabapentin 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 Gabapentin

Interactions in our licensed database are recorded against drug classes, not just single drug names. Gabapentin is filed under 4 classifications — including anticonvulsants, cns depressants, oral drugs. European Mistletoe has documented interactions with 2 drug classes — the most serious being antihypertensive drugs (moderate) and immunosuppressants (moderate) — and none of Gabapentin’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 Gabapentin 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. 5 of them are worth acting on rather than waiting out — marked below.

    European Mistletoe

    “Orally, European mistletoe seems to be well tolerated when used in small amounts. However, a thorough evaluation of safety outcomes has not been conducted. Parenterally, European mistletoe may be safe when administered by a healthcare provider.”

    “Orally, European mistletoe may cause seizures, coma, and death (18). Subcutaneously, European mistletoe can cause headaches or fatigue or malaise. When injected into the tumor, European mistletoe can cause headaches. Intravenous infusion of aviscumine, a pure form of mistletoe lectin I produced by recombinant DNA techniques, can cause fatigue.”

Overlapping uses

What Gabapentin Is Prescribed For, and What European Mistletoe Has Been Studied For

These two come up together because they touch the same health topic — not because they do the same job. Gabapentin is a prescription medicine with approved uses on its FDA label. European Mistletoe is a supplement: what follows is what researchers have looked at it for, and how strong that evidence is.

Gabapentin is prescribed for: Gabapentin (brands include Neurontin, Relgaabi, Gabarone, Gralise, and Horizant) is primarily used to manage postherpetic neuralgia (PHN) — the nerve pain that lingers after a shingles outbreak — in adults. Neurontin, Relgaabi, Gabarone, and gabapentin capsules, tablets, and oral solution are also used as add-on therapy for partial onset seizures (a type of epilepsy) in adults and children aged 3 and older. Horizant (gabapentin enacarbil extended-release tablet) has two specific approvals: treatment of moderate-to-severe primary restless legs syndrome (RLS) in adults, and management of postherpetic neuralgia in adults. Horizant is not recommended for people who need to sleep during the day and stay awake at night.

Read the rest of what Gabapentin is prescribed for

Gralise is approved only for postherpetic neuralgia and cannot be substituted for other gabapentin products due to its different release profile.

  • Epilepsy studied, not established European Mistletoe has been studied for this. Natural Medicines rates the evidence: Insufficient Reliable Evidence To Rate Read what the research shows

    European Mistletoe for epilepsy

    Although there has been interest in using oral European mistletoe for epilepsy, there is insufficient reliable information about the clinical effects of European mistletoe for this purpose.

Effectiveness ratings and the research summaries above are the verbatim record from the Natural Medicines database, which grades evidence from “Effective” down to “Insufficient Reliable Evidence To Rate”. A rating below the top of that scale means researchers have looked at it — not that it works, and never that it can stand in for a prescribed medicine. Do not stop or replace Gabapentin on your own; if you are taking European Mistletoe for the same health topic, tell your prescriber, especially if the medicine is being adjusted to a target.

From our pharmacist’s overview on the Gabapentin page

“Gabapentin (Neurontin, Gralise) calms overactive nerves, which means it already slows your nervous system down, and that is exactly what 78 of the 106 supplements on this list also do. So the dominant risk here is sedation stacked on sedation, extra drowsiness at best and dangerously slowed breathing at worst, and with seven entries ra…”

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 Gabapentin Together: Common Questions

Is it safe to take European Mistletoe with Gabapentin?
We do not list a known interaction between European Mistletoe and Gabapentin. 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 Gabapentin 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.
Are European Mistletoe and Gabapentin used for the same thing?
They overlap in purpose, which usually means the real question is whether you need both rather than whether they are safe together. This page lists the shared uses and how strong the evidence is for European Mistletoe in each. That is a conversation for your prescriber, especially if Gabapentin is being adjusted to a target.
How was the European Mistletoe and Gabapentin combination checked?
Interactions in our licensed database are recorded against drug classes. Gabapentin is filed under 4 classifications, and European Mistletoe has documented interactions with 2 drug classes — none of Gabapentin'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 — Gabapentin 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 Gabapentin interact with any supplements?
Yes. Gabapentin has documented interactions with 106 supplements in our database — European Mistletoe is not one of them. The Gabapentin interaction page linked on this page lists every one, ranked by severity.
