Drug & supplement interaction

European Mandrake + Fosaprepitant

Fosaprepitant brand names: Emend Injection, Focinvez.

No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 27, 2026
The bottom line No known interaction

We found no known interaction between European Mandrake and Fosaprepitant 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 Mandrake and Fosaprepitant

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 Fosaprepitant and European Mandrake 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 Fosaprepitant

Interactions in our licensed database are recorded against drug classes, not just single drug names. Fosaprepitant is filed under 4 classifications — including cytochrome p450 2c9 (cyp2c9) inducers, cytochrome p450 3a4 (cyp3a4) inducers, cytochrome p450 3a4 (cyp3a4) inhibitors. European Mandrake has documented interactions with 2 drug classes — the most serious being anticholinergic drugs (moderate) and oral drugs (moderate) — and none of Fosaprepitant’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 Mandrake and Fosaprepitant 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 severe allergic reaction / An allergic reaction Worth acting on Additional detail

    European Mandrake

    “Orally, European mandrake most commonly causes anticholinergic side effects including confusion, drowsiness, dry mouth, tachycardia, mydriasis, blurred vision, photophobia, decreased urination, decreased sweating and overheating, and flushing (15,17,18). Although some adverse reactions can occur even with low doses, adverse effects are dose related.”

From our pharmacist’s overview on the Fosaprepitant page

“Fosaprepitant (Emend Injection, Focinvez) is the IV drug that keeps chemotherapy from making you sick, so anything that undercuts it costs you real comfort, and I would treat this list with genuine care before adding a supplement to it. Nearly all 141 entries hinge on one liver enzyme, CYP3A4, and the traffic runs both ways, since some…”

About European Mandrake

What is European Mandrake?

European Mandrake
  • Insomnia (traditional)
  • Pain relief (historical)
  • Anxiety or depression (folk use)
  • Gout and aches (traditional)
  • Sedation or anesthesia (historical)

European mandrake is a highly toxic plant from the nightshade family that was used in ancient and medieval times as a sedative and pain reliever. It contains powerful poisons that can cause serious harm or death, and there is no proof it safely treats any condition. We strongly recommend you do not consume mandrake in any form.

Mandragora officinarum · Solanaceae · Root (and sometimes leaves and fruit) · Historically used as root preparations, extracts, and tinctures; not sold as a safe modern supplement

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

European Mandrake: dosing

There is no safe or established dose of European mandrake. It is not approved or recommended as a dietary supplement, and reputable products are not sold for internal use.Because the plant is highly toxic, we strongly advise against taking it in any amount or form.

Taking European Mandrake and Fosaprepitant Together: Common Questions

Is it safe to take European Mandrake with Fosaprepitant?

Do European Mandrake and Fosaprepitant have any of the same side effects?
Yes — our sources link each of them separately to 5 of the same effects. That is not an interaction: neither changes how your body handles the other.

How was the European Mandrake and Fosaprepitant combination checked?
Interactions in our licensed database are recorded against drug classes. Fosaprepitant is filed under 4 classifications, and European Mandrake has documented interactions with 2 drug classes — none of Fosaprepitant'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 Mandrake interact with any other medications?
Yes. European Mandrake has 2,042 documented drug interactions in our database — Fosaprepitant is simply not one of them. If you take anything else, it is worth checking each one; they are all listed on this page.
