European Mandrake and Effient

Here is the interaction we found between these two, with the evidence behind it.

Moderate

ORAL DRUGS

Why this applies to Effient

Effient falls under ORAL DRUGS — the group European Mandrake interacts with.

Theoretically, concurrent use might increase absorption of some drugs because of inhibited gastrointestinal (GI) motility caused by European mandrake.
Severity Moderate Likelihood Probable Evidence D

Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

First things first: European mandrake is genuinely toxic, and I'd urge you not to take it in any form. Setting that aside, here's the theoretical concern with your Effient (prasugrel). Mandrake's tropane alkaloids slow down how fast your gut moves things along. When the gut empties more slowly, a medication can sit there longer and potentially get absorbed a bit more fully.

For Effient, which thins your blood by stopping platelets from clumping, more absorption could mean a slightly stronger blood-thinning effect. In real life that might show up as easier bruising, nosebleeds, or bleeding that's slow to stop. I want to be honest though: this is based on theory and pharmacology, not solid studies. The bigger issue is mandrake's poisoning risk. Please talk with your pharmacist or doctor before mixing anything new with Effient.

From our pharmacist’s overview on the Effient page

“Effient (prasugrel) keeps platelets from forming clots, usually after a stent or a heart attack, and I would not pair supplements with it casually. Roughly 200 ingredients on this list can thin the blood further and raise bleeding risk, including two of the five rated major.”

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.
