Yohimbe and Nadroparin

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

Minor

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Nadroparin

Nadroparin falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Yohimbe interacts with.

Theoretically, combining yohimbe bark with antiplatelet or anticoagulant drugs might have additive effects; however, this has not been reported in clinical research.
Research in healthy adults shows that taking yohimbine, a constituent of yohimbe bark, in doses of 8 mg or more, seems to inhibit platelet aggregation in vitro by binding to the alpha-2 adrenoceptor. The effects of yohimbe bark itself are unclear; yohimbe bark contains 0.6% to 1.38% yohimbine, but it is unclear how much is absorbed.
Severity Minor Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

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

Nadroparin (Fraxiparine) is a low molecular weight heparin, an injectable blood thinner often used to prevent or treat clots. Yohimbe's main compound, yohimbine, may slightly reduce how well platelets clump together. Stack that on top of an already powerful anticoagulant, and in theory you could see a little more bruising, slower-to-stop bleeding from cuts, or other minor bleeding.

Here's the honest part: this concern comes only from lab and animal research, and it has not shown up in real-world studies. We also don't know how much yohimbine actually gets absorbed from yohimbe bark supplements. So I'd file this as a low-level, theoretical caution rather than a red alert. Still, since you're on an injectable blood thinner, please run any yohimbe product past your pharmacist or doctor first.

This page covers Yohimbe only. If you take other supplements — a multivitamin, a sleep aid, something for joints — the Nadroparin page lists 218 supplements it has a documented interaction with, worst first, each one explained.

The most serious there right now: Activated Charcoal (major), Danshen (major), Piracetam (major), Aconite (moderate) and Allspice (moderate).

By severity: 3 major · 190 moderate · 25 minor.

From our pharmacist’s overview on the Nadroparin page

“Danshen heads my worry list for anyone on nadroparin (Fraxiparine), an injectable blood thinner used to prevent and treat clots. The herb has clot-blocking activity of its own, and since bleeding is already nadroparin's chief hazard, stacking the two invites trouble.”

About Yohimbe

What is Yohimbe?

Yohimbe
  • Erectile dysfunction
  • Low sex drive
  • Sexual performance
  • Weight loss
  • Athletic performance

Yohimbe is a West African tree bark that contains yohimbine, a compound mainly promoted for erectile dysfunction and as an aphrodisiac. A prescription form of yohimbine has some evidence for erectile dysfunction, but over-the-counter yohimbe supplements vary widely in content and can cause serious side effects like high blood pressure and fast heart rate. Because of these safety concerns, talk to your pharmacist or doctor before using it.
