Panax Ginseng and Alteplase, tPA

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

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Alteplase, tPA

Alteplase, tPA falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Panax Ginseng interacts with.

Although Panax ginseng has shown antiplatelet effects in the laboratory, it is unlikely to increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro evidence suggests that ginsenoside constituents in Panax ginseng might decrease platelet aggregation. However, research in humans suggests that ginseng does not affect platelet aggregation. Animal research indicates low oral bioavailability of Rb1 and rapid elimination of Rg1, which might explain the discrepancy between in vitro and human research. Until more is known, use with caution in patients concurrently taking anticoagulant or antiplatelet drugs.

Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans..

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the quick picture with alteplase (tPA). This is a powerful clot-busting medicine given through an IV in emergencies like strokes, heart attacks, or serious blood clots in the lungs. It already carries a real risk of bleeding on its own, which is why it's only used in a hospital under close watch.

In a lab setting, ginsenosides in Panax ginseng can make platelets a little less sticky, which in theory might add to bleeding risk. But in actual human studies, ginseng doesn't seem to meaningfully change platelet activity, so this concern stays mostly theoretical and is rated unlikely. Since tPA is only used in critical situations, just make sure the care team knows about any ginseng you take so they can keep an eye on you.

From our pharmacist’s overview on the Alteplase, tPA page

“Nobody plans to receive alteplase (Activase, tPA). It arrives by IV in an emergency to dissolve the clot behind a stroke or heart attack, so the supplements already in your system at that moment matter, and this list deserves real weight.”
