Dong Quai and Selexipag

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

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Selexipag

Selexipag falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Dong Quai interacts with.

Theoretically, dong quai may increase the risk of bleeding when used with anticoagulant or antiplatelet drugs; however, research is conflicting.
Animal studies suggest that dong quai has antithrombin activity and inhibits platelet aggregation due to its coumarin components. Additionally, some case reports in humans suggest that dong quai can increase the anticoagulant effects of warfarin. However, clinical research in healthy adults shows that taking 1 gram of dong quai root daily for 3 weeks does not significantly inhibit platelet aggregation or cause bleeding. Until more is known, use dong quai with caution in patients taking antiplatelet/anticoagulant drugs.
Severity Moderate 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

Here's the honest picture: this caution is really about bleeding, not about how Selexipag works in your lungs. Selexipag doesn't thin your blood the way warfarin or aspirin do. It's grouped here because it can have mild effects on platelets, the cells that help blood clot. Dong Quai contains natural coumarin compounds that, at least in lab and animal studies, may also nudge blood toward thinning.

So the theory is that combining the two could slightly raise your chance of bruising or bleeding more easily. I'll be straight with you though: the human evidence is weak and mixed, and one study of 1 gram daily didn't show real bleeding problems. It's mostly a caution flag, not an alarm. Still, since you're managing PAH, please run Dong Quai by your pharmacist or doctor first.

From our pharmacist’s overview on the Selexipag page

“People take selexipag (Uptravi) for pulmonary arterial hypertension, dangerously high pressure in the arteries of the lungs, and that diagnosis raises the stakes on this list of 291 interacting supplements. I would treat it with real vigilance.”
