Docosahexaenoic Acid (dha) and anistreplase, APSAC

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

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to anistreplase, APSAC

anistreplase, APSAC falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Docosahexaenoic Acid (dha) interacts with.

Theoretically, DHA may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Although some clinical evidence suggests that DHA might reduce collagen-stimulated platelet aggregation and thromboxane release, most clinical evidence suggests that DHA alone does not affect blood clotting. However, theoretically, when given in combination with EPA as fish oil, concomitant use with anticoagulant or antiplatelet drugs (including aspirin) might increase risk of bleeding.

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

Anistreplase (Eminase) is a powerful clot-busting drug, given in the hospital during a heart attack to dissolve a blockage. Because it actively breaks down clots, it already carries a real bleeding risk on its own. The thought here is that DHA could nudge that bleeding risk a little higher, since omega-3s may make platelets slightly less sticky.

Honestly, this is mostly theoretical. Most evidence shows DHA by itself doesn't meaningfully change clotting, and this drug is only used in a closely monitored emergency setting where your medical team is already watching for bleeding (bruising, oozing, blood in urine or stool). You won't be deciding this at home, but it's still worth telling your care team about any fish oil or DHA you take.

From our pharmacist’s overview on the anistreplase, APSAC page

“Anistreplase (Eminase) is a clot-dissolving drug given during a heart attack, and because bleeding is already its biggest hazard, this list deserves real vigilance. Almost every ingredient here has some blood-thinning or antiplatelet activity, meaning it could stack with anistreplase and make bleeding more likely or harder to stop.”
