*Apixaban: use the SCr-based dose-reduction criteria. Edoxaban is contraindicated for AF when CrCl >95 (reduced efficacy, ENGAGE AF-TIMI 48; FDA boxed warning).

Reversal of Major Bleeding
DOACAgentDose
Apixaban / Rivaroxaban4-factor PCC (Kcentra)~50 units/kg IV for life-threatening bleeding (protocols vary)
DabigatranIdarucizumab (Praxbind)5 g IV (two 2.5 g vials)

⚠ Andexanet alfa (Andexxa) was withdrawn from the US market (Dec 2025) after ANNEXA-I showed net thrombotic harm. 4-factor PCC is now the practical Xa-inhibitor reversal option. Add tranexamic acid + supportive care; hold the DOAC; consider activated charcoal if last dose <2–4 h.

Red Flags & Pearls
🛑
Mechanical heart valve or moderate–severe mitral stenosis: DOACs are contraindicated. Warfarin only.
🍞
Take with food: rivaroxaban 15/20 mg and edoxaban require food for absorption, a common adherence failure point.
🫍
CKD/HD: apixaban has the least renal elimination and is the preferred DOAC across CrCl 15–30 and the only one FDA-labeled for HD.
Interactions: avoid with strong dual P-gp + CYP3A4 inducers (rifampin, carbamazepine) or inhibitors (azoles, ritonavir). No routine PT/INR monitoring. Dabigatran alone tracks with dTT/ECT.
