How quickly does idarucizumab reverse dabigatran?

Idarucizumab achieves complete reversal of dabigatran anticoagulation within minutes of administration in >98% of patients. The RE-VERSE AD trial showed median time to reversal was immediate; effect was maintained for 24 hours in most patients.

Is a second dose ever needed?

A second dose of 5 g may be considered in rare cases: rebound dabigatran effect due to redistribution from tissue compartments, or if further surgical intervention is required after initial reversal. Rebound occurs in ~1–2% of patients.

Can dialysis remove dabigatran if idarucizumab is unavailable?

Yes — dabigatran is ~35% protein-bound and can be removed by hemodialysis (~50–60% removed in 4 hours). This is an alternative when idarucizumab is unavailable, though it requires IV access and may be impractical in emergency bleeding.
