5 WARNING AND PRECAUTIONS
5.1 Risk of Bleeding
- Pradaxa’s anticoagulant activity and half-life are increased in patients with renal impairment.
- Lack of a specific reversal agent; futility of using vitamin K to affect anticoagulant effect
5.2 Temporary Discontinuation of PRADAXA
- Discontinuing anticoagulants, including PRADAXA, for active bleeding, elective surgery, or invasive procedures, places patients at an increased risk of stroke. Minimize lapses in therapy.
5.3 Effect of P-gp Inducers and Inhibitors on Dabigatran Exposure

Avoid use of PRADAXA and P-gp inhibitors in patients with severe renal impairment (CrCl 15-30 mL/min) [see Drug Interactions (7) and Use in Specific Populations (8.6)].”
