Survey (n=791,California) found significant number of patients take OTC meds (particularly dietary supplements) with potentially serious interactions (SIs) with apixaban (33% took ≥1 and 6.7% multiple interacting OTC meds) and they appear to lack knowledge about potentially SIs.


Safety and efficacy outcomes of double vs. triple antithrombotic therapy in patients with atrial fibrillation following percutaneous coronary intervention

European Heart Journal

Review (4 RCTs; n= 10 234) reported lower major or clinically relevant non-major bleeding with double vs. triple antithrombotic therapy (RR 0.66, 95% CI 0.56–0.78; P < 0.0001; I2 = 69%) but at higher risk of stent thrombosis (RR 1.59, 95% CI 1.01–2.50; P = 0.04; I2 = 0%).


NIHR Signal: Significant risk of another thrombosis remains if anticoagulation is stopped

NIHR Dissemination Centre

This expert commentary of a meta-analysis (18 studies, n= 7,515) states clinical decisions to cease anticoagulation should remain tailored to each patient's circumstances and balanced against risk of bleeding.


Pharmacovigilance Risk Assessment Committee (PRAC) recommends Xeljanz (tofacitinib) be used with caution for all patients at high risk of blood clots
