Bleeding Risks and Interactions with Apixaban

Patient Factors and Bleeding Risks

• The American College of Cardiology notes that gastrointestinal bleeding is a potential side effect of apixaban 1
• Patients with renal impairment may experience higher blood levels and longer half-lives of apixaban, potentially increasing side effect risk, according to Praxis Medical Insights 2
• Elderly patients (>75 years) may be more susceptible to adverse effects of apixaban, as reported by Praxis Medical Insights 2
• The American College of Cardiology states that apixaban has a more favorable bleeding profile compared to warfarin, particularly regarding intracranial hemorrhage, and was associated with fewer overall strokes and major bleeding events compared to warfarin in the ARISTOTLE trial 1

Drug Interactions and Monitoring

• Medications that affect CYP3A4 or P-glycoprotein pathways can alter apixaban levels and increase bleeding risk, as noted by the American College of Cardiology 1
• Patients with hepatic impairment should use apixaban with caution, as it is partially metabolized by the liver, according to Praxis Medical Insights 3
