Overview

Systematic review finds reduced-dose DOACs lower major bleeding risk in patients with venous thromboembolism, suggesting a safer alternative.

Key Points

  • Reduced-dose DOACs significantly lower major bleeding risk while maintaining efficacy for venous thromboembolism prevention.
  • In a meta-analysis of five RCTs with 8,781 patients, odds ratios indicated similar rates of recurrent VTE between doses.
  • Randomized controlled trials compared reduced-dose apixaban and rivaroxaban to standard doses over at least 12 months.
  • Findings highlight the need for further research to identify the optimal populations for reduced-dose anticoagulation.
