Summary Patients with cirrhosis were long thought to be coagulopathic. However, this paradigm has changed in recent years and currently, cirrhosis is recognised as a prothrombotic state. Due to the increasing incidence of cirrhosis from nonalcoholic steatohepatitis which is closely associated with cardiac disease, patients with cirrhosis increasingly require therapy with anticoagulants and antiplatelet agents. However, their potential for causing catastrophic and life‐threatening bleeding in patients with cirrhosis leads to hesitancy about their use in patients with cirrhosis. Overall, traditional anticoagulation is safe for all Child‐Pugh classes while newer direct oral anticoagulants (DOACs) are mostly safe in Child‐Pugh class A/B and contraindicated in severe hepatic impairment. For different indications, published data to date suggest that anticoagulation is overall safe for patients with cirrhosis who have venous thromboembolism, atrial fibrillation and portal vein thrombosis, and does not increase the risk of variceal bleeding. Moreover, DOACs appear to have similar safety profiles as traditional anticoagulants. Finally, most studies suggest that antiplatelet agents are also safe to use in patients with cirrhosis although they are mostly contraindicated in severe hepatic impairment. For both anticoagulants and antiplatelet agents, severe thrombocytopaenia presents a relative contraindication to their use. More prospective trials and large cohort studies are needed to advance our understanding of the safety and nuances of DOACs and antiplatelet agents in patients with advanced cirrhosis.
