Patients receiving treatment with vitamin K antagonists (VKAs) may be at increased risk of thromboembolic events (TE) due to underlying disease states. Both fatal and non-fatal arterial and venous thromboembolic complications have been reported. The potential benefits of reversing VKAs should be weighed against the potential risk of TE. Monitor patients receiving prothrombin complex concentrate (human) for signs and symptoms of TE. Resumption of anticoagulation should be carefully considered as soon as the risk of TE outweighs the risk of acute bleeding. Prothrombin complex concentrate (human) may not be suitable in patients with TE within the last 3 months prior to use .
