[Increased perioperative blood loss during treatment with paroxetine].
A 63-year-old man who took paroxetine for depression developed massive peroperative haemorrhage during a pancreaticoduodenectomy as a result of paroxetine-induced thrombocytopathy. He lost 4 litres of blood. After administration of 8 units of fresh frozen plasma and 2 times 5 units of thrombocyte concentrate, hemostatic control was obtained and the operation could be continued. Paroxetine is a non-tricyclic serotonin reuptake inhibitor prescribed for the treatment of depression. Since this drug also blocks serotonin reuptake in platelets, a clinically significant platelet dysfunction can occur under certain conditions. Because serotonin promotes platelet aggregation, too low an amount of serotonin in the platelets can result in thrombocytopathy. Before major surgery, it is advised to perform extensive clotting tests if there is any hint of haemorrhagic diathesis in the anamnesis. In case of a prolonged bleeding time, paroxetine treatment should be stopped perioperatively.
