One of the major and reversible cause of thrombocytopenia is drug-induced thrombocytopenia. We herein report a Guillain-Barre case developed thrombocytopenia after intravenous immunoglobulin (IVIG) administration. A 36-year-old female patient, who diagnosed as Guillain Barre and had an idiopathic thrombocytopenic purpura attack 18 month ago, treated 5 day course of 30 g/day dose of IVIG. Initial thrombocyte level of the patient was 193×103/?L, but its level was observed on further days after IVIG administration as 62.8×103/?L and 5.74×103/?L, respectively. Platelet counts did not respond to the pulse methylprednisolone so cyclosporine therapy was applied. Patient's platelet counts became to normal ranges after cyclosporine treatment.
