Abciximab occasionally causes severe thrombocytopenia. This is variable in severity and usually occurs within hours of administration but has been reported to present up to 8 days later. This report describes a case of life-threatening thrombocytopenia 16 days following Abciximab administration. The patient required supportive transfusions and ultimately improved following dexamethasone and intravenous immunoglobulin. The case represents the longest delay between Abciximab administration and thrombocytopenia published to date.
