Fresenius kabi received a report that due to a citrate reaction during an apheresis procedure, calcium carbonate 500mg (tums) and saline was given to a donor halfway through the procedure.The donor reported feeling better and the donation continued.At the end of the donation, the donor presented with paresthesia, stiffness in hands and feet, numbness of the face and a tingling sensation.The donor was then given another 500mg calcium carbonate tablet.No improvement was evidenced, so the donor was sent to the emergency department.In the emergency department, serum tests were performed, and low levels of calcium were found.No additional information was able to be ascertained for this event and it is unknown what treatment was received by the donor in the emergency room.It was reported that they were hospitalized for a day and a half.Although these are known possible side effects of an apheresis procedure, fresenius kabi is reporting this event conservatively as it is not known what treatment the donor was given in the hospital.".
