Rabbit antithymocyte globulin (RATG) is indicated for the treatment of acute renal transplant rejection and has also been shown to be effective as an induction immunosuppressive agent after renal transplantation. We report a patient that developed a painful sensory neuropathy within an hour of receiving RATG. The neuropathic symptoms resolved within a month, and a careful review of his medications, exposures and comorbid conditions revealed no other causes of neuropathy. Since the administration of RATG and onset of symptoms were so closely related temporally and the symptoms resolved after the cessation of RATG, we believe it is likely this medication led to the development of neuropathy.
