Abstract
Neurological complications of tacrolimus are usually mild (tremors, paresthesia, myalgia), however, serious complications that result in encephalopathy, convulsions and coma can be seen. Serious complications are more frequently reported following liver transplants and lungs transplants than renal transplants and are typically seen when tacrolimus concentrations exceed the 15 ng/L therapeutic limit. In this article we presented our case of a renal allograft receiver with nausea, dizziness and fatigue complaints.
