Tacrolimus-associated mania with psychotic symptoms in a child after renal transplant.

Tacrolimus is one of the mainstays for post-transplant immunosuppression. A variety of neuropsychiatric adverse effects have been reported above the levels of its therapeutic use. Manic symptoms associated with its use have been rarely reported. We report possibly the first such case in a child post-renal transplantation and discuss the potential neuro-immunological basis of these symptoms.
