  Cyclosporine has some very serious long-term toxicity (especially renal dysfunction and hypertension) and the availability of newer biologic agents has restricted the use of cyclosporine to patients who have not responded to conventional treatment. *Mild tremor is common with both cyclosporine and tacrolimus use, occurring in 35 to 55 percent of patients [ 79,80 ]. *Rarely, patients develop severe headache, visual abnormalities, and seizures. This syndrome is associated with acute hypertension and resembles hypertensive encephalopathy [ 77 ]. *Posterior leukoencephalopathy is usually seen on brain imaging [ 82 ]. *Cyclosporine may contribute to bone loss after organ transplantation [ 88 ]; this effect may be due to the induction of high bone turnover. *Cyclosporine can cause hyperkalemia and hypomagnesemia, via effects on renal tubular function. Hyperuricemia and exacerbation of gout are well-described with cyclosporine. [77]. Schwartz RB, Bravo SM, Klufas RA, et al.
