Neurotoxicity Caused by Valacyclovir in a Patient on Hemodialysis

Abstract

The authors report toxicity caused by valacyclovir in a patient on hemodialysis. After initial recuperation resulting from treatment with hemodialysis, the patient experienced a relapse of neurologic symptoms, again necessitating hemodialysis. Although acyclovir and its analogues are generally safe drugs, they should be used with caution in patients with end-stage renal disease. Therapeutic drug monitoring may be indicated.
