Valacyclovir-induced neurotoxicity and nephrotoxicity in an elderly patient with a history of nephrectomy: a case report

This case report demonstrates a rare case of acute kidney injury due to an exaggerated response to valacyclovir-induced crystal nephropathy, presenting in tandem with valacyclovir-induced neurotoxicity, which has only been described in three case reports. This case highlights the importance of careful history and physical exam to facilitate a more accurate and timely diagnosis, especially in patients with a history of nephrectomy.
