Understanding Acyclovir and Kidney Damage: Identifying Potential Side Effects
Introduction
Acyclovir is a widely used antiviral medication prescribed to treat various viral infections, including herpes simplex virus (HSV) and varicella-zoster virus (VZV). While generally considered safe, acyclovir can cause kidney damage in some individuals, particularly those with pre-existing kidney problems or those taking other medications that may interact with acyclovir. In this article, we will explore the potential side effects that may indicate kidney damage from acyclovir.
What is Acyclovir?
Acyclovir is a synthetic nucleoside analog that works by inhibiting viral DNA synthesis, thereby preventing the replication of the virus. It is available in various forms, including oral tablets, capsules, and topical creams. Acyclovir is commonly used to treat HSV-1 and HSV-2 infections, as well as VZV infections, such as shingles.
