Is acyclovir hard on the kidneys?
Acute kidney injury is an unfortunate complication of acyclovir therapy secondary to crystal-induced nephropathy. It is characterized by a decrease in renal function that develops within 24–48 hours of acyclovir administration indicated by a rapid rise in the serum creatinine.

How long does an antiviral stay in your system?
Because valacyclovir is a prodrug, it’s only active in your body for a short period of time after it’s taken. On its own, its half-life is approximately 30 minutes. However, once valacyclovir has converted into acyclovir, it has a half-life of 2.5 to 3.3 hours in people with normal renal function.

Antiviral drugs work by stopping the infection process. Depending on the virus and medicine, the blocking of the process can occur at many different locations. One drug prevents the virus from fusing to the healthy cell by blocking a receptor that helps bind the virus to the cell.
What viruses does Valtrex kill?
