What the medication is used for
  • AURO-VALGANCICLOVIR is a prescription medication that belongs to the family of drugs known as “antivirals”.
  • AURO-VALGANCICLOVIR is used to treat cytomegalovirus (CMV) retinitis in adults who have acquired immunodeficiency syndrome (AIDS).
  • AURO-VALGANCICLOVIR is also used to prevent cytomegalovirus (CMV) disease in adults who have received a solid organ transplant and are at risk of developing CMV disease.

What it does
  • AURO-VALGANCICLOVIR works by slowing the growth of CMV virus, the virus that causes CMV retinitis as well as CMV infection at other sites in the body. For most people with CMV retinitis, AURO-VALGANCICLOVIR prevents CMV from progressing (spreading) into healthy cells as quickly as it would without treatment, thereby protecting eyesight from damage due to CMV disease.
  • AURO-VALGANCICLOVIR does not cure CMV retinitis, and some people may experience progression of retinitis during or following treatment with AURO-VALGANCICLOVIR. Therefore, you must follow your doctor’s advice and have your eyes checked regularly.
  • For most patients who have received a solid organ transplant, AURO-VALGANCICLOVIR prevents the occurrence of CMV disease up to 6 months after the transplant.
  • Valganciclovir hydrochloride is a prodrug of ganciclovir. This means it is changed to ganciclovir once it is absorbed into the body Ganciclovir is the active part of the drug that actually slows the growth of CMV virus.
