In the body, the active ingredient of the tablets, valganciclovir, is metabolized to ganciclovir. Ganciclovir prevents the virus called cytomegalovirus (CMV) from multiplying and invading healthy cells. In patients with a weakened immune system, CMV can cause an infection in the body's organs. This can pose a life-threatening threat.
