Ganciclovir is an antiviral medication used in the treatment of certain viral infections, particularly those caused by the cytomegalovirus (CMV). It belongs to a class of drugs known as nucleoside analogues.

Ganciclovir works by inhibiting the replication of the CMV virus. It is converted into its active form inside the infected cells and disrupts the viral DNA synthesis, preventing the virus from multiplying and spreading further.


The medication is available in various formulations, including oral capsules, intravenous infusion, and an ophthalmic gel for the treatment of CMV retinitis.

Common side effects of ganciclovir may include nausea, vomiting, diarrhea, and decreased blood cell counts. More serious side effects, such as kidney problems or bone marrow suppression, can occur but are less common. Regular monitoring of blood cell counts and kidney function may be recommended during treatment.


Ganciclovir should only be used under the guidance and prescription of a qualified healthcare professional experienced in the treatment of viral infections. It may interact with other medications, so it is important to inform the healthcare provider about all medications being taken, including over-the-counter drugs and supplements.

In summary, ganciclovir is an antiviral medication used in the treatment of CMV infections. It inhibits the replication of the virus to control the infection. Regular monitoring and adherence to healthcare provider instructions are important during ganciclovir treatment.
