Common side effects include nausea, vomiting, diarrhea, and headache, but these are usually mild and self-resolving. However, some patients may experience severe side effects such as neutropenia, anemia, and liver damage. Therefore, it is important to inform the doctor about any allergies or other medications used before starting treatment with valganciclovir.

In addition, valganciclovir is contraindicated in pregnant and lactating women due to the potential adverse effects on the fetus or infant. For patients with impaired liver function, a lower dose should be used, and close collaboration with the doctor is necessary to monitor for adverse reactions.

In conclusion, valganciclovir is a commonly used antiviral drug, especially for the prevention and treatment of CMV infection after liver transplantation. However, it is important to follow the doctor's guidance and pay close attention to the side effects and contraindications associated with its use.
