Valganciclovir - Side Effects, Precautions, and Contraindications

What side effects can Valganciclovir cause?

Possible side effects from valganciclovir and their management are listed below. Please speak to your doctor if you experience any other unusual side effects.​​​

​Nausea and vomiting may occur. Your child may also experience loss of appetite but this usually resolves within a few days.
  • ​Your child may be given anti-vomiting medication to take at home—please take as prescribed, as it is easier to prevent nausea than treating.
  • Eat small but frequent meals.
  • Avoid drinking too much during meals.
  • Refrain from lying down for at least two hours after each meal.
  • Seek medical help immediately if your child experiences persistent vomiting.
Low white blood cell count. White blood cells protect the body by fighting bacteria (germs) that cause infection. When the number of white blood cells is low, your child will be more susceptible to infections.

​To help prevent infection:

  • Wash hands regularly, especially before eating and after using the bathroom.
  • Avoid crowded places and avoid contact with people who are sick.
  • Do not eat raw or undercooked food.

  • Fever (temperature of 38˚C twice or ≥38.5˚C once)
  • Bleeding in stools or urine
  • Any uncontrollable or persistent bleeding or bruising. ​
Low platelet counts.

Platelets are important for blood clotting. With low platelets, your child may bruise or bleed (e.g. gums or nose) more easily than usual.

​Be safety conscious.

Brush teeth gently with a soft-bristled toothbrush.
