Valcyte (Valganciclovir)

What Valcyte is and what it is used for

Valcyte belongs to a group of medicines, which work directly to prevent the growth of viruses. In the body the active ingredient in the powder, valganciclovir, is changed into ganciclovir. Ganciclovir prevents a 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 be life threatening.

Valcyte is used:

  • for treatment of CMV-infections of the retina of the eye in patients with acquired immunodeficiency syndrome (AIDS). CMV-infection of the retina of the eye can cause vision problems and even blindness.
  • to prevent CMV-infections in patients who are not infected with CMV and who have received an organ transplant from somebody who was infected by CMV.

Before you take Valcyte

Do not take Valcyte

  • if you are allergic (hypersensitive) to valganciclovir or any of the other ingredients of Valcyte
  • if you are allergic (hypersensitive) to ganciclovir, acyclovir or valaciclovir, which are medicines used to treat other virus infections.
  • if you are breastfeeding.

Take special care with Valcyte

  • if you have low numbers of white blood cells, red blood cells or platelets (small cells involved
  • in blood clotting) in your blood. Your doctor will carry out blood tests before you start taking

Valcyte and more tests will be done while you are taking the medication.

  • if you are having radiotherapy.
  • if you have a problem with your kidneys. Your doctor may need to prescribe a reduced dose for you and may need to check your blood frequently during treatment.

Children and adolescents should not take Valcyte, as no studies have been done to see how this medicine works in children.

  • Taking other medicines

Tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.

If you take other medicines at the same time as taking Valcyte the combination could affect the amount of drug that gets into your blood stream or could cause harmful effects. Tell your doctor if you are already taking medicines that contain any of the following:

  • imipenem-cilastatin (an antibiotic). Taking this with Valcyte can cause convulsions (fits)
  • zalcitabine, zidovudine, didanosine, or similar kinds of drugs used to treat AIDS. Your doctor may reduce the dose of didanosine
  • probenecid (a medicine against gout). Taking probenecid and Valcyte at the same time could increase the amount of ganciclovir in your blood. Your doctor may prescribe a lower dose of Valcyte.
  • mycophenolate mofetil (used after transplantations) drugs used to treat cancer.
  • other drugs used against viral infections trimethoprim (an antibiotic)
