What is VALCYTE?
VALCYTE is a prescription antiviral medicine.
In adults, VALCYTE tablets are used:
- to treat cytomegalovirus (CMV) retinitis in people who have acquired immunodeficiency syndrome (AIDS). When CMV virus infects the eyes, it is called CMV retinitis. If CMV retinitis is not treated, it can cause blindness.
- to prevent CMV disease in people who have received a kidney, heart, or kidney-pancreas transplant and who have a high risk for getting CMV disease.
VALCYTE does not cure CMV retinitis. You may still get retinitis or worsening of retinitis during or after treatment with VALCYTE. It is important to stay under a healthcare provider’s care and have your eyes checked at least every 4 to 6 weeks during treatment with VALCYTE.
In children, VALCYTE tablets or oral solution are used:
- to prevent CMV disease in children 4 months to 16 years of age who have received a kidney transplant and have a high risk for getting CMV disease.
- to prevent CMV disease in children 1 month to 16 years of age who have received a heart transplant and have a high risk for getting CMV disease.
It is not known if VALCTYE is safe and effective in children for prevention of CMV disease in liver transplant, in kidney transplant in infants less than 4 months of age, in heart transplant in infants less than 1 month of age, in children with AIDS who have CMV retinitis, and in infants with congenital CMV infection.
