Transplant patients: Prevention of CMV infection: For kidney transplant patients, the recommended dose is 900 mg (two 450 mg tablets) once daily, starting within 10 days after transplantation and continuing until 200 days after transplantation. For patients who have received a solid organ transplant other than a kidney, the recommended dose is 900 mg (two 450 mg tablets) once daily, starting within 10 days after transplantation and continuing until 100 days after transplantation.

Contraindications: Valganciclovir Hydrochloride Tablets should not be used in patients with a known allergic reaction to valganciclovir, ganciclovir, or any other ingredient in the drug.
