This medicine helps stop viruses from growing, specifically the cytomegalovirus (CMV), which can cause serious infections in people with weakened immune systems.
For preventing CMV after organ transplant: two tablets once daily for up to 100 days (up to 200 days for kidney transplant patients). For initial treatment of CMV retinitis in AIDS patients: two tablets twice daily for 21 days. For long-term prevention of CMV retinitis recurrence in AIDS patients: two tablets once daily.
Handle tablets carefully. Do not split or crush them. Swallow tablets whole, preferably with food.
Do not take more tablets than your doctor has prescribed to avoid overdose. For initial CMV retinitis treatment, do not exceed 21 days unless instructed by your doctor, as this may increase side effects.
