Ganciclovir can lower the number of white blood cells in your blood, increasing the chance of getting an infection. It can also lower the number of platelets, which are necessary for proper blood clotting. If this occurs, there are certain precautions you can take to reduce the risk of infection or bleeding:
Check with your doctor immediately if you think you are getting an infection or if you get a fever or chills.
Check with your doctor immediately if you notice any unusual bleeding or bruising; black, tarry stools; blood in urine or stools; or pinpoint red spots on your skin.
Be careful when using a regular toothbrush, dental floss, or toothpick. Your medical doctor, dentist, or nurse may recommend other ways to clean your teeth and gums. Check with your medical doctor before having any dental work done.
Be careful not to cut yourself when you are using sharp objects such as a safety razor or fingernail or toenail cutters.
The use of birth control is recommended for both men and women. Women should use effective birth control methods while receiving this medicine. Men should use a condom during treatment with this medicine and for at least 90 days after treatment has been completed.
It is very important that your doctor check you at regular visits for any blood problems that may be caused by this medicine.
If you have CMV retinitis: It is also very important that your ophthalmologist (eye doctor) check your eyes at regular visits since it is still possible that you may have some loss of eyesight during ganciclovir treatment.
