Take this medicine exactly as directed by your doctor. Do not change the dose or stop using this medicine without checking first with your doctor. When your supply of this medicine is running low, contact your doctor or pharmacist ahead of time. Do not allow yourself to run out of this medicine.

This medicine should come with a patient information insert. Read and follow these instructions carefully. Ask your doctor if you have any questions.

It is important that you take this medicine with food. This is to make sure the medicine is fully absorbed into the body and will work properly.

Swallow the tablet whole. Do not break, crush, or chew it.

Be careful not to handle crushed or broken tablets. If you have contact with broken or crushed tablets or mixed oral liquid, wash your skin with soap and clear water. If the medicine gets into your eyes, rinse them with clear water.

If you are using the oral liquid, use the oral dispenser that comes with the package to measure each dose accurately. The average household teaspoon may not hold the right amount of liquid.

If you are taking ganciclovir (Cytovene®) capsules before switching to valganciclovir (Valcyte®) tablets, the dose of your medicine may change. Although these medicines both treat the same problem, they are absorbed differently by your body. Make sure you understand the new directions for Valcyte® so you do not take too many tablets.

To get the best results, valganciclovir must be given for the full time of treatment. Also, this medicine works best when there is a constant amount in the blood. To help keep the amount constant, valganciclovir must be taken on a regular schedule.
