Drug Interactions between Cytoxan and Valcyte

Using valGANciclovir together with cycloPHOSphamide may increase the risk of kidney damage and/or side effects that affect your bone marrow function, resulting in low numbers of different types of blood cells. You may be more likely to develop anemia, bleeding problems, or infections due to low blood cell counts. Symptoms of kidney damage include swelling, weight gain, shortness of breath, drowsiness, confusion, mood changes, increased thirst, loss of appetite, nausea, vomiting, pain in your lower back, and urinating more or less than usual or not at all. Let your doctor know if you develop some or all of these symptoms during treatment with these medications. You should also seek medical attention if you develop paleness, fatigue, dizziness, fainting, unusual bruising or bleeding, fever, chills, diarrhea, sore throat, muscle aches, shortness of breath, blood in phlegm, weight loss, red or inflamed skin, body sores, and pain or burning during urination. Talk to your doctor if you have any questions or concerns. Your doctor may already be aware of the risks, but has determined that this is the best course of treatment for you and has taken appropriate precautions and is monitoring you closely for any potential complications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
