Cyclophosphamide may damage sperm and may harm the baby if used during pregnancy. It is best to use birth control while being treated with cyclophosphamide. Tell your doctor right away if you or your partner becomes pregnant. Do not breast feed during treatment. Tell doctors or dentists that you are being treated with cyclophosphamide before you receive any treatment from them.
Some people have little or no nausea.
You may be given an antinausea drug with your treatment and a prescription to take at home. It is easier to prevent nausea than treat it once it has occurred. Follow antinausea drug directions closely. Drink plenty of liquids. Eat often in small amounts.
