Interactions
7. DRUG INTERACTIONS 7.1 Effect of Other Drugs on Cyclophosphamide Exposure Protease Inhibitors Concomitant use of protease inhibitors may increase the concentration of cytotoxic metabolites and may enhance the toxicities of cyclophosphamide, including higher incidence of infections, neutropenia, and mucositis. Monitor for increased toxicities in patients receiving protease inhibitors. 7.2 Drugs That Potentiate Cyclophosphamide Toxicities Radiation therapy or drugs with similar toxicities to Cyclophosphamide for Injection can potentiate toxicities for cyclophosphamide.
Warnings
5 WARNINGS AND PRECAUTIONS • Myelosuppression, Immunosuppression, Bone Marrow Failure and Infections: Severe immunosuppression may lead to serious and sometimes fatal infections. Close hematological monitoring is required. ( 5.1 ) • Urinary Tract and Renal Toxicity: Hemorrhagic cystitis, pyelitis, ureteritis, and hematuria can occur. Urotoxicity can be fatal. Exclude or correct any urinary tract obstructions prior to treatment. ( 5.2 ) • Cardiotoxicity: Myocarditis, myopericarditis, pericardial effusion, arrythmias and congestive heart failure, which may be fatal, have been reported. Monitor patients, especially those with risk factors for cardiotoxicity or pre-existing cardiac disease. 4 CONTRAINDICATIONS •Hypersensitivity Cyclophosphamide for Injection is contraindicated in patients who have a history of severe hypersensitivity reactions to cyclophosphamide, any of its metabolites, or to other components of the product. Anaphylactic reactions including death have been reported with cyclophosphamide. Cross-sensitivity with other alkylating agents can occur.
Pregnancy
8.1 Pregnancy Risk Summary Based on its mechanism of action and published reports of effects in pregnant patients or animals, Cyclophosphamide for Injection can cause fetal harm when administered to a pregnant woman [ see Clinical Pharmacology ( 12.1 ) and Nonclinical Toxicology ( 13.1 ) ]. Exposure to cyclophosphamide during pregnancy may cause fetal malformations, miscarriage, fetal growth retardation, and toxic effects in the newborn [ see Data ]. Cyclophosphamide is teratogenic and embryo-fetal toxic in mice, rats, rabbits and monkeys [ see Data ].
