Cycloxan 1gm Injection is a chemotherapy drug containing the active constituent cyclophosphamide. It is used to treat various malignancies (abnormal production of cells is called cancer, and if they spread to other organs then they are called malignancies). Cycloxan 1gm Injection can be used to treat malignant lymphomas (cancers that start from the lymphatic system of the body- vessels, fluid, and lymphoid tissue) such as Hodgkin’s disease, lymphocytic lymphoma, and mixed-cell type lymphoma. It is used to treat leukemias, neuroblastoma, ovarian cancer, retinoblastoma, and breast carcinoma. It can also treat Minimal Change Nephrotic syndrome in pediatric patients (kidney disease in which large quantities of protein are lost in urine). Cycloxan 1gm Injection is contraindicated in pregnancy, patients with acute infections, urinary tract infections, urinary outflow obstruction, and bone marrow disorders. Treatment with this medicine may lead to immune suppression, bone marrow failure, cardiotoxicity, renal toxicity, pulmonary toxicity, and secondary malignancies.
