		Factor Description		Immunosuppression is when your immune system is not functioning as it should. The immune system is made up of cells, tissues and organs that help the body fight off infections. If the immune system is suppressed, an infection that your body was able to control may become serious or even fatal.
Mechanism Description		Additive immunosuppressive effects by the combination of Tositumomab and Alemtuzumab

Recommended Action
Management		Caution is advised if alemtuzumab must be used in patients who have recently received or are receiving treatment with other immunosuppressive or myelosuppressive drugs, and vice versa. The manufacturer recommends that single doses of alemtuzumab not exceed 30 mg and cumulative weekly doses not exceed 90 mg, since higher dosages are associated with an increased incidence of pancytopenia. Close clinical and laboratory monitoring for the development of severe hematologic adverse effects is recommended both during and after discontinuation of therapy.
