		Factor Name		Myelosuppressive effects
		Factor Description		Myelosuppression, also known as bone marrow suppression, is a decrease in bone marrow activity that leads to a decrease in the production of blood cells. Some blood cell disorders include: erythrocytopenia (anemia), leukopenia (neutropenia), and thrombocytopenia (thrombocytopenia).
Mechanism Description		Additive myelosuppressive effects by the combination of Interferon gamma-1b and Clozapine

Recommended Action
Management		Caution and close monitoring are advised when clozapine is used with other agents that have a well-known potential to cause agranulocytosis or otherwise suppress bone marrow function. Agents that may be significantly myelotoxic include antineoplastic drugs, some anticonvulsant and antirheumatic medications, albendazole, chloramphenicol, colchicine, dapsone, interferons, linezolid, pentamidine, procainamide, and zidovudine.
