		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 Zidovudine

Recommended Action
Management		Caution is advised if concomitant therapy is necessary, particularly with the alfa interferons. Complete blood counts, differential and platelet counts should be performed regularly and drug dosages adjusted accordingly. Patients should be advised to promptly report symptoms such as chills, fever, sore throat, pale skin, or unusual fatigue to their physician. Cessation of one or all drugs may be necessary if toxicity develops.
