The effects and toxicities of interferon alfa are described, and the role of the pharmacist in making decisions and providing education about biologic response modifiers (BRMs) is discussed. Interferons have both direct antitumor activity and extensive effects on the immune system.

Indications in FDA-approved labeling for interferon alfa include the treatment of hairy-cell leukemia, acquired immunodeficiency syndrome-related Kaposi's sarcoma, and genital warts; however, it also is being used successfully against early chronic myelogenous leukemia, low-grade non-Hodgkin's lymphoma, cutaneous T-cell lymphoma, and previously untreated multiple myeloma. Other malignancies that respond to treatment with interferon alfa are malignant melanoma, ovarian carcinoma, and renal cell carcinoma. The toxic pattern of interferon alfa consists of flu-like symptoms, which are seen at all doses, on all schedules, and in virtually all patients. After repeated dosing, the chronic toxicities of anorexia, weight loss, and malaise and fatigue may develop. Myelosuppression, central nervous system toxicity, increased hepatic enzyme concentrati...Continue Reading
