Which of the following is a potential side effect of Multiple Myeloma treatments?

• A. Myelosuppression
• B. Increased hair growth
• C. Hearing loss
• D. Skin tanning

Answer: (A)

Myelosuppression is a common side effect because many multiple myeloma therapies are cytotoxic and affect rapidly dividing cells, including the bone marrow. When the bone marrow is suppressed, production of red cells, white cells, and platelets falls, leading to fatigue from anemia, higher infection risk from neutropenia, and increased bleeding risk from thrombocytopenia. Regular blood counts guide monitoring and management, which may include dose adjustments, growth factors, or transfusions as needed. Increased hair growth and skin tanning aren’t typical adverse effects of standard myeloma regimens, and hearing loss is more associated with certain platinum-based drugs, not the usual myeloma therapies.
