What is the most severe adverse effect associated with Chloramphenicol use?

• A. Aplastic Anemia
• B. Gray baby syndrome
• C. Nephrotoxicity
• D. Hepatotoxicity

Answer: (A)

Chloramphenicol carries a risk of bone marrow suppression, and the gravest consequence of that suppression is aplastic anemia. This condition is a serious, often irreversible failure of the bone marrow to produce red cells, white cells, and platelets. It can be fatal because infections and bleeding become major threats once blood cell production collapses, and stopping the drug doesn’t reliably reverse the damage. Because it isn’t reliably dose-related and can occur with varying exposure, it’s unpredictable and potentially life-threatening, which is why it’s considered the most severe adverse effect. Neonates can develop Gray baby syndrome with chloramphenicol, due to immature liver enzymes, leading to pallor, cyanosis, hypotension, and shock. It’s very dangerous in infants, but the overall most severe risk when considering all populations is aplastic anemia. Other adverse effects like nephrotoxicity or hepatotoxicity can occur but are generally less catastrophic than the risk of irreversible bone marrow failure.
