What is the highest risk period for agranulocytosis after starting therapy?

• A. First 2 weeks
• B. First year
• C. After 1 year
• D. First 26 weeks

Answer: (D)

Agranulocytosis from drugs that suppress bone marrow tends to appear earliest after therapy begins. The body’s neutrophil production is most vulnerable during the initial exposure, so the highest risk window is the first few months of treatment. Data show the peak risk occurs within about six months (roughly 26 weeks), which is when you must monitor most closely. After this early period, the risk does not remain as high, though rare cases can still occur later, so ongoing monitoring is still important but the peak danger is front-loaded in the first half-year.
