Current as of 31 July 2026 · added 31 July 2026

Answer: The most common causes of neutropenia in hospitalized patients are medication-related (antibiotics, chemotherapy, etc.) and acute illness/infection.

  • Treatment is largely expectant — address the underlying cause or provide G-CSF support.
  • See The Blood Project for a general approach to isolated neutropenia.
