When to worry about unexplained fever with febrile neutropenia

Unexplained Fever is a very common presentation of Febrile Neutropenia. Febrile neutropenia means fever occurs when neutrophils, which help defend against infection, are low. The usual signs of infection may be muted, and a serious infection can worsen quickly. The fever may be the first clue, even when there is no obvious wound, cough, or urinary symptom.

Follow your personal fever plan and contact the oncology or emergency team immediately. Share the temperature, time of onset, recent treatment, current medicines, and any line or wound symptoms. Do not wait for a repeat reading unless your team has specifically instructed you to do so. Do not take antibiotics left from an earlier illness or fever medicine without advice. Keep your phone available and arrange safe, rapid transport if directed.

Call emergency services for trouble breathing, chest pain, confusion, collapse, severe drowsiness, or a seizure. Tell the team immediately about uncontrolled bleeding, severe shaking, new severe pain, repeated vomiting, inability to drink, or rapidly worsening weakness. Do not go to a crowded waiting area without first following the instructions from your oncology team, because they may direct you to a specific assessment route.

Ask which temperature readings activate your plan, which number answers overnight, how to handle your central line, and which medicines or drinks are appropriate before assessment.
