When to worry about unexplained fever with acute myeloid leukaemia

Unexplained Fever is a very common presentation of Acute Myeloid Leukaemia. Fever may be linked to the disease, an infection, or treatment, and a clinical assessment is needed to distinguish these causes. Acute myeloid leukaemia can reduce healthy blood-cell production, making it harder to fight infection. A person may have few localising symptoms, so a new fever deserves attention even without a cough, wound, or urinary symptom.

Use the thermometer and fever instructions supplied by your team. Note the temperature, when it began, recent chemotherapy, and symptoms such as shaking, sore throat, diarrhoea, burning urine, or redness around a line. Call the designated oncology number without waiting for the next clinic visit. Do not start leftover antibiotics or use fever medicine unless your team has advised it. Sip fluids if safe and arrange help with transport if assessment is needed.

Seek emergency help for difficulty breathing, chest discomfort, confusion, collapse, severe drowsiness, uncontrolled bleeding, or inability to drink. Urgent assessment is also needed for worsening chills, severe weakness, or a painful, red, swollen area. Tell the receiving team that you have acute myeloid leukaemia and give them your oncology contact details if available.

Ask your doctor which readings require immediate contact, how to reach the team overnight, whether your central line changes the advice, and which medicines are safe before assessment.
