What to know
If you get a fever during your chemotherapy treatment, it’s a medical emergency.
Steps to take
Fever may be the only sign that you have an infection, and an infection during chemotherapy can be life-threatening. You should take your temperature any time you feel warm, flushed, chilled, or not well. Call your doctor immediately if you have a temperature of 100.4ºF (38ºC) or higher.
You should also:
- Find out from your doctor when your white blood cell count is likely to the be the lowest, since this is when you're most at risk for infection.
- Keep a working thermometer in a convenient location and know how to use it.
- Always keep your doctor's phone number nearby. Make sure you know which number to call when their office is open and closed.
- If you go to the emergency room, tell the person checking you in that you are a cancer patient undergoing chemotherapy. If you have a fever, you might have an infection. This is a life-threatening condition, and you should be seen quickly.
