Should I take medicine for a fever during chemotherapy?

Talk with your doctor or nurse before taking any medicine—even aspirin, acetaminophen (such as Tylenol), or ibuprofen (such as Advil)—for a fever during cancer treatment.

These medicines can lower a fever, but they may also mask or hide the signs of a more serious problem. Because infections during treatment can be life threatening, your team needs to know about a fever before it is treated.

Call your health care team if you have a fever of 100.5°F (38°C) or higher, and follow their instructions about what to do next.
