What should I do if I feel unwell, have pain, a headache or a fever?

  • Always check your temperature to see if you have a fever before taking any medications for fever or pain (such as acetaminophen (Tylenol®) or ibuprofen (Advil®)).

How to check for fever:

Keep a digital (electronic) thermometer at home and take your temperature if you feel hot or unwell (for example, chills, headache, mild pain).

  • You have a fever if your temperature taken in your mouth (oral temperature) is:
     
    • 38.3°C (100.9°F) or higher at any time

  • Talk to your health care team before you start taking Ibuprofen (Advil®, Motrin®), naproxen (Aleve®) or ASA (Aspirin®), as they may increase your chance of bleeding or interact with your cancer treatment.

  • Talk to your health care team if you already take low dose aspirin for a medical condition (such as a heart problem). It may still be safe to take.

 

What to DO while on this medication:

  • DO check with your health care team before getting any vaccinations, surgery, dental work or other medical procedures.
