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)).

    • If you take these medications before you check for fever, they may lower your temperature and you may not know you have an infection.

 

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

      OR

    • 38.0°C (100.4°F) or higher for at least one hour.

 

If you do have a fever:

  • If you haven't been given any instructions on how to manage your fever, try to contact your health care team.

  • If you are not able to talk to your health care team for advice, get emergency medical help right away.

 

If you do not have a fever but have mild symptoms such as headache or mild pain:

  • Ask your health care team about the right medication for you. Acetaminophen (Tylenol®) is a safe choice for most people.

  • 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.

  • DO talk to your health care team about your risk of getting other cancers and heart problems during or after this treatment.

  • DO protect your skin from the sun. Wear a long sleeved shirt, long pants and a hat. Apply sunscreen with UVA and UVB protection and an SPF of at least 30. Your skin may be more sensitive to the sun and you could develop a bad sunburn or rash more easily.
