Which side effects to report right away

The list depends on your treatment, so ask your team for it in writing, with the number to call day and night. When in doubt, call. Reporting early is part of safe treatment, and teams expect these calls.

Ask your team on day 1

  1. Which symptoms must I report right away for my treatment?
  2. What number do I call during the day, and at night or weekends?
  3. What should I do if I cannot reach anyone?
  4. Which symptoms can wait until my next appointment?

Make it easy to follow

  • Write the list and the numbers on paper and on your phone.
  • Share it with the person who lives with you.
  • Keep it where you will find it quickly.

Keep a record for the rest

For symptoms that are not urgent, a daily note with scores helps you show patterns. See the symptom diary.
