How to explain side effects so your doctor understands

Say what you feel, when it happens, how strong it is from 0 to 10, and what it stops you doing. Dated, scored notes are easier for a doctor to act on than "I haven't felt great". You are describing real changes, and a clear format helps.

The four-part sentence

"[Symptom], [when], [score] out of 10, and it stops me from [what]." Example: "Nausea, four days after each cycle, 7 out of 10, and it stops me from eating a full meal."

Prepare in 5 minutes

  1. Pick your three worst symptoms since last time.
  2. Write one four-part sentence for each.
  3. Add what you tried and whether it helped.
  4. Open the appointment with the most important one.

If you feel brushed off

Ask: "What would you do if this gets worse?" and "Who do I call?" You can also ask for your concern to be written in your notes. See getting your symptoms taken seriously.
