Why asking questions matters
Being informed helps you feel more confident about your choices and what to expect. There are no "right" or "wrong" questions. What matters is understanding the information in a way that makes sense for you.
Asking questions can also help you:
- Understand your options
- Weigh benefits and risks
- Feel more prepared for what's ahead
Taking part in a clinical trial is your choice, and your consent is ongoing. You can ask questions and change your mind at any time before or during the trial. If you withdraw, the research team will explain what this means and discuss what happens to your information.
Tips for talking with your doctor
If you are going to speak to your doctor about trials, it might help if you:
- Take a family member or friend with you for support
- Plan what you would like to ask before your visit
- Write your questions down so you don't forget them
- Ask follow-up questions or new questions during or after appointments
- Use your phone or a recorder to remember what was discussed
Remember:
- You don't need to ask every question listed on this page
- These are suggestions - you can choose the questions that matter most to you
- You can ask questions over more than one appointment
- It's okay to take your time and come back with more questions later
