Other info to think about when joining a study

During study visits, someone from the study team may ask about your adherence to the study directions. That could mean following the exact directions for taking the investigational medicine or writing journal entries at specific time points.

When you are reading through the consent form you may see that it says you could be removed from the study by the investigator if you are unable to follow the study procedures.

You may wish to ask what you should do if you were unable to follow the study directions on a particular day. For example, if you forgot to take the study treatment at the right time.

If you have a hard time following the study procedures, let the study team know so they can help you.
