Understanding informed consent
Before you can take part in a clinical trial, the research team must explain exactly what is involved, what the possible benefits and risks are, and what alternatives you have.
You'll be given written information to take home and time to ask questions. Only when you're ready will you be asked to sign a consent form. Signing doesn't lock you in — you can still change your mind later.
Good consent is an ongoing conversation. If anything changes during the study, the team must tell you so you can decide whether you still want to continue.
