More Info
In a crossover trial, one group of participants receives study treatment A first followed by study treatment B, while the other group of participants receives study treatment B followed by study treatment A. There is sometimes a wash-out period in between.
The order in which the study treatments are given is randomized.
A benefit of this is that confounding may be reduced as each participant serves as their own “control.”

If you are deciding whether to join a crossover trial, you may want to ask the research team more about how long the study will take and if there is a washout period between taking each study treatment.
Before joining the study, you could also ask the study team what the process might be if you think one study treatment is working better for you than another.
