norethisterone to delay period

[mammya]

My DD has been prescribed norethisterone to delay her period so that it doesn't happen during her residential school trip. She has to take 3 pills a day, but it's not specified if she should take them all in one go or at different times of day. Does anyone know?
Thanks :)

from this it looks like you take them through the day and not all at once

Breakfast, Lunch, Dinner. I've just finished a course so i didn't have my period while camping!

thanks, that's what I thought... Annoying though, it would be easier if they could be taken all in one go!
