Hello.
Thanks for writing to us.
You can take
norethisterone 5 mg three times a day half an hour after meals and start taking it at least 5 days before the expected date of the periods. You can continue it as long as you want to delay the periods.
I hope this information has been both informative and helpful for you.
Regards,
