Delaying a period can be useful for holidays, sport, exams or big events. In Ireland, a short course of a prescription tablet called norethisterone can be used to postpone bleeding if it is suitable for you.
What is period delay and how does it work?
Period delay means shifting the date your next bleed starts by taking a hormone tablet for a short time. In Ireland the most used option is norethisterone, a synthetic progesterone that holds the womb lining stable. When you stop taking it, a withdrawal bleed usually starts two to three days later.
Who can use norethisterone for period delay?
- Adults who are not currently pregnant and are not using a combined hormonal contraceptive
- People without a history of blood clots, certain liver problems or hormone-sensitive cancers
- Those who are not breastfeeding a young baby
A doctor will check your medical history and medicines to confirm suitability. If norethisterone is not right for you, alternative approaches are available.
How to take norethisterone for period delay
- Start three days before your expected period
- Take one tablet three times a day at evenly spaced times
- You can continue for up to fourteen days if advised
- When you stop, a bleed usually begins within two to three days
Always follow the specific directions on your prescription. If you forget a dose, take it when remembered unless it is close to the next dose.
