Product description

Norethisterone 5mg tablets work by mimicking the effects of the natural hormone, progesterone.

Through your menstrual cycle levels of progesterone will naturally rise and fall.  Taking norethisterone tablets a few days before your period is due to start can temporarily stop the shedding of the womb lining, which helps to stop/delay your period.

Once you stop taking Norethisterone, your progesterone levels will return to normal and your next period will usually start again within 2-3 days.

Norethisterone should only be used occasionally to delay a period.  If you find that you need to use this regularly then please speak with your GP as a low-dose hormonal contraceptive (like the pill) might be more suitable for controlling frequent or heavy uncomfortable periods.  

Please note: this medicine is not a contraceptive.

Directions

You should always take this medicine as directed by your doctor or pharmacist. Period delay tablets should be taken with water. The normal dosage for these tablets is:

Delay your period - 1 tablet three times a day starting at least three days before your period is due. Your period should occur 2-3 days after you have stopped taking the medicine.

This medicine is intended for short-term occasional use to delay a period during times of inconvenience, therefore the maximum number of tablets we will prescribe is 60 tablets which would be sufficient to delay your period for up to 17 days.

For occasional use, we recommended that Norethisterone is not taken any more frequently than 2-3 times per year with regular normal periods between use.
