Start taking norethisterone 3 days before your period is due.

Treatment may be supplied for up to 14 days, depending on your needs.

Your period will usually begin 2–3 days after you stop taking the tablets.

This treatment is not a contraceptive,

You should use contraception if pregnancy is a possibility,

Norethisterone works by copying a natural hormone in your body.

This prevents the lining of your womb from shedding, which delays the start of your period.

• headache or mood changes

Side effects may be more likely the longer treatment is taken.
