Loestrin 20 is a combined contraceptive pill, usually just called ‘the pill’.
It contains two hormones – an oestrogen and a progestogen.
Each Loestrin 20 tablet contains two active ingredients, ethinylestradiol 20 mg and norethisterone 1 mg.
These are synthetic versions of the naturally occurring female sex hormones, oestrogen and progesterone.
HOW TO USE
Loestrin 20 tablets come in a calendar pack marked with days of the week.
You take one pill at the same time every day for 21 days and then have a seven day break.
During your seven day break you’ll usually get a withdrawal bleed that is similar to your normal period.
Start your next pack after the seven pill-free days are up, even if you are still bleeding.
