About Progestogen-only Pill

This belongs to the group of medicines known as Oral Progestogen-only contraceptives .

Progestogen-only contraceptives are also known as the 'Progestogen-only Pill', 'POP' or the 'mini-pill'. They contain Progestogen which is a female sex hormone.

Progestogen-only contraceptives work by thickening the fluid in the cervix (the neck of the uterus and womb). This makes it very difficult for sperm to travel through the cervix and into the uterus in order to fertilise an egg. The hormone also affects the lining of the uterus so that is it does not become thick enough for an egg to grow. In some women, the Progestogen-only contraceptive also stops an egg being produced.

This medicine is available in tablet form.

Brands available are: Cerazette; Femulen; Micronor; Microval; Neogest; Norgeston; Noriday..
