Noriday is a progestogen-only contraceptive pill (POP or “mini-pill”) containing norethisterone 350 micrograms. It prevents pregnancy mainly by thickening cervical mucus to block sperm, changing the lining of the womb, and sometimes by suppressing ovulation.
Each pack contains 28 tablets and is taken continuously without a break. When taken correctly, Noriday is a reliable form of contraception.
