Microgynon 30 is a combined oral contraceptive pill containing levonorgestrel (150 micrograms) and ethinylestradiol (30 micrograms). It prevents pregnancy by stopping ovulation, thickening cervical mucus to block sperm, and thinning the lining of the womb to reduce implantation.
Each pack contains 21 active tablets. When taken correctly, Microgynon 30 is over 99% effective at preventing pregnancy.
