Logynon ED is a combined oral contraceptive pill containing levonorgestrel and ethinylestradiol. 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 and 7 inactive tablets. When taken correctly, Logynon ED is over 99% effective at preventing pregnancy.
