Gedarel 20/150 is a combined oral contraceptive pill containing ethinylestradiol (20 micrograms) and desogestrel (150 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, Gedarel is over 99% effective at preventing pregnancy.
