Novelon Tablet contains a combination of synthetic hormones, Ethinyl estradiol and Desogestrel, which work together to prevent ovulation, thicken cervical mucus to prevent sperm penetration, and alter the uterine lining to prevent implantation. This mechanism provides highly effective contraception while also regulating menstrual cycles and alleviating symptoms of hormonal imbalance such as irregular periods, acne, and menstrual cramps.
