This medicine is a combined oral contraceptive and belongs to a group of drugs which is frequently called “the Pill”. It contains two types of hormone: an oestrogen, named ethinylestradiol and a progestogen type, named gestodene. These hormones stop the ovary from releasing an egg each month (ovulation). They also thicken the fluid (mucus) at the neck of the womb (cervix) making it more difficult for the sperm to reach the egg, and alter the lining of the womb to make it less likely to accept a fertilised egg. Medical researches and vast experience have shown that, if taken correctly, the Pill is an effective reversible form of contraception.This medicine, like other hormonal contraceptives, will not protect you against HIV infection (AIDS) and other sexually transmitted diseases. Only condoms can do this.
