Loestrin is a monophasic pill and contains high concentration of estrogen. The main purpose of this pill is to prevent an egg from the ovary to release. It means that even the presence of sperm cannot fertilize the egg. With the usage of this pill, it sometimes hardens the cervical mucus and put a stop to sperm reaching the uterus. Loestrin is also called the combination of ethinyl estradiol along with progestin and ferrous fumarate. The mineral supplement is also important in Loestrin’s mechanism as it basically controls the level of hormones throughout a menstrual cycle. Doctors do not recommend this pill to any woman who suffers from high blood pressure, severe migraine and women who have history of breast cancer or uterine cancer. Women, who have also given birth, should not use Loestrin. Pregnant and breastfeeding mothers can also face serious side effects of this pill.
