The uses of Loette include: This combination hormone medication is used to prevent pregnancy. It contains 2 hormones: a progestin and an estrogen. These hormones prevent pregnancy in 3 ways. One way is by preventing the release of an egg (ovulation). A second way is by changing the cervical mucus, making it more difficult for an egg to meet sperm (fertilization). A third way is by changing the womb lining, making it difficult for a fertilized egg to attach to the lining of the womb (implantation). A fertilized egg (embryo/unborn baby) needs to attach to the womb to receive blood and nutrients and continue to grow. If an embryo/unborn baby does not attach, it cannot survive.
Using this medication does not protect you or your partner against sexually transmitted diseases (e.g., HIV, gonorrhea).
