Previfem is a combination birth control pill containing female hormones that prevent ovulation (the release of an egg from an ovary). Previfem also causes changes in your cervical mucus and uterine lining, making it harder for sperm to reach the uterus and harder for a fertilized egg to attach to the uterus.

Previfem is used as contraception to prevent pregnancy. There are many available brands of this medicine. Not all brands are listed on this leaflet.
