Kariva is a combination birth control pill containing female hormones that prevent ovulation (the release of an egg from an ovary).  Kariva 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.
Kariva is used to prevent pregnancy. There are many brands of this medicine available. Not all brands are listed on this leaflet.
Kariva may also be used for purposes not listed in this medication guide.
