Norelgestromin is a contraceptive that women may take to help prevent pregnancy. This medication stops the woman’s body from releasing eggs each month. It also makes the uterus wall thinner and thickens the cervix to decrease the likelihood that sperm will enter the woman’s body or that a fertilized egg will implant itself in the uterus. This medication is administered through a patch applied to the skin.
Women who smoke should quit if they intend to use this medication. Smoking while on this type of contraceptive medication greatly increases the risk of a fatal heart attack or stroke. Women over the age of 35 are also at greater risk of heart attack or stroke while on contraceptive medications.
This medication only protects against pregnancy. It does not protect against HIV or any other sexually transmitted disease.
