Cigarette smoking increases the risk of serious heart problems associated with use of Natazia. This risk increases with age (especially in women older than 35 years old) and with frequent smoking. Women who are older than 35 years old and smoke should not use Natazia.
Natazia is used for:
Preventing pregnancy. It may also be used to treat heavy menstrual bleeding in women who use Natazia for birth control. It may be used for other conditions as determined by your doctor.
Natazia is a combination birth control pill. It works by preventing ovulation. It may also change cervical mucus to prevent the sperm from reaching the egg and change the lining of the uterus to prevent a fertilized egg from implanting in the uterus. It works to decrease heavy menstrual bleeding by thinning the lining of the uterus.
