How Does This Contraceptive Work?

Jencycla and other progestin-only oral contraceptives stop ovulation in only about half of the women who take them. Because this drug is not very effective at preventing ovulation, it also relies on other mechanisms to prevent pregnancy. Jencycla alters the lining of the uterus (the endometrium), making it less receptive to an embryo. It also changes the cervical mucus (the fluid of the cervix, which is the lower, narrow part of the uterus that is connected to the vagina), making it more difficult for sperm to enter the uterus.
Unlike combined oral contraceptives, there are no inactive or "placebo" pills in each pack of Jencycla. Every tablet contains the active hormone, and there is no break in between pills or packs. Because there are no breaks, menstrual periods often occur at irregular intervals.

Is It Safe for Children and Teen to Use Jencycla?

Jencycla is approved for use in women of reproductive age. This means that it is not approved for girls who have not yet had their first menstrual period.

What About Off-Label Jencycla Uses?

On occasion, your healthcare provider may recommend this pill for something other than contraception. This is called an "off-label" use. At this time, there are no universally accepted off-label uses for Jencycla.
