What RINGZA is
RINGZA is a contraceptive vaginal system used to prevent pregnancy in women for up to 1 year.
RINGZA was designed to be used repeatedly for up to 1 year
Do not use RINGZA for more than 13 cycles
How RINGZA works
RINGZA is a vaginal system made of flexible silicone. It slowly releases two female hormones: segesterone acetate (SA) and ethinyl estradiol (EE).
This prevents the release of the egg from the ovary (ovulation).
How effective was RINGZA at preventing pregnancy in clinical trials?
Clinical trials found that RINGZA was 97.5% effective at preventing pregnancy. This means that about 2 to 4 out of 100 women may become pregnant during the first year they use RINGZA.
