NuvaRing contains 2 kinds of female hormones, estrogen and progestin, which work together to prevent pregnancy. They are the same kind of hormones found in the pill and they work the same way to prevent pregnancy even though they are administered differently with NuvaRing.
Once you place NuvaRing in your vagina, it releases a continuous low dose of hormones that helps prevent pregnancy. When used as directed, NuvaRing has been shown to be 98% effective. You don’t have to think about taking it every day.
NuvaRing is used in a 4-week cycle. Keep NuvaRing in your vagina for 3 weeks (21 days) and then remove it for a 1-week (7-day) break. Regularly check that NuvaRing is in your vagina (for example, before and after intercourse) to ensure that you are protected from pregnancy.
Insert a new NuvaRing after the 1-week break. The new ring should be inserted on the same day of the week and at the same time that you inserted it the last month, even if your period has not stopped.
